Formula

i = annualRate / 100 / 12; maturityAmount = monthlyDeposit * ((1 + i)^months - 1) / i * (1 + i); totalDeposited = monthlyDeposit * months; interestEarned = maturityAmount - totalDeposited

How the calculation works

A recurring deposit is a stream of monthly payments, and the formula compounds each payment for the months it stays in the account rather than treating the money as one lump sum.

That is why the maturity is more than the deposits plus simple interest: every instalment keeps earning until the term ends, and the earliest instalments earn the most.

Splitting the result into deposits made and interest earned makes clear how much of the final figure is your own saving and how much the bank added.

Common mistakes

Multiplying the monthly deposit by the months and adding simple interest understates the maturity, because a recurring deposit compounds each instalment.
Assuming the advertised annual rate is the effective return ignores that monthly compounding makes the real growth slightly higher than the headline rate.

When to use it

Use it before opening a DPS or recurring deposit to see the maturity you can plan around and the monthly amount you must keep paying.
Use it to compare a recurring deposit with a fixed deposit of the same total, since the recurring route usually earns less because instalments arrive over time.

Worked example

Depositing 5,000 BDT a month at 7.5 percent for 12 months gives 60,000 BDT in deposits, about 2,494.24 BDT of interest and a maturity of about 62,494.24 BDT.

Total deposited (BDT) 60,000.00

Interest earned (BDT) 2,494.24

Maturity amount 62,494.24

Common questions

Why is the interest on a recurring deposit less than on a lump sum at the same rate?

Each monthly instalment earns interest only from the month it is paid, so early deposits earn for longer and later ones for less, which lowers the average.
