How accurate are these calculators?
They are for planning. Small savings interest rates are notified by the Ministry of Finance and revised every quarter, and statutory limits change with amendments — so a projection made today will not match the final figure exactly. Where a calculator asks you to enter a rate, check the current quarter on the official source linked on that page before relying on the result.
