Project growing monthly investments with an annual SIP increase.
Private by design · Inputs and downloads stay in your browser
Start-of-month deposits; SIP increases once per year. Return assumptions are not guarantees.
How it works
Enter a starting monthly SIP, expected annual return, duration and annual increase. Calculate to see yearly contributions and growth. The increase takes effect after each block of 12 monthly deposits. Reset restores the example inputs.
Method and formula
Monthly contribution in year y = starting SIP × (1 + annual increase / 100)^(y − 1). Each month, balance = (previous balance + contribution) × (1 + annual return / 1200). This matches the beginning-of-month convention in the original SIP calculator. Total profit is the same as estimated returns; it is not an additional amount.
Example
With a ₹5,000 starting SIP and a 10% annual increase, monthly contributions are ₹5,000 in year 1, ₹5,500 in year 2 and ₹6,050 in year 3. Contributions over those three years total ₹1,98,600. With a 0% return, final value equals those contributions.
Assumptions and limits
The nominal annual return is divided by 12 and held constant. No taxes, fees, inflation, missed deposits or negative market returns are modeled. Real returns can be negative. The model rejects results above ₹10^18 rather than returning an overflow.
Frequently asked questions
When does the SIP increase?
After every 12 monthly contributions, the next monthly amount increases by the entered percentage.
Is total profit separate from returns?
No. Estimated returns and total profit refer to final value minus total contributions.
Can I compare with a fixed SIP?
Yes. Enter a 0% annual increase to use the same monthly deposit throughout.
