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

2. How Does the Calculator Work?

The calculator uses the mortgage payment 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 payment (GBP)
\( P \) — Loan principal amount (GBP)
\( r \) — Annual interest rate (decimal)
\( t \) — Loan term in years
