Methodology & Logic
How the Recurring Deposit Calculator works
Estimate maturity value from a fixed monthly RD deposit. Below is the exact mathematical or algorithmic model used by this investment utility, along with its key operating assumptions.
Core Formula / Logic
Maturity = R × [(1 + i)ⁿ − 1] ÷ [1 − (1 + i)^(−1/3)], where R is the monthly deposit, i = annual rate ÷ 4 and n = number of quarters (deposits at the start of each month, interest compounded quarterly, as Indian banks do).Step-by-step workflow
- Set your starting capital, rate, or tenure in the Recurring Deposit Calculator controls (or pick a quick INR benchmark preset).
- The calculation engine applies Maturity = R × [(1 + i)ⁿ − 1] ÷ [1 − (1 + i)^(−1/3)], where R is the monthly deposit, i = annual rate ÷ 4 and n = number of quarters (deposits at the start of each month, interest compounded quarterly, as Indian banks do). on every change and separates principal from compounded gains or interest.
- Inspect the visual chart breakdown and adjust sliders to stress-test lower returns, higher inflation, or extra prepayments.
