Mortgage Calculator UK
Enter property value, deposit, interest rate and term to see your monthly payment and total cost.
How it works
We use the standard annuity formula: M = P × [r(1+r)ⁿ] / [(1+r)ⁿ−1], where P is the loan amount, r is the monthly interest rate and n is the number of monthly payments. This gives the exact repayment mortgage figure used by UK lenders.
Frequently asked questions
What is LTV and why does it matter?
Loan-to-Value is the mortgage as a percentage of the property price. Lower LTV (bigger deposit) typically unlocks better interest rates — lenders see you as lower risk.
Does this include fees and insurance?
No. The figure shows principal and interest only. Add buildings insurance, any product fees and life insurance separately.
Can I use this for buy-to-let?
Yes — the maths is identical. Enter the property value, deposit, rate and term as normal.
