1. What is the Loan Payment Formula?

The loan payment formula calculates the fixed monthly payment required to repay a loan over a specified term. It accounts for the principal amount, interest rate, and loan duration to determine the consistent payment amount.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

\[ PMT = P \times \frac{r}{12} \times \frac{(1 + \frac{r}{12})^{12 \times t}}{(1 + \frac{r}{12})^{12 \times t} - 1} \]

Where:

\( PMT \) — Monthly payment (GBP)
\( P \) — Loan principal (GBP)
\( r \) — Annual interest rate (decimal)
\( t \) — Loan term in years

Explanation: The formula calculates the fixed monthly payment needed to fully amortize a loan over its term, accounting for compound interest.

3. Importance of Loan Calculation

Details: Accurate loan payment calculation is essential for financial planning, budgeting, and comparing different loan options. It helps borrowers understand their repayment obligations before committing to a loan.

4. Using the Calculator

Tips: Enter the loan amount in GBP, annual interest rate as a percentage, and loan term in years. All values must be positive numbers with the term typically between 1-30 years for most loans.

A: No, this calculator provides the base monthly payment excluding any additional fees, insurance, or charges that may be associated with a loan.

Q2: What is compound interest?
A: Compound interest means interest is calculated on both the initial principal and the accumulated interest from previous periods.

Q3: How does loan term affect monthly payments?
