₹11.23 L
₹12.97 L
Your ₹23.23 L is reduced to ₹12.97 L in today's purchasing power at 6% inflation. That's 44% less than the headline number.
How this result is calculated
Formula: Each monthly contribution earns the selected annual return divided by 12. Contributions are added at the start of each month; an enabled step-up raises them once a year. Goal mode reverses the same calculation to estimate the starting monthly SIP.
Active assumptions: 12% annual return, 6% annual inflation, with no annual step-up. Returns and inflation are constant estimates, not forecasts or guaranteed outcomes.
Tax treatment (2026–27): When enabled, the estimate treats all gains as long-term gains from an equity-oriented fund, applies one ₹1.25 L exemption, then 12.5% tax and 4% cess. It does not model holding periods, other capital gains or losses, surcharge, STT, or fund-specific tax treatment.

How SIP Works
A Systematic Investment Plan (SIP) allows you to invest a fixed amount regularly in mutual funds. The power of SIP lies in rupee cost averaging and the compounding effect over long periods.
SIP Formula
FV = P × [((1+r)n - 1) / r] × (1+r)
Where P = monthly investment, r = monthly rate of return, n = total number of months.
What Makes This Calculator Different
Most calculators show you nominal returns: the big shiny number. But that number doesn't account for:
- Inflation: at the default 6% assumption, ₹1 crore in 20 years has about ₹31 lakhs of today's purchasing power
- LTCG Tax: when enabled, the estimate applies 12.5% + 4% cess to gains above ₹1.25 L
- Step-up: most investors increase their SIP yearly. Not accounting for this underestimates your actual corpus
SIP vs Lumpsum: Quick Comparison
If you invest ₹10,000/month SIP for 20 years at 12% returns, you get ₹99.9 lakhs. The same total amount (₹24 lakhs) invested as lumpsum on day 1 grows to ₹2.32 crores. Lumpsum wins mathematically, but SIP is practical for salaried individuals and protects against timing risk.
