Overdraft Interest Calculator – Estimate Your OD Interest

An overdraft (OD) facility lets you withdraw more than the balance in your account, up to an approved limit. Interest is usually charged only on the amount you actually use and for the number of days you use it.

Use the CibilBazaar Overdraft Interest Calculator to estimate the interest you will pay for a given overdrawn amount, number of days and interest rate.

How Is Overdraft Interest Calculated?

Overdraft interest = Amount overdrawn × Interest rate ÷ 365 × Number of days. The calculator also shows the interest amount per day.

Figures are rounded to the nearest rupee. Actual charges may also include processing fees, GST or minimum interest as per your bank.

What Affects Your Overdraft Interest

Amount Used

Interest grows with the amount you draw, so using less of the limit reduces the cost.

Number of Days

Interest is counted for each day the amount remains overdrawn, so repaying early saves interest.

Interest Rate

A higher annual rate directly increases the daily and total interest.

Other Charges

Processing fees, GST and minimum interest may apply on top of the interest.

Frequently Asked Questions (FAQs)

1. What is an overdraft facility?

An overdraft facility allows you to withdraw money beyond your account balance up to a limit approved by the bank.

2. How is overdraft interest calculated?

Interest is calculated as the amount overdrawn multiplied by the annual rate, divided by 365 and multiplied by the number of days utilised.

3. Is interest charged on the full limit or only the amount used?

Overdraft interest is usually charged on the amount you actually use, but this depends on your bank's terms. Confirm with your lender.

4. Are there other charges besides interest?

Banks may charge processing fees, GST or minimum interest in addition to the interest calculated here.
