Mortgage Calculator for First-Time Buyers
First-time buyers usually need more than a monthly mortgage figure. The real decision is whether the deposit, taxes, fees, and lender stress tests all fit together without leaving the move too tight from day one.
This page adapts the mortgage planning process for first-time buyers so you can start with the core mortgage number, then move quickly to the extra costs that usually catch out new buyers.
When this page is useful
- You are still working out how much deposit needs to stay liquid after fees and moving costs.
- You want to know the payment that feels comfortable, not just the biggest mortgage a lender might show.
- You need to compare saving longer against buying sooner with a smaller buffer.
Start with the base calculator
Mortgage Calculator
Start here for the main repayment estimate, then use the supporting calculators below to pressure-test affordability and upfront cash.
Example: a first-time buyer checking whether a purchase is really ready
Use a realistic scenario like this before you replace the figures with your own.
Property price
£280,000
Deposit available
£42,000
Mortgage rate and term
5.1% over 30 years
Extra cash to reserve
£8,000
The monthly mortgage may look manageable, but the better question is whether the deposit still leaves enough room for tax, legal fees, moving costs, and a sensible emergency buffer.
What to watch before you act
- !Check the payment using both the current rate and a stress-tested higher rate so the plan still works if costs move.
- !Add stamp duty, legal fees, and a moving budget before you decide the purchase is fully funded.
- !Compare the monthly payment with the full first-year housing budget, not just with current rent.
