About the SIP Calculator

The SIP Calculator projects the maturity value of a monthly Systematic Investment Plan, showing invested amount against estimated returns. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Setting a monthly amount to reach a target corpus.
  • Comparing a flat SIP with a step-up SIP.
  • Explaining compounding to a first-time investor.

The maths behind it

This tool uses M = P × (((1 + i)ⁿ − 1) ÷ i) × (1 + i), where i is the monthly rate and n the number of instalments. Every intermediate value is shown on screen, so the result can be checked by hand.

Expected return is an assumption, not a promise. Market-linked investments can and do fall. Run the numbers again at a lower rate to see the downside case.

Frequently asked questions

Are there any usage caps on the SIP Calculator?
There is no cost and no cap. The SIP Calculator is not a demo of a paid product, so nothing is held back or watermarked.
Is the SIP Calculator safe to use with private information?
No. The SIP Calculator runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
What formula does the SIP Calculator use?
It uses M = P × (((1 + i)ⁿ − 1) ÷ i) × (1 + i), where i is the monthly rate and n the number of instalments. The full working is printed under the result, so you can follow every step rather than trusting a black box.
What do people use the SIP Calculator for most?
Typical uses: setting a monthly amount to reach a target corpus. Comparing a flat SIP with a step-up SIP. Explaining compounding to a first-time investor. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
What do people usually get wrong here?
Expected return is an assumption, not a promise. Market-linked investments can and do fall. Run the numbers again at a lower rate to see the downside case.
Is the number rounded?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
