FAQ

How do I calculate fixed deposit interest in Sri Lanka?

Enter the deposit amount and tenure, then the calculator estimates profit, maturity value, and monthly income where relevant using the bank-rate data shown on the page.

Can I compare fixed deposit rates across banks here?

Yes. The page compares bank options for the selected tenure and also shows the wider rate table below the calculator.

Does this fixed deposit calculator include withholding tax?

Yes. You can switch withholding tax on and apply the selected rate so the result reflects a net-interest scenario instead of a gross-interest one.

Can I estimate monthly income from a fixed deposit?

Yes. Where a matching monthly-interest option exists, the result highlights the estimated monthly income alongside maturity-focused returns.
