Mortgage Calculator UK

Buying a home or investing in property is one of the biggest financial decisions you will make. The Mortgage Calculator UK by Accotax helps you estimate your monthly mortgage repayments, total interest costs, and overall affordability in just a few seconds. Whether you are a first-time buyer, moving home, or investing in property, understanding your mortgage commitment in advance is essential for smart financial planning.

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.)
