Understanding Mutual Fund SIP Compounding
A Systematic Investment Plan (SIP) lets you invest a fixed amount in mutual funds at regular intervals instead of trying to time the market. The instalments continue automatically through rallies and corrections, which builds discipline and turns investing into a monthly habit rather than a one-off decision. If the concept is new, start with our guide to what a SIP is or the short SIP glossary entry.
Each instalment buys units at the fund's prevailing net asset value (NAV), so a falling market means more units for the same money and a rising market means fewer. This is rupee cost averaging. The real engine, though, is compounding: gains earned in one year go on to earn their own returns. A ₹5,000 monthly SIP at a 12% CAGR grows to about ₹24 lakh in 15 years, and the same instalment compounds to roughly ₹85 lakh over 25 years.
The calculator above uses CAGR-based monthly compounding, which is standard for comparing SIP projections. Day to day, NAV movements decide how many units each instalment buys. If you already have a large sum ready to deploy instead, weigh the two approaches in the SIP vs lump sum comparison.

Frequently Asked Questions
Formula & Mathematical Approach
The Systematic Investment Plan (SIP) calculator uses the monthly equivalent interest rate of the expected annual return to model growth.
Show Plain Text / Excel Formula
i = (1 + Return Rate / 100) ^ (1 / 12) - 1 Future Value = Monthly SIP * [((1 + i) ^ Months - 1) / i] * (1 + i)
Key Assumptions
- Monthly deposits are made at the beginning of each monthly interval (annuity-due).
- Compounding is calculated monthly using the CAGR-equivalent rate.
- The expected return rate is steady and constant throughout the period.
- Taxation and inflation are calculated steadily on the final accumulated corpus.
- Tax rules are estimated based on regulations last reviewed in June 2026.
