The mortgage repayment formula calculates the fixed monthly payment required to repay a loan over a specified term, including both principal and interest components. This formula is widely used for mortgage and loan calculations.

2. How Does the Calculator Work?

The calculator uses the mortgage repayment formula:

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

Where:

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