Monthly investment
Start with monthly investment, because it shapes the entire result and usually has the biggest absolute impact on the final output. In practice, it works best to test multiple scenarios instead of relying on a single estimate.

How it works
What this sip calculator is showing you
Investment planning becomes clearer when you can separate what comes from your own contributions and what comes from growth. This SIP Calculator is designed to help you see how time, return assumptions, and contribution size shape the result.
That makes it easier to use the calculation as a planning tool instead of treating it as a prediction. Small differences in time horizon or return assumptions can create large changes in future value, especially across longer periods.
Calculation method
Future value is calculated as a series of monthly contributions compounded at the expected monthly return rate.
Input planning
Inputs that matter most
Expected annual return (%)
Review expected annual return (%) carefully, since even a small change here can shift affordability, growth, or tax burden more than expected. In practice, it works best to test multiple scenarios instead of relying on a single estimate.
Investment period (years)
Investment period (years) adds planning context to the result and helps you compare short-term comfort with long-term cost or value. In practice, it works best to test multiple scenarios instead of relying on a single estimate.
Planning guidance
How to read the result well
A future-value estimate is usually best read as a planning range, not a promise. The main question is whether the current contribution level and time horizon move you meaningfully toward the target you care about.
If the projection feels too low, the highest-leverage changes are often starting earlier, contributing more consistently, or extending the time horizon rather than chasing unrealistic return assumptions.
- Use a conservative return assumption first, then compare it with a more optimistic scenario.
- Check whether increasing contributions or extending the time horizon has the larger impact for your goal.
- Keep the estimate connected to a real target such as retirement, education, or emergency reserves.
Worked example
A sample scenario before you enter your own numbers
Many people understand a calculator faster when they can see one complete example first. The summary below uses the default assumptions shown in the form, so you can get a feel for the output before testing your own situation.
Maturity value
$208,962.13
Total invested
$90,000.00
Estimated returns
$118,962.13
The result assumes your contribution is invested every month and earns a steady annualized return throughout the period.
