1. What is the Monthly Payment Formula?

The monthly payment formula calculates fixed payments for amortizing loans (where payments are equal throughout the term). It's commonly used for personal loans in the UK with low interest rates.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

Where:

• \( P \) — Principal loan amount (GBP)
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• \( n \) — Number of monthly payments
• \( PMT \) — Monthly payment amount (GBP)

Explanation: The formula accounts for both principal repayment and interest charges, with earlier payments weighted more toward interest.

3. Importance of Loan Calculations

Details: Understanding monthly payments helps borrowers budget effectively and compare different loan offers. It shows the true cost of borrowing.

4. Using the Calculator

Tips: Enter the loan amount in GBP, annual interest rate (not APR), and loan term in months. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's considered a low-interest personal loan in the UK?
A: Typically under 10% APR, though rates vary based on credit score and loan term (2023 average: ~7.5% for good credit).

Q2: Does this include loan fees?
A: No, this calculates principal+interest only. Some UK loans have arrangement fees (typically 1-3% of principal).

Q3: How does loan term affect payments?
A: Longer terms reduce monthly payments but increase total interest paid. A 5-year loan at 5% costs ~13% more in interest than a 3-year loan.

Q4: Are early repayments accounted for?
A: No, this assumes fixed payments for the full term. Many UK lenders allow overpayments (typically up to 10%/year without penalty).

Q5: How accurate is this for variable-rate loans?
A: Only accurate for fixed-rate loans. Variable rates would require recalculation when rates change.
