Mortgage Formula (How It Is Calculated)
Mortgage calculations are based on loan amount, interest rate, and repayment term.
1. Loan Amount
Loan Amount = Property Price – Deposit
2. Monthly Mortgage Repayment (Simplified)
Monthly Payment = (Loan Amount × Interest Rate ÷ 12) adjusted over mortgage term
Example:
- Property price: £300,000
- Deposit: £60,000
- Loan amount: £240,000
- Interest rate: 5%
Estimated monthly repayment: £1,300–£1,400 (approx.)
