How this was calculated
Monthly profit = ৳10,00,000 × 11.5% ÷ 12 = ৳9,583
Source tax at 10% = ৳958; ৳8,625 a month in hand
Excise duty ৳500 a year × 5 years = ৳2,500
Total net = ৳8,625 × 60 months − duty = ৳5,15,000
If the final rate differs, the monthly profit is ৳8,250 to ৳9,000

Monthly profit formula (at the provisional rate)
Monthly profit = deposit × provisional rate ÷ 12
Source tax is deducted from each month’s profit. Excise duty is charged once a year on the deposit balance. The deposit is returned at maturity.

What to know in Bangladesh
Rates differ by bank: the table is an example; check your bank’s rate sheet.
Senior citizen rates: many banks pay older depositors a slightly higher rate; confirm the age condition with the bank.
Source tax: 10% of each month’s profit, 15% without PSR.
Excise duty: once a year when the deposit is above ৳4 lakh.
More: planning a monthly income
If you’ll rely on this for monthly expenses, plan with the after-tax amount, and remember the profit is at the provisional rate — if the final rate is lower, the adjustment may reduce it slightly. Splitting across banks can lower both the excise duty slab and the risk.
Frequently asked questions
What is a monthly profit scheme?
A lump sum stays deposited for a fixed term, and the profit earned under Mudaraba is paid into your account every month. The deposit is returned at maturity. It is popular with retirees and anyone who wants a regular monthly income.
How much monthly profit does ৳10 lakh earn?
At an 11.50% provisional rate, ৳9,583 a month before tax and ৳8,625 after 10% source tax. At the 11.70% senior citizen rate, ৳8,775 after tax. Because the balance is in the ৳5–10 lakh slab, ৳500 excise duty is also deducted each year.
Does the monthly profit change later?
Monthly profit is paid at the provisional rate. After the bank declares the final rate for the year, any difference is adjusted, so the total may end up slightly higher or lower.
Savings certificate or monthly profit scheme?
Savings certificates usually pay more but have strict purchase limits and conditions. Monthly profit schemes are more flexible, and depositors who want Shariah-compliant investment choose them too. Compare the same amount in both calculators.
What if I withdraw before maturity?
Many banks then recover part of the profit already paid or recalculate at a lower rate. Rules differ by bank, so check the terms.
