SIP calculator
A systematic investment plan puts the same amount in every month. Enter the amount, the return you expect and the years to see the final value, the money you put in and the growth. A step-up raises the monthly amount each year.

How to use it
- Enter how much you invest each month and any starting amount.
- Enter the yearly return you expect and the number of years.
- Optionally add a yearly step-up if you plan to raise the monthly amount over time.
How it works
The monthly rate is the yearly return ÷ 12. For every month the balance is multiplied by (1 + monthly rate) and the instalment is added. With no step-up and no starting amount this equals instalment × ((1 + i)^n − 1) ÷ i.
Worked example
Investing 500 a month for 1 year at 12% a year (1% a month) gives 500 × 12.6825 = 6,341.25, of which 6,000 is your money and 341.25 is growth. With 100 a month for 3 years at 0% and a 10% step-up you invest 1,200 + 1,320 + 1,452 = 3,972.
Tips
- Raising the amount each year with your income can matter more than chasing a higher return.
- Test a low return and a high one to see the range, not a single number.
- These are illustrations, not financial advice.
Frequently asked questions
How is the final value calculated?
Each month the balance grows by the yearly return divided by 12, then the monthly amount is added at the end of the month. This repeats for every month of the plan, and the result is the final value.
What does the yearly step-up do?
At the start of each new year the monthly amount is raised by the percentage you enter. A 10% step-up turns 100 a month into 110 in year two and 121 in year three.
Is the return guaranteed?
No. Real markets do not deliver a steady return, so the result is an illustration based on the rate you enter, not a forecast. Try several rates, including low ones.
Are fees, taxes and inflation included?
No. Enter a return after fees if you want to include them, and a return after inflation if you want results in today's purchasing power.
