How RD interest is worked out

In a recurring deposit you pay the same amount every month. Banks add interest every quarter. Each instalment earns interest for the months it stays in the account:

Maturity = Σ R × (1 + r ÷ 400)(months left ÷ 3)

R is the monthly deposit and r the yearly rate in percent. This gives the same answer as the formula banks print, M = R × ((1 + i)n − 1) ÷ (1 − (1 + i)−1/3), with i = r ÷ 400 and n the number of quarters.

RD interest is taxed at your slab rate, and banks deduct TDS above a yearly limit. A late instalment can attract a small penalty.

Questions

Is a Post Office RD the same?

The Post Office RD runs for 5 years and also adds interest every quarter, so this calculator works for it. Use the current Post Office rate.

FD or RD?

An FD earns more if you already have the money, because all of it earns interest from day one. An RD suits saving from your monthly income.
