UK joint mortgage calculator
Estimate your joint mortgage borrowing capacity from two real take-home pay scenarios. Pick each partner's calculator below, fill in their pay, and you'll see your combined gross, combined net, and joint borrowing range at 4.0× to 4.5× combined annual gross — the typical loan-to-income range UK lenders use. Once both partners are loaded, hit Save as PDF for a mortgage-broker-ready summary including per-partner income components.

Want to know what you could really borrow?
The figure above is a rough guide based on your salary alone. A Mortgage in Principle from L&C, the UK’s favourite mortgage partner, checks your real affordability from across the market to show you what you could actually borrow.

Your home or property may be repossessed if you do not keep up repayments on your mortgage.
L&C is the exclusive mortgage partner of this calculator. If you complete on a mortgage through L&C, L&C will be paid a commission by the chosen lender. L&C will share a percentage of this commission with Take Home Network. The commission L&C receives doesn’t affect the product or rate recommended to you. Your salary figures are not shared with L&C.
Joint mortgage capacity is shown as a range — 4.0× to 4.5× combined annual gross — covering the typical loan-to-income range UK lenders use under the 2014 Mortgage Market Review rules. Some lenders cap at 4.0×, others stretch to 4.5× for higher earners or smaller deposits. Indicative only. Lenders also assess credit history, deposit size, existing debts, dependants, and stress-test affordability at higher interest rates. Joint applications typically use both incomes pooled, but lender criteria vary. Your actual joint mortgage capacity will be different.
Paste a URL into both slots to see your combined household figures. The calculator works with any URL from the takehome network — same site (e.g. two NHS staff) or different sites (e.g. an NHS nurse and a police officer).
Important — for mortgage broker reference only. Figures shown above are estimates generated by yourtakehome.co.uk/joint/ from user-entered scenarios. Always verify against the applicants' most recent payslips and the lender's specific affordability criteria.
Mortgage borrowing capacity is shown as an illustrative range of 4.0× to 4.5× combined annual gross income, reflecting the typical loan-to-income range under the 2014 Mortgage Market Review rules. Actual lender multiples vary based on credit history, deposit size, existing commitments, affordability stress tests at higher interest rates, and dependants. Some lenders count variable income (overtime, on-call, bonus, commission) at 50% or exclude it entirely — see the "Notes" column above for typical treatment per allowance.
Calculations use HMRC 2026/27 income tax, National Insurance, and student loan thresholds. Pension contributions, where shown, use the scheme rates effective on the issue date. Not financial advice.
How much joint mortgage can I get?
UK lenders typically pool both applicants' annual gross income and apply a loan-to-income multiple between 4.0× and 4.5× to estimate maximum borrowing. So two applicants on a combined gross of £80,000 might borrow £320,000–£360,000. The exact multiple depends on credit history, deposit size, existing commitments, dependants, and the lender's affordability stress test at higher interest rates. This calculator shows the indicative range against the real take-home scenarios you've configured — not a guess.
Can I get a joint mortgage with my parents?
Yes — multi-generational and joint borrower mortgages exist. The most common is a Joint Borrower Sole Proprietor (JBSP) mortgage, where a parent's income boosts borrowing capacity but they're not on the property deeds. Guarantor mortgages and family-springboard mortgages are also options. This page currently supports two applicants — paste your scenario into Slot A and your parent's into Slot B to see combined borrowing. Three- or four-applicant variants exist but are less common; the calculator architecture supports extending to N scenarios if needed.
Why use a joint mortgage calculator?
Generic mortgage calculators ask you to type in a household gross figure — but that figure depends on each applicant's specific pension scheme, allowances, London uplifts, and overtime. This page lets you build each applicant's real take-home from their actual NHS / police / fire / teacher / doctor / general salary calculator, then sums the two automatically. Useful for couples doing a joint mortgage application who want a properly-modelled figure to take to a broker, not an estimate.
How does the joint calculator work?
When you paste a share URL into Slot A or B, the joint page loads that scenario in a hidden iframe in the background. The original calculator runs as if you'd opened the URL directly, computes the take-home, and silently posts the result back to this page. Nothing is sent to a server — all calculation happens in your browser. The combined card updates as soon as both scenarios have loaded (usually within 1–2 seconds).
Can I combine two scenarios from different calculators?
Yes — you can mix NHS, doctor, fire, police, teacher and yourtakehome URLs in any combination. Common cases: NHS nurse + teacher, NHS doctor + police officer, two NHS staff, NHS + non-NHS spouse. Each calculator handles its own profession-specific maths (pension scheme, allowances, London uplifts) and the joint page just sums the results.
Does this include household deductions (rent, bills)?
Not at the joint level. This page shows combined gross + net + mortgage borrowing range. For post-tax deductions and disposable income, use the
single-person yourtakehome calculator with your combined net pay entered directly.
