1. What is the Loan Interest Calculator?

The Loan Interest Calculator calculates the total interest paid over the life of a loan in the UK. It helps borrowers understand the true cost of borrowing by showing how much extra they'll pay beyond the principal amount.

2. How Does the Calculator Work?

The calculator uses the loan interest formula:

Where:

• \( PMT \) — Monthly payment amount in GBP
• \( n \) — Loan term in months
• \( PV \) — Principal loan amount in GBP

Explanation: The formula calculates the total amount paid over the loan term and subtracts the principal to determine the interest paid.

3. Importance of Loan Interest Calculation

Details: Understanding total interest helps borrowers compare loan offers, make informed financial decisions, and plan their budgets effectively.

4. Using the Calculator

Tips: Enter your monthly payment amount in GBP, loan term in months, and principal amount in GBP. All values must be positive numbers.

Q3: Can I use this for mortgage calculations?

Q5: Does this work for interest-only loans?
A: No, this calculator is designed for repayment loans where both principal and interest are paid monthly.
