Choosing the best SIP amount to start is not about picking the biggest number you can afford. It is about finding the amount that keeps your portfolio alive long enough for compounding to do its real work. A ₹500 SIP you sustain for 20 years beats a ₹5,000 SIP you abandon after three.
This guide breaks down every starting amount — ₹500, ₹1,000, ₹2,000, and ₹5,000 — using the SIP future value formula, real rupee corpus projections at 10%, 12%, and 14% CAGR, post-tax XIRR analysis, inflation-adjusted real returns, and a step-up SIP comparison that most articles completely ignore. By the end, you will know exactly which SIP amount matches your income level, your goal, and your tax bracket.

How SIP Returns Are Actually Calculated (The Formula Most Sites Skip)
Every SIP calculator runs on a single compounding formula. Understanding it helps you verify any number you see — and catch misleading projections.
The standard SIP future value formula is:
FV = P \times \frac{(1 + r)^n - 1}{r} \times (1 + r)Where:
- FV = Future Value (corpus at maturity)
- P = Monthly SIP amount in ₹
- r = Monthly rate of return = Annual rate ÷ 12
- n = Total number of monthly instalments
Worked example — ₹1,000 SIP for 10 years at 12% CAGR:
r = \frac{12\%}{12} = 1\% = 0.01 n = 10 \times 12 = 120 \text{ months} FV = 1000 \times \frac{(1.01)^{120} - 1}{0.01} \times (1.01) FV = 1000 \times \frac{3.3004 - 1}{0.01} \times 1.01 \approx ₹2,32,339You invest ₹1,20,000. You receive ₹2,32,339. The ₹1,12,339 is pure compounding gain — generated without any additional effort on your part.
For XIRR (the only accurate measure of SIP performance across staggered cash flows), the formula solves for rate r such that:
\sum_{i=1}^{n} \frac{-P}{(1 + r)^{t_i}} + \frac{FV}{(1 + r)^{t_n}} = 0Because each monthly instalment has a different holding period, XIRR gives a truer annualized return than CAGR for SIP portfolios. Use our SIP Calculator to estimate your annualized SIP return.
₹500 SIP: The Entry-Level Amount That Actually Works
Who Should Start With ₹500
A ₹500 monthly SIP is ideal for students, freshers earning below ₹15,000 per month, homemakers with limited surplus, or anyone building the investment habit before scaling up. The goal is not a massive corpus — it is creating an irreversible behavior pattern.
₹500 SIP Corpus Projections
| Tenure | Total Invested | At 10% CAGR | At 12% CAGR | At 14% CAGR |
|---|---|---|---|---|
| 5 Years | ₹30,000 | ₹38,965 | ₹40,735 | ₹42,574 |
| 10 Years | ₹60,000 | ₹1,03,276 | ₹1,16,170 | ₹1,31,026 |
| 15 Years | ₹90,000 | ₹2,08,676 | ₹2,51,521 | ₹3,04,636 |
| 20 Years | ₹1,20,000 | ₹3,79,684 | ₹4,99,574 | ₹6,63,756 |
| 25 Years | ₹1,50,000 | ₹6,64,073 | ₹9,44,858 | ₹13,69,920 |
Inflation-Adjusted Real Value of ₹500 SIP Corpus
Most competitor articles show only nominal corpus. Here is what those numbers are worth in today's purchasing power, assuming 6% average inflation:
Real Value formula:
Real\ Value = \frac{Nominal\ Corpus}{(1 + inflation)^{years}}₹500 SIP at 12% for 20 years → Nominal: ₹4,99,574 → Real Value: ≈ ₹1,55,800
₹500 SIP at 12% for 25 years → Nominal: ₹9,44,858 → Real Value: ≈ ₹2,20,000
This is not to discourage you. It means you must either extend tenure, step up the SIP amount annually, or use both strategies together. Even in real terms, the habit and the compounding base you build with ₹500 become the foundation for everything that follows.
₹500 Step-Up SIP vs Flat ₹500 SIP (12% CAGR, 20 Years)
| Strategy | Starting Amount | Annual Step-Up | Corpus at 20 Years |
|---|---|---|---|
| Flat SIP | ₹500/month | 0% | ≈ ₹4,99,574 |
| Step-Up SIP | ₹500/month | 10% per year | ≈ ₹9,80,000 |
A 10% annual step-up nearly doubles your corpus at the same starting point. Use our Step-Up SIP Calculator to model your own increase schedule.
Post-Tax Reality for ₹500 SIP
At a ₹500 SIP over 10 years with 12% CAGR, your gain is approximately ₹56,170. This is comfortably below the ₹1,25,000 annual LTCG exemption limit. For most investors at this ticket size, tax liability on a ₹500 SIP will be zero or negligible at the time of redemption if structured correctly.
₹1,000 SIP: The Most Popular Starting Point in India
Who Should Start With ₹1,000
A ₹1,000 monthly SIP suits salaried individuals earning ₹15,000–₹35,000 per month, young professionals with EMI obligations, or anyone who has outgrown the ₹500 habit and wants their first meaningful wealth-building position.
₹1,000 SIP Corpus Projections
| Tenure | Total Invested | At 10% CAGR | At 12% CAGR | At 14% CAGR |
|---|---|---|---|---|
| 5 Years | ₹60,000 | ₹77,930 | ₹81,470 | ₹85,149 |
| 10 Years | ₹1,20,000 | ₹2,06,552 | ₹2,32,339 | ₹2,62,053 |
| 15 Years | ₹1,80,000 | ₹4,17,352 | ₹5,03,042 | ₹6,09,272 |
| 20 Years | ₹2,40,000 | ₹7,59,368 | ₹9,99,148 | ₹13,27,512 |
| 25 Years | ₹3,00,000 | ₹13,28,146 | ₹18,89,716 | ₹27,39,840 |
| 30 Years | ₹3,60,000 | ₹22,79,325 | ₹35,29,914 | ₹55,94,601 |
What ₹1,000 SIP Can Realistically Do
At 12% CAGR over 30 years, a ₹1,000 monthly SIP generates over ₹35 lakh from just ₹3.6 lakh invested. The compounding multiplier here is 9.8x — meaning every rupee invested returns nearly 10 rupees. This is the foundational argument for starting early, not starting big.
XIRR vs CAGR: Why They Differ for ₹1,000 SIP
When you invest ₹1,000 for 120 months, only the first instalment compounds for 10 full years. The last instalment barely compounds for one month. The effective annualized XIRR on a 10-year 12% CAGR assumption is typically 11.5%–11.8% — slightly lower than the headline 12%, because the average holding period of your money is approximately 5–6 years, not 10.
This is why XIRR is the honest number. Always ask for XIRR, not just CAGR, when comparing fund performance on your SIP.
Post-Tax Return: ₹1,000 SIP for 20 Years at 12%
Nominal corpus: ₹9,99,148
Total invested: ₹2,40,000
Total gain: ₹7,59,148
LTCG tax (12.5% above ₹1,25,000 exemption):
Tax = (₹7,59,148 - ₹1,25,000) \times 12.5\% = ₹6,34,148 \times 0.125 = ₹79,268Post-tax corpus: ₹9,99,148 − ₹79,268 = ≈ ₹9,19,880
Note: If you practice annual tax harvesting — redeeming and reinvesting up to ₹1,25,000 of gains each year — you can legally reduce this tax burden to near zero over a long SIP tenure.
₹2,000 SIP: The Sweet Spot for Middle-Income Earners
Who Should Start With ₹2,000
A ₹2,000 monthly SIP is the practical sweet spot for salaried earners with income between ₹30,000–₹60,000, individuals with low to moderate EMI obligations, or anyone ready to graduate from a starter SIP into a goal-oriented investment.
₹2,000 SIP Corpus Projections
| Tenure | Total Invested | At 10% CAGR | At 12% CAGR | At 14% CAGR |
|---|---|---|---|---|
| 5 Years | ₹1,20,000 | ₹1,55,861 | ₹1,62,941 | ₹1,70,298 |
| 10 Years | ₹2,40,000 | ₹4,13,104 | ₹4,64,678 | ₹5,24,107 |
| 15 Years | ₹3,60,000 | ₹8,34,704 | ₹10,06,084 | ₹12,18,544 |
| 20 Years | ₹4,80,000 | ₹15,18,736 | ₹19,98,296 | ₹26,55,024 |
| 25 Years | ₹6,00,000 | ₹26,56,292 | ₹37,79,432 | ₹54,79,680 |
₹2,000 SIP for Child Education Planning
If your child is newborn today, a ₹2,000 SIP for 18 years at 12% CAGR produces approximately ₹16.5 lakh. This is a solid base for undergraduate education costs — especially if combined with a step-up of 10% annually, which takes the corpus to over ₹30 lakh for the same period.
Pair this with our SIP Calculator to back-calculate the exact SIP amount needed for your child's target education corpus.
₹2,000 SIP vs Recurring Deposit: Real Comparison
| Instrument | Monthly | Tenure | Rate | Maturity Value | Post-Tax |
|---|---|---|---|---|---|
| Recurring Deposit | ₹2,000 | 10 Years | 7% p.a. | ≈ ₹3,48,000 | Taxed at slab (e.g. 30% → ₹3,07,200) |
| Equity SIP (12%) | ₹2,000 | 10 Years | 12% p.a. | ≈ ₹4,64,678 | LTCG 12.5% above ₹1.25L → ≈ ₹4,38,000 |
The post-tax advantage of equity SIP over RD is substantial, especially for investors in the 20% and 30% tax brackets where RD interest is fully added to income. See our SIP Calculator for a customizable projection to compare against your FD rate.
₹5,000 SIP: Serious Wealth Creation Begins Here
Who Should Start With ₹5,000
A ₹5,000 monthly SIP is appropriate for salaried professionals earning ₹50,000–₹1,20,000 per month, entrepreneurs with stable monthly cash flow, dual-income households building a retirement or home purchase corpus, or anyone transitioning from a smaller SIP after an income increment.
₹5,000 SIP Corpus Projections
| Tenure | Total Invested | At 10% CAGR | At 12% CAGR | At 14% CAGR |
|---|---|---|---|---|
| 5 Years | ₹3,00,000 | ₹3,89,652 | ₹4,07,353 | ₹4,25,744 |
| 10 Years | ₹6,00,000 | ₹10,32,760 | ₹11,61,695 | ₹13,10,267 |
| 15 Years | ₹9,00,000 | ₹20,86,760 | ₹25,15,210 | ₹30,46,360 |
| 20 Years | ₹12,00,000 | ₹37,96,840 | ₹49,95,740 | ₹66,37,560 |
| 25 Years | ₹15,00,000 | ₹66,40,730 | ₹94,48,580 | ₹1,36,99,200 |
| 30 Years | ₹18,00,000 | ₹1,13,96,625 | ₹1,76,49,570 | ₹2,79,73,005 |
The ₹5,000 SIP at 25 Years: Why ₹94 Lakh Matters
At 12% CAGR over 25 years, ₹5,000/month → ≈ ₹94.5 lakh. You invested ₹15 lakh. The compounding multiplier is 6.3x. At 14% CAGR (achievable historically via mid/small-cap funds over long cycles), the same SIP produces ₹1.37 crore — crossing the crore milestone purely on ₹5,000 per month invested consistently.
₹5,000 SIP — Step-Up Strategy to ₹1 Crore
If you start a ₹5,000 SIP with a 10% annual step-up at 12% CAGR:
| Strategy | Starting SIP | Step-Up | Corpus at 20 Years |
|---|---|---|---|
| Flat SIP | ₹5,000/month | 0% | ≈ ₹49.96 lakh |
| Step-Up SIP (10%) | ₹5,000/month | 10% annually | ≈ ₹1.16 crore |
A 10% annual step-up — adding just ₹500 more each year in year one — delivers a corpus that is 2.3x larger than the flat SIP, without any increase in financial stress because the step-up tracks typical annual income growth.
Post-Tax XIRR on ₹5,000 SIP at 20 Years
Nominal corpus at 12% CAGR: ₹49,95,740
Total invested: ₹12,00,000
Total gains: ₹37,95,740
Post-tax corpus: ₹49,95,740 − ₹4,58,843 = ≈ ₹45,36,897
Inflation-adjusted real value (6% inflation, 20 years):
Real\ Value = \frac{₹45,36,897}{(1.06)^{20}} = \frac{₹45,36,897}{3.207} \approx ₹14,14,500In today's rupees, ₹45 lakh twenty years from now is worth approximately ₹14 lakh in purchasing power. This underscores why step-up SIPs, longer tenures, and early starts are non-negotiable for real wealth creation.
Side-by-Side Comparison: All Four SIP Amounts at 12% CAGR for 20 Years
| Monthly SIP | Invested | Nominal Corpus | Post-Tax Corpus | Real Value (6% Inflation) | Step-Up Corpus (10% p.a.) |
|---|---|---|---|---|---|
| ₹500 | ₹1,20,000 | ₹4,99,574 | ≈ ₹4,52,000 | ≈ ₹1,41,000 | ≈ ₹9,80,000 |
| ₹1,000 | ₹2,40,000 | ₹9,99,148 | ≈ ₹9,19,880 | ≈ ₹2,87,000 | ≈ ₹19,60,000 |
| ₹2,000 | ₹4,80,000 | ₹19,98,296 | ≈ ₹18,15,000 | ≈ ₹5,66,000 | ≈ ₹39,20,000 |
| ₹5,000 | ₹12,00,000 | ₹49,95,740 | ≈ ₹45,36,897 | ≈ ₹14,14,500 | ≈ ₹1,16,00,000 |
Corpus figures are estimates based on 12% CAGR. Actual returns vary with market conditions. Post-tax figures assume full LTCG treatment without annual tax harvesting. Step-up figures assume 10% annual increase starting from year 2.
How to Choose the Right SIP Amount for Your Income
The 10–15% Rule
A widely accepted framework for SIP sizing is to invest 10–15% of your take-home monthly income into SIPs. This leaves sufficient buffer for living expenses, emergency fund contributions, and short-term goals.
| Monthly Take-Home | Recommended SIP Range | Starting SIP Amount |
|---|---|---|
| ₹10,000 – ₹20,000 | ₹1,000 – ₹3,000 | ₹500 – ₹1,000 |
| ₹20,000 – ₹40,000 | ₹2,000 – ₹6,000 | ₹1,000 – ₹2,000 |
| ₹40,000 – ₹80,000 | ₹4,000 – ₹12,000 | ₹2,000 – ₹5,000 |
| ₹80,000 – ₹1,50,000 | ₹8,000 – ₹22,500 | ₹5,000+ |
The starting amount matters less than the step-up commitment. A ₹500 SIP that increases by 10% every year becomes a ₹1,298 SIP after 10 years — without you ever making an active decision to increase it.
Goal-Based SIP Sizing
If you know your target corpus and timeline, reverse-engineer the required SIP amount:
P = \frac{FV \times r}{[(1 + r)^n - 1] \times (1 + r)}Example: You need ₹50 lakh in 20 years at 12% CAGR. What monthly SIP is required?
r = \frac{0.12}{12} = 0.01,\quad n = 240 P = \frac{50,00,000 \times 0.01}{[(1.01)^{240} - 1] \times 1.01} = \frac{50,000}{[9.8046 - 1] \times 1.01} = \frac{50,000}{8.8927} \approx ₹5,622You need approximately ₹5,622 per month to reach ₹50 lakh in 20 years at 12% CAGR. Use our Lumpsum Calculator to compare whether a one-time investment could reach the same goal faster.
The SIP Amount Is Less Important Than These Three Factors
1. Starting Age and Tenure (Time Beats Amount Every Time)
Consider two investors — Priya and Rajan:
- Priya starts a ₹1,000 SIP at age 25 and runs it for 35 years at 12% → corpus: ≈ ₹64 lakh
- Rajan starts a ₹2,000 SIP at age 35 and runs it for 25 years at 12% → corpus: ≈ ₹37.8 lakh
Priya invests half the monthly amount but ends up with 69% more corpus — purely because of the 10-year head start. Starting date is the most powerful variable in any SIP equation.
2. Annual Step-Up Discipline
A 10% annual step-up is not about investing more aggressively. It is about keeping your investment growing at approximately the rate of your income growth. Most salaried Indians receive 8–12% annual increments. Mirroring that in your SIP is simply maintaining the same financial effort, not increasing it.
3. Fund Selection and Expense Ratio Impact
A 0.5% difference in expense ratio compounded over 20 years on a ₹5,000 SIP reduces your final corpus by approximately ₹3–4 lakh. Direct plans (available via direct fund platforms or AMC websites) have expense ratios 0.5–1% lower than regular plans — this is a guaranteed return improvement with zero market risk.
ELSS SIP: Tax-Saving with Any Starting Amount
An ELSS (Equity Linked Savings Scheme) SIP provides a deduction under Section 80C of up to ₹1,50,000 per financial year. This makes every rupee of your SIP do double duty — building wealth while reducing your taxable income.
| SIP Amount | Annual Contribution | 80C Benefit (30% slab) | Effective Cost |
|---|---|---|---|
| ₹500/month | ₹6,000 | ₹1,800 | ₹4,200 |
| ₹1,000/month | ₹12,000 | ₹3,600 | ₹8,400 |
| ₹2,000/month | ₹24,000 | ₹7,200 | ₹16,800 |
| ₹5,000/month | ₹60,000 | ₹18,000 | ₹42,000 |
| ₹12,500/month | ₹1,50,000 | ₹45,000 | ₹1,05,000 |
Note: ELSS comes with a mandatory 3-year lock-in per instalment. Because each SIP instalment starts its own lock-in clock, your SIP is not simultaneously liquid — plan redemptions accordingly. Use our SIP Calculator to project your ELSS corpus alongside your expected tax savings.
Common Mistakes to Avoid at Every SIP Amount
Pausing SIP During Market Corrections
Market corrections are precisely when rupee cost averaging is working hardest for you. When NAVs fall, each ₹500 or ₹5,000 instalment buys more units. Pausing your SIP during a fall converts a mathematical advantage into a permanent loss of units at low prices.
Splitting Into Too Many Small SIPs
Investing ₹500 each into 10 different funds does not diversify your risk. It creates administrative complexity and delivers identical equity market exposure as a single ₹5,000 SIP in a well-diversified index fund. Concentrate your SIP into 2–4 funds maximum.
Ignoring the Expense Ratio on Small Amounts
On a ₹500 SIP in a regular plan with 1.5% expense ratio, you lose ₹7.50 per month to fund management costs before returns are calculated. On a direct plan at 0.5%, you lose ₹2.50. Small difference monthly — but over 20 years, the direct plan advantage compounds into lakhs.
Not Linking SIP to a Specific Goal
SIPs without goals are vulnerable to premature withdrawal. When you know a ₹2,000 SIP is specifically for your child's education in 18 years, you are psychologically less likely to break it for a discretionary purchase. Goal-tagging is the simplest behavioral finance tool available to any investor.
Frequently Asked Questions
The minimum SIP amount in most mutual fund schemes is ₹500 per month. Some funds accept ₹100 per month, while a few schemes (especially institutional or specialized funds) may require higher minimums. Check the Scheme Information Document of your chosen fund for the exact minimum.
Yes. A ₹500 SIP is worth it for three reasons. First, it creates the investment habit before you have more money to invest. Second, it builds a compounding base — ₹500 at 12% CAGR for 25 years becomes nearly ₹9.5 lakh. Third, a ₹500 SIP with a 10% annual step-up nearly doubles that corpus to ₹9.8 lakh and the amount becomes increasingly significant as your income grows.
The SIP amount required to reach ₹1 crore depends on your timeline. At 12% CAGR: ₹5,622/month for 20 years, ₹3,000/month for 25 years, or ₹1,630/month for 30 years. Starting early reduces the required monthly amount dramatically. Use our SIP Calculator to reverse-engineer your exact required amount.
Yes. This is called a Step-Up SIP or Top-Up SIP. You can begin with ₹1,000 and instruct your fund house to increase the amount by a fixed rupee amount or percentage each year. A 10% annual step-up on a ₹1,000 SIP means you invest ₹1,100 in year two, ₹1,210 in year three, and so on — significantly increasing your final corpus.
A ₹5,000 SIP at 12% CAGR for 30 years produces approximately ₹1.76 crore. Whether this is sufficient for retirement depends on your age at retirement, expected monthly expenses, and inflation assumptions. In today's purchasing power terms (6% inflation over 30 years), ₹1.76 crore equals approximately ₹30 lakh — which funds about 8–10 years of a ₹25,000/month lifestyle. Most retirement goals require higher SIP amounts or step-up strategies.
For equity mutual fund SIPs, gains on units held more than 12 months are taxed as Long Term Capital Gains (LTCG) at 12.5% on gains exceeding ₹1,25,000 per financial year. Gains on units held under 12 months are Short Term Capital Gains (STCG) taxed at 20%. In a long-running SIP at redemption, most gains qualify as LTCG. Tax harvesting — redeeming and reinvesting ₹1,25,000 of gains each year — can legally reduce your total lifetime tax liability.
Direct plans have no distributor commission, resulting in 0.5–1% lower annual expense ratios compared to regular plans. On a ₹5,000 SIP over 20 years at 12% CAGR, switching from a 1.5% regular plan to a 0.5% direct plan can add ₹3–5 lakh to your final corpus. Unless you need active advisory support, direct plans are almost always the better choice.
CAGR (Compound Annual Growth Rate) measures a single investment's growth from one point to another. XIRR (Extended Internal Rate of Return) calculates the annualized return across multiple cash flows at different dates — which is exactly what a SIP is. Because each monthly SIP instalment has a different holding period, XIRR is the only accurate measure of your actual SIP performance. CAGR overstates or understates SIP returns depending on market timing.
Final Word: The Best SIP Amount Is the One You Start Today
Every corpus projection in this article rests on a single assumption: that the SIP runs without interruption. The compounding mathematics work regardless of whether the amount is ₹500 or ₹5,000. The question is never which amount is perfect — it is which amount you will actually sustain.
Start with the amount that does not cause financial stress. Build the habit. Add a step-up. Let time and compounding do the rest.
