What Recurring Deposit Calculator does, with a checked example
A recurring deposit turns fixed monthly installments into a single maturity payout: you deposit the same amount every month, the balance compounds at the quoted annual rate, and you collect everything at the end of the tenure. This calculator takes the monthly deposit, the interest rate, and the tenure, and returns the maturity value plus the interest earned. The surprise is how small the interest portion is. Interest is not earned on the full maturity sum: the first installment compounds for the whole tenure while the last earns only one month, so the total interest lands near what half the deposited amount would earn.
Worked example
A concrete input and expected output from the current implementation.
Input
Monthly deposit: 1000 | Annual interest rate: 7% | Tenure: 24 months
->
Expected output
Maturity value 25,820 after 24 months, made up of 24,000 deposited plus 1,820 interest, using quarterly compounding (the standard convention for Indian recurring deposits).
Each of the 24 installments compounds at 7% / 4 = 1.75% per quarter for the quarters it stays in the account; summing the future values of all installments gives 25,819.8, which rounds to 25,820, and the interest is that minus the 24,000 deposited = 1,820. With monthly compounding the same inputs give about 25,833 instead, so the compounding convention matters.
