Figures are computed on your device; nothing is sent anywhere.

Formula

deposit = avgMonthlyBill * monthsOfDeposit; refundable = deposit

How the calculation works

Choose the connection type, which tells you whether this is an electricity, gas or water deposit you are estimating.

Enter the average monthly bill you expect and the number of months of deposit the utility requires for your connection.

The tool multiplies the bill by the months for the deposit and marks the whole figure as refundable, since a security deposit is returned unless you owe dues.

Common mistakes

When to use it

Worked example

With an average monthly bill of 2500 Taka and a deposit of 3 months, the deposit is 7500 Taka and the whole amount is refundable when the connection closes.

Deposit ৳7,500.00
Refundable ৳7,500.00

Common questions

Is the whole deposit returned when I close the connection?

Yes, the deposit is refundable and is returned after the final bill and any dues are settled, so keep the receipt safe until that is done.
