SIP Calculator
Explore hypothetical investment growth and the ending corpus in today's purchasing power. Returns are assumptions, not predictions.
Year-by-Year Corpus Growth
The grey bars show contributions; the purple bars show projected gains. Their relationship depends on the return assumption and contribution dates, not a fixed crossover year.
What ₹10,000/month SIP Becomes
At different return rates and tenures — so you can set realistic targets.
| TENURE | 8% p.a. | 10% p.a. | 12% p.a. ★ | 15% p.a. |
|---|---|---|---|---|
| 5 years | ₹7.34 L | ₹7.72 L | ₹8.11 L | ₹8.73 L |
| 10 years | ₹18.13 L | ₹20.15 L | ₹22.40 L | ₹26.30 L |
| 15 years | ₹33.98 L | ₹40.16 L | ₹47.59 L | ₹61.64 L |
| 20 years | ₹57.27 L | ₹72.40 L | ₹91.99 L | ₹1.33 Cr |
| 25 years | ₹91.48 L | ₹1.24 Cr | ₹1.70 Cr | ₹2.76 Cr |
| 30 years | ₹1.42 Cr | ₹2.08 Cr | ₹3.08 Cr | ₹5.63 Cr |
All return rates are hypothetical scenarios, not verified market averages or forecasts.
Keep expenses, tax and inflation separate
Published NAV returns already reflect fund expenses. Do not subtract the expense ratio again from a NAV-based CAGR. Enter a hypothetical return after expenses; this calculator does not forecast any fund's performance.
This projection is before tax and exit loads. Treatment depends on scheme, acquisition dates, holding periods, disposals and applicable year. Do not approximate it by subtracting a fixed percentage from annual returns.
And inflation: at 6% inflation, ₹1 Cr in 20 years has the purchasing power of roughly ₹31L today. Use the inflation toggle above to see what your corpus is really worth.
How the SIP Math Works
SIP returns are calculated using the future value of an annuity formula. Each monthly instalment earns compound interest from its investment date until the end. The first instalment earns returns for all 15 years; the last instalment earns only 1 month.
Earlier contributions have more time to compound in a positive-return scenario. Starting earlier also means contributing more money; compare both the total contributions and ending corpus rather than attributing the entire difference to investment returns.
Fixed contributions buy more units when NAV is lower and fewer when it is higher. They do not guarantee a lower purchase price or a better return than a lump sum; actual market paths and contribution dates determine that comparison.
Direct and regular plans: compare actual expenses
Direct plans exclude distributor commissions and have lower expenses than regular plans of the same scheme. The actual difference varies. Compare current disclosures for the same scheme and option; a fixed one-percentage-point difference is not universal.
Read the direct-versus-regular guide and AMFI’s explanation. Switching existing units can trigger tax or exit loads, unlike changing where new contributions go.
Frequently Asked Questions
What is SIP and how does it work?+
A SIP invests an amount at regular intervals. Each contribution buys units at the prevailing NAV. A lower NAV buys more units, but this does not guarantee a profit or better results than a lump sum.
What rate of return should I use for SIP calculations?+
Use several hypothetical scenarios, not one rate presented as expected performance. Enter a return after fund expenses; published NAV returns already include those expenses. No single rate suits every goal or fund.
How is SIP return different from a lumpsum return?+
A lump sum is invested at the start, while every SIP contribution has its own date. The model assumes start-of-month contributions and an effective annual return. Equal total contributions do not mean equal time in the market.
What is the effect of inflation on SIP returns?+
The ending corpus is divided by (1 + inflation rate) raised to the number of years to express today's purchasing power. Future nominal contributions are not revalued as though they were already invested today.
Should I choose SIP or lumpsum?+
Match contributions to available cash and your investment plan. A SIP spreads purchase dates but does not guarantee profit or remove market risk. This calculator does not identify market lows.
Is the SIP return in this calculator before or after tax?+
Before tax and exit loads. Treatment depends on scheme, acquisition and disposal dates, holding period and tax year. Subtracting an arbitrary percentage from an annual return is not a tax calculation.
How do I choose between direct and regular plan SIPs?+
Direct plans have lower expenses than regular plans of the same scheme because distributor commissions are excluded. Compare current disclosures and consider advice needs. NAV returns already reflect expenses.
