How does the PPF calculator work out maturity?
Each year the tool adds your deposit to the balance, applies the interest rate to the whole balance and adds that interest at year end, so interest compounds once a year. With ₹1,50,000 a year at 7.1%, year 1 earns ₹10,650 and closes at ₹1,60,650. Year 2 adds another ₹1,50,000 and earns ₹22,056 on ₹3,10,650. After 15 years the balance is ₹40,68,209: ₹22,50,000 of deposits and ₹18,18,209 of interest. By year 15, the interest credited in that one year, ₹2,69,695, is more than that year's ₹1,50,000 deposit.
The maturity value scales with the deposit, so ₹50,000 a year on the same terms gives exactly a third of that total, ₹13,56,070. Keeping ₹1.5 lakh going through five-year extensions gives ₹66,58,288 at 20 years and ₹1,03,08,015 at 25 years. The tenure slider accepts any whole number from 15 to 50, so pick 20, 25 or 30 to match a real extension.
Does the date you deposit in PPF matter?
It does, because PPF interest is calculated monthly on the lowest balance between the 5th and the last day of each month and credited at the end of the financial year. The calculator treats each year's deposit as sitting in the account for all 12 months, which matches paying the full amount on or before 5 April.
Paying ₹12,500 by the 5th of every month puts in the same ₹1.5 lakh over the year, yet earns about ₹5,769 in the first year against the ₹10,650 in the table. Money deposited after 5 March earns nothing until the next financial year. If you deposit monthly or late in the year, expect a maturity value below the one on screen.
What does the PPF calculator assume?
One rate applies to every year, so test a range: at 6.6% the 15-year total is ₹38,96,480 and at 7.6% it is ₹42,48,290. Deposits stay the same each year, within the scheme's limits of ₹500 to ₹1.5 lakh per financial year. Extensions are modelled with deposits only. If you stop paying in after 15 years, the ₹40,68,209 balance left to grow at 7.1% for five more years reaches about ₹57,32,587, against ₹66,58,288 when deposits continue.
For a single lump sum at a fixed rate, the Compound Interest Calculator is the closer fit, and the FD Calculator handles bank deposits with monthly, quarterly, half-yearly or yearly compounding.
