Common questions
Are these calculators free?
Yes. Every calculator on Calc is free to use, with no sign-up and no limit on how many times you use it.
How accurate are the results?
Each calculator uses the standard formula, which is shown on its page with a worked example. Your bank or fund house may round figures or add fees differently, so treat the result as a close estimate and confirm the final number with them.
Do you save the numbers I enter?
No. The calculation happens in your browser. The amounts you type are not sent to or stored on our server.
Why are amounts shown as lakhs and crores?
The calculators are made for India, so rupee amounts use the Indian numbering format, for example ₹25,00,000 for 25 lakh.
