Mortgage deposit calculator

Set a deposit savings target for a home you have in mind. Compare what you already have with what you could save each month.
A planning estimate, not a lender decision.

A savings target, not an eligibility decision

Plan a deposit that works for your budget

Choose a property price and the deposit percentage you would like to explore. This calculator shows your target in pounds, the gap after your existing savings, and either how long regular saving might take or what you would need to save each month by a chosen date. It does not set a lender's minimum deposit or check whether you can borrow the balance.

Use the price you are considering, even if you are still looking.

This is your planning choice, not a universal lender requirement.

Leave money needed for other buying costs out of this figure.

Enter this to see an approximate time to target.

If you enter both, we show the monthly amount needed by the date and compare it with your planned saving.

Assumes your savings and property price stay unchanged, with no savings interest, fees, tax or price growth. Figures are rounded for planning.

What the result means

Your chosen deposit

The percentage you enter is applied to the price you enter. For example, a 10% target on a £300,000 home is £30,000. This is an illustration, not an amount a lender has approved or required.

The savings gap

We subtract the amount you have already set aside. The gap is only for the deposit; keep a separate budget for legal work, surveys, tax where due, moving and other costs.

Time or monthly saving

A regular monthly amount gives an approximate number of whole months. A target date gives the monthly amount needed from now. Savings interest and changing house prices are excluded.

Before you set a deposit target

1. Check the wider budget

A larger deposit could reduce the mortgage amount, but your deposit is only one part of a purchase. Use the stamp duty calculator if buying in England or Northern Ireland, and check the relevant property tax rules elsewhere in the UK.

2. Check borrowing and payments

Your income, commitments, credit record, property and the lender's current criteria affect what may be available. Explore a payment scenario with our repayment calculator; it is not an affordability or eligibility decision.

3. Discuss your circumstances

If your income is self-employed, variable or newly established, your evidence and the way a lender assesses it may matter as much as the cash you have saved. Read our self-employed mortgage guide or ask for a case-specific discussion.

From savings plan to mortgage application

When you are ready to seek advice, tell us your approximate price range, deposit available, mortgage purpose and how you earn. We can explain what information may be useful before an application, including income evidence for self-employed applicants. Lender criteria and available products change; an adviser must check the current position for your circumstances. A savings calculation cannot guarantee a mortgage offer.

For broader planning, visit our mortgage calculators or read the first-time buyer mortgage guide. For independent budgeting guidance, see MoneyHelper's deposit guide and its buying-cost checklist.

Mortgage deposit calculator questions

Does this tell me the minimum deposit a lender will accept?

No. The percentage is a target you choose. Deposit criteria depend on the mortgage product, property and your circumstances, and can change. Ask an adviser to check current lender options before relying on a particular amount.

Does a larger deposit mean I can borrow the rest?

No. A lender will still assess affordability, credit, the property and appropriate income evidence. This tool only works out a savings target.

What if I already have enough saved?

The savings gap is shown as £0. Keep a separate allowance for other buying costs and check your borrowing options before committing to a purchase.

Can I include a gifted deposit?

You can include money you expect to have available for the deposit, but tell your adviser where it will come from. A lender may ask for evidence and have conditions about gifts; do not treat an expected gift as confirmed until it is documented.

Can a self-employed buyer use this calculator?

Yes, to plan a deposit. It does not assess self-employed income or decide eligibility. Our self-employed mortgage advice page explains how business structure and income evidence can affect an application.
