The figures on this page use the values below. Open the calculator if your example salary differs.
The public mortgage calculator starts with income multiples because they are easy to compare early in a search. A single salary or combined household income can be viewed at 4x, 4.5x and 5x before moving into repayment, term, rate and monthly commitment checks.
Lenders do not use income multiples on their own. Deposit size, loan-to-value, existing debts, dependants, childcare costs, credit commitments, credit history, property type, interest-rate stress tests and lender rules can all reduce what is affordable.
PayBreakdown links mortgage affordability to take-home pay and combined household income so couples and families can compare gross borrowing ranges with monthly net income, bills, savings and repayment resilience.
Use this public mortgage affordability hub to compare simple 4x, 4.5x and 5x income multiples, then sense-check the result against deposit, debts, dependants, credit commitments, interest rates and monthly budget pressure. It is an estimate for planning only, not lender approval, regulated mortgage advice or a recommendation. Treat the output as a planning model: rate, repayment term, fees, deposit, credit commitments, balance and provider rules can change the real outcome.
PayBreakdown does not rank products, broker finance, guarantee approval, or say which mortgage, loan, credit card or repayment option is suitable. The page helps you understand affordability pressure before you review official documents or professional guidance.
Try the same repayment against a realistic monthly budget. Include fixed bills, variable spending, emergency savings, insurance, existing debts, childcare, commuting, repairs, annual costs and any expected income changes. If the result only works when every assumption is perfect, treat it as a pressure warning rather than a comfortable plan.
Provider checks can include affordability policy, credit history, existing commitments, changing rates, fees, product terms and personal circumstances that are not visible in a simple calculator. Use the estimate to spot whether a repayment looks comfortable, stretched or worth further checking, then confirm the real offer, statement or agreement with the provider before acting.
Use the visible result as a starting point, then change the assumptions that apply to your situation. For salary pages, that usually means tax year, region, tax code, pension method, student loan plan, bonus, overtime and salary-sacrifice settings. For borrowing, debt or budget pages, it means the real payment amount, term, interest rate, balance, bill timing, savings target and any expected income change. Keep the result separate from advice or approval decisions: PayBreakdown helps you model the numbers, while official sources, employer records, provider documents and professional support are still the right place for final checks. If a change is close to a threshold, rerun the calculation with a cautious higher-cost or lower-income scenario before relying on the result.

No. It is a planning estimate only. Real lender outcomes depend on affordability checks, underwriting, commitments, credit profile, property, product rules, deposit and interest-rate stress tests.
They are simple gross-income multiples used for early planning. For example, 4.5x income multiplies annual gross salary or household income by 4.5 before lender-specific affordability checks.
Yes. Existing debts, dependants, childcare, credit commitments, regular spending and the size of the deposit can all reduce the amount a lender is willing to offer.
Income multiples usually start from gross income, but monthly resilience depends on take-home pay after tax, National Insurance, pension, student loans, bills and savings commitments.
No. PayBreakdown provides neutral planning estimates and calculator links only. It does not recommend a lender, product or borrowing amount.
