How does the Overdraft Calculator work?

Enter the overdraft amount, duration and your bank's overdraft rate. The calculator determines the interest incurred. A comparison with an instalment loan shows whether restructuring would be worthwhile.

Key Data and Facts

Average overdraft rate 2026: approx. 11-13%. Tolerated overdraft beyond the limit: often 5-7 percentage points more. Check an instalment loan as a cheaper alternative.

Step-by-Step Guide

Step 1: Enter the amount by which you overdraw your account (e.g. 2,000 EUR). Step 2: Enter your bank's overdraft interest rate (e.g. 12.5 %). Step 3: Enter the duration of the overdraft in days (e.g. 30 days). The calculator works out the interest costs using the formula: amount × interest rate × days / 365. In addition, a comparison with an instalment loan (e.g. 6.9 % effective annual interest) is displayed. Example: 2,000 EUR overdrawn for 30 days at 12.5 % costs approx. 20.55 EUR in interest. With continuous use over 12 months it would be approx. 250 EUR — an instalment loan would cost only approx. 138 EUR.

Calculation Example

For an overdraft of 2,000 EUR, an overdraft rate of 12.5 % and 30 days: 2,000 × 0.125 × 30/365 = 20.55 EUR in interest costs. An instalment loan (6.9 %) for the same amount and period: 11.34 EUR.
