The interest on balance in your PPF account is compounded annually and is credited at the end of the year. But the point to remember is that the interest calculation is done every month: the interest is calculated on lowest balances in account between 5th and the last day of the month.
Every month an interest of 2% per month for an amount of $1000 works out as follows. At the end of the first month the the amount along with interest is 1000+1000*2% = 1000(1.02) = 1020 which is $1000+ interest $20. At the end of the 2nd month he has to pay 1020(1.02) = 1000(1.02)^2 = $1040*4 .= $1000 + interest $ 40.4.
