Calculate Your Overdraft Costs
What is an Overdraft?
An overdraft is a form of credit that allows you to spend more money than you have in your current account. When you go overdrawn, you’re essentially borrowing money from your bank, and they’ll charge you interest and fees for this service.
Types of Overdrafts
- Arranged Overdraft: Pre-agreed with your bank, with set limits and interest rates
- Unarranged Overdraft: Going overdrawn without prior agreement, typically with higher charges
Important: Since April 2020, UK banks can no longer charge daily or monthly fees for overdrafts. They can only charge interest, making costs more transparent and often cheaper.
How Overdraft Interest Works
Overdraft interest is calculated daily on the amount you’re overdrawn and added to your account monthly. The interest rate is typically shown as an EAR (Effective Annual Rate).
Interest Calculation Formula
Daily Interest = (Overdraft Amount × Annual Rate) ÷ 365
Total Cost = Daily Interest × Number of Days
| Bank Type | Typical Interest Rate | Interest-Free Amount |
|---|---|---|
| Digital Banks | 15% – 25% EAR | £0 – £500 |
| Building Societies | 25% – 35% EAR | £25 – £250 |
| High Street Banks | 35% – 40% EAR | £0 – £250 |
Overdraft Costs by Bank
Different UK banks offer varying overdraft rates and terms. Here’s a comparison of major providers:
| Bank | Interest Rate | Interest-Free Amount | Monthly Cap |
|---|---|---|---|
| HSBC | 39.9% EAR | £25 | £20 |
| Nationwide | 39.9% EAR | £50 | No cap |
| Starling Bank | 15%, 25%, 35% EAR | £0 | No cap |
| First Direct | 39.9% EAR | £250 | No cap |
Note: Interest rates and terms can change. Always check with your bank for current rates before making financial decisions.

Frequently Asked Questions
What happens if I go over my overdraft limit?
If you exceed your arranged overdraft limit, you’ll enter an unarranged overdraft. This typically incurs the same interest rate but may have additional restrictions. Most banks now have monthly caps on unarranged overdraft charges.
Can banks refuse overdraft applications?
Yes, banks assess overdraft applications based on your credit score, income, and banking history. They’re not obligated to provide an overdraft facility.
How often is overdraft interest charged?
Interest is calculated daily but typically added to your account monthly. You’ll see these charges on your monthly statement.
Can I reduce my overdraft limit?
Yes, you can request to reduce or remove your overdraft limit at any time. However, you’ll need to clear any existing overdraft balance first.
Do overdrafts affect my credit score?
Regular use of your overdraft facility within agreed limits typically won’t harm your credit score. However, going into unarranged overdraft or missing payments can negatively impact your credit rating.
Overdraft Regulations in the UK
The Financial Conduct Authority (FCA) introduced significant changes to overdraft regulations in April 2020 to make charges fairer and more transparent.
Key Changes Include:
- Removal of daily and monthly overdraft fees
- Simple annual interest rate charging
- Same rate for arranged and unarranged overdrafts
- Improved transparency in overdraft costs
- Better protection for vulnerable customers
Consumer Protection: Banks must now provide clearer information about overdraft costs and offer better support for customers in financial difficulty.
