About the SIP Calculator
What is the SIP Calculator?
A Systematic Investment Plan (SIP) invests a fixed amount in a mutual fund every month. Regular investing builds discipline, averages your purchase cost across market ups and downs (rupee cost averaging), and lets compounding work on every instalment.
Enter your monthly SIP, the return you expect and the investment period. You can add an annual step-up (raising the SIP each year as your income grows), a one-time lump sum and a target corpus. The calculator projects the maturity value, total invested and wealth gained, and tells you the SIP required to hit your target.
How to use the SIP Calculator
- Monthly SIP (₹) (sample: 5,000)
- Expected Return (% per year) (sample: 12)
- Investment Period (Years) (sample: 15)
- Annual Step-Up (%) — how much you will increase the SIP each year (0 for a flat SIP). (sample: 10)
- Lump Sum (₹) — an optional one-time investment at the start. (sample: 0)
- Target Corpus (₹) — your goal amount; used to calculate the SIP needed. (sample: 1,00,00,000)
- Press Calculate SIP (results also refresh as you type). The result card shows the Projected Corpus, along with Total Invested, Wealth Gained, Required SIP for Target and Additional SIP Needed.
Formula used
FV = P × ((1 + i)ⁿ − 1) ÷ i × (1 + i)
- P = the monthly SIP amount
- i = the monthly return = expected annual return ÷ 12 ÷ 100
- n = the number of monthly instalments
This is the standard SIP formula, with each instalment invested at the start of the month. With a step-up, the SIP rises by the chosen percentage every 12 months; a lump sum compounds yearly at the expected return.
Worked example
These are the sample values already filled in the calculator above, and the result it returns for them:
| Input | Sample value |
|---|---|
| Monthly SIP (₹) | 5,000 |
| Expected Return (% per year) | 12 |
| Investment Period (Years) | 15 |
| Annual Step-Up (%) | 10 |
| Lump Sum (₹) | 0 |
| Target Corpus (₹) | 1,00,00,000 |
| Result | Value |
|---|---|
| Projected Corpus | ₹43,41,925 |
| Total Invested | ₹19,06,349 |
| Wealth Gained | ₹24,35,576 |
| Required SIP for Target | ₹11,516 |
| Additional SIP Needed | ₹6,516 |
Tips for using the SIP Calculator
- Equity mutual fund returns are not guaranteed; use 10–12% for long-term planning and check a lower rate too.
- A 10% yearly step-up can nearly double the final corpus over 20 years compared with a flat SIP.
- Stay invested through market falls — SIP instalments buy more units when prices are low.
- Long-term capital gains on equity funds above ₹1.25 lakh a year are taxed at 12.5%.
