India Post, National Savings Recurring Deposit Account - maturity formula M = R[(1+i)^n - 1]/(1 - (1+i)^(-1/3))
R is the monthly instalment, i the quarterly rate (annual rate / 4) and n the number of quarters. The 1/3 exponent is the one-month share of a quarter, which is what makes each instalment earn only its remaining months of interest.
Future value of a compound-interest deposit, A = P(1 + i)^t, summed over the instalments
The engine evaluates the instalment sum directly, which reproduces the published closed form exactly and also covers monthly, half-yearly and annual compounding.
