RD formula
Each instalment earns compound interest from the month it is deposited until maturity. With quarterly compounding the maturity value is M = R × [(1 + i)ⁿ − 1] ÷ [1 − (1 + i)^(−1/3)], where R is the monthly deposit, i the quarterly rate (yearly rate ÷ 400) and n the number of quarters.
For example, ₹5,000 a month for 5 years at 7% gives about ₹3.60 lakh: ₹3,00,000 of deposits and roughly ₹60,000 of interest. Early instalments earn the most because they stay invested longest.
RD or FD?
| Recurring deposit (RD) | Fixed deposit (FD) | |
|---|---|---|
| How you invest | A fixed amount every month | One lump sum at the start |
| Best for | Saving from a monthly salary | Money you already have |
| Interest earned | Lower for the same total, because later instalments earn for less time | Higher, as the whole amount earns from day one |
| Tax | Interest taxed at your slab; TDS above the yearly limit | The same |
