Home loan calculators

Work out your buying costs or compare ways to repay your loan. Free to use, with no contact details required.

How much cash do you need to buy?

Estimate your deposit, stamp duty and fees. Save the figures and come back when the property price or quotes change.

Calculate buying costs

Keep moving costs and your cash buffer separate. Final costs and loan approval still need checking.

What could you change about your repayments?

Compare an offset, extra repayments or a lump sum. Save a plan to revisit with your next loan statement.

Compare repayments

An estimate, not your lender's exact interest calculation. Check product fees, offset availability and repayment rules.

Other tools

Borrowing Power Lab

See why three fictional lender types give different estimates from the same income and expenses.

An illustration of lender differences, not a live borrowing limit or named lender's policy.

Compare borrowing estimates

Buy first or sell first?

Compare the timing, peak debt and costs of selling first, aligned settlements, bridging or keeping both homes.

Bridging availability, valuations, contract terms and tax outcomes need separate advice.

Compare buying and selling

Help to Buy Calculator

Explore a shared-equity purchase and compare the estimated loan and repayments with a standard purchase.

Check current scheme rules and property limits. An estimate doesn't confirm eligibility or an available place.

Before using an estimate

Each tool explains its assumptions and links to the sources it uses. Check dates and current rules before relying on a result.

These tools provide general information and simplified estimates only. They don't take into account your objectives, financial situation or needs and aren't financial, investment, tax, legal or credit advice. A result is not an approval, quote or personal recommendation. Lender assessment, government rules, costs and property acceptance depend on your circumstances and can change.
