Tenure (years)

How to use this tool

1. Enter the amount you deposit every month into your DPS.
2. Enter the yearly profit rate your bank quotes and the tenure in years.
3. Press Calculate Maturity — see the final value, total deposited and total profit.

Example

Deposit 5,000 ৳ every month at 8% yearly profit for 5 years: maturity ≈ 369,800 ৳. You deposited 300,000 ৳ yourself — the scheme earned you about 69,800 ৳ extra.

The formula

Maturity = M × [((1+i)^n − 1) ÷ i] × (1+i), where i = yearly rate ÷ 12, n = years × 12

What the result means

This is the standard future-value formula for a monthly savings scheme where each deposit is made at the start of the month and profit compounds monthly. The "profit earned" figure is the real magic of DPS: your money earns on money you deposited earlier, so the last year alone adds far more profit than the first. Compare it with simply keeping cash at home — that difference is what the scheme pays you for your discipline.

Frequently asked questions

Is this the same figure my bank will pay?

The formula is the standard reducing-balance method, but each bank sets its own rate and some apply slightly different day-count or instalment-day rules. Use this to plan and compare, then confirm the final figure with your bank's DPS schedule.

What rate should I enter?

Enter the exact yearly rate your bank quotes for its Deposit Pension Scheme. Rates differ between banks and change with the market — check your bank's current DPS rate before deciding.

Does it work for Islamic banks?

Yes — enter the expected profit rate instead of interest. The math of monthly compounding profit works the same way for comparison purposes.

What if I set the rate to 0?

You will see the pure total of your deposits with zero growth — a useful baseline showing exactly how much of the maturity value is your own money.

Is DPS profit taxable?

Tax rules on deposit income change from year to year — check the current NBR rules or ask your bank before you plan around the maturity value.
