Formula Used

The monthly payment is calculated using the standard loan payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount (your credit card balance) i = Monthly interest rate (APR/12/100) n = Number of payments (repayment term in months)

This formula accounts for the interest you'll pay over the repayment period.

Worked Example

Let's say you have a credit card balance of £2,000 with an APR of 18.9% and you want to pay it off in 12 months.

Monthly interest rate = 18.9%/12 = 1.575%
Using the formula:
M = £2000 [ 0.01575(1 + 0.01575)^12 ] / [ (1 + 0.01575)^12 - 1 ] M ≈ £173.34
Total interest paid = £173.34 × 12 - £2000 = £200.08

Your monthly payment would be approximately £173.34, with a total interest charge of £200.08.

UK-Specific Considerations

The UK has specific regulations regarding credit card interest rates and repayment terms:

Interest rates are capped at 5% for purchases and 0% for balance transfers (under the Consumer Credit Act 1974)
Minimum payment requirements are set by the Financial Conduct Authority (FCA)
Some cards offer 0% balance transfer deals for a limited period

Note: Always check your credit card agreement for specific terms and conditions that may apply to your account.

Frequently Asked Questions

What is the difference between APR and interest rate?: APR (Annual Percentage Rate) is the total cost of credit including fees and interest, while the interest rate is just the interest portion. APR is always higher than the interest rate.
How does changing the repayment term affect my monthly payment?: A longer repayment term will result in a lower monthly payment but higher total interest charges. A shorter term means higher monthly payments but less total interest paid.
What happens if I only pay the minimum monthly payment?: If you only pay the minimum, you'll pay more in interest over time. It's generally better to pay more than the minimum to reduce the principal balance faster.
Can I pay off my credit card balance in full each month?: Yes, paying your balance in full each month will avoid interest charges entirely, but you'll need to have enough funds available each month.
What should I do if I can't make my minimum payment?: Contact your credit card issuer immediately to discuss payment arrangements. Missing payments can lead to higher interest rates or account closure.
