Understanding what you can borrow and what a mortgage will cost is the starting point for any property decision. Our calculators are built specifically for contractors, with income inputs that reflect how you actually earn rather than assuming a fixed monthly salary.
Use them for quick estimates to inform your thinking, then speak to an adviser for a precise figure based on your full circumstances. Calculator results are indicative only your actual borrowing will depend on your credit history, outgoings, the lender’s current criteria and a full affordability assessment.
The most important calculator for most contractors. Enter your day rate and working weeks, and we show you what contractor-friendly lenders at three tiers conservative, standard and specialist would typically offer.
The conservative figure reflects lenders using standard 4x income multiples. The standard figure reflects specialist contractor lenders using 4.5x day rate annualisation. The specialist figure reflects the best-case outcome with professional mortgage lenders or enhanced multiples, up to 5.5x.
These are indicative ranges. The precise figure depends on your credit profile, existing commitments, deposit size and the specific lender. Speak to an adviser to turn an indicative figure into a confirmed mortgage in principle.
Enter your loan amount, interest rate and mortgage term to see your estimated monthly repayment. Useful for budgeting and for comparing the cost of different rate or term combinations.
For buy to let applicants, we also show the interest-only monthly payment, which is the basis on which BTL affordability is assessed by most lenders.
Stamp Duty Land Tax (SDLT) in England and Northern Ireland, Land and Buildings Transaction Tax (LBTT) in Scotland, and Land Transaction Tax (LTT) in Wales are all calculated differently. Our stamp duty calculator covers all three jurisdictions and includes the 3% additional dwellings surcharge for second home and buy to let purchases.
Remember that from April 2025, the stamp duty thresholds for first-time buyers and standard residential purchases returned to their previous levels following the temporary increases introduced in 2022. Our calculator reflects current thresholds.
Loan to value — the mortgage amount as a percentage of the property value — determines which products you can access and at what rate. Lower LTV means lower risk for the lender, which typically means better rates for you.
Understanding your LTV is particularly important for remortgage decisions. If your property has increased in value since purchase, your LTV may have fallen significantly, opening up better rate bands. Our LTV calculator works for both purchase and remortgage scenarios.
For buy to let investors, rental yield is a key measure of a property’s income potential. Gross yield is the annual rent as a percentage of the purchase price. Net yield accounts for voids, management fees, maintenance and other costs.
Our rental yield calculator shows both gross and net yield based on your inputs, helping you compare investment properties on a consistent basis. Most BTL lenders require a minimum rental income coverage ratio — typically 125% to 145% of the monthly mortgage payment — which our calculator also shows.
The calculators provide indicative figures based on standard lender criteria and typical income multiples. They are designed to give you a useful starting point for planning and decision-making, not a guaranteed mortgage offer. Actual borrowing will depend on a full affordability assessment, credit check, property valuation and the specific lender’s current criteria.
Different lenders use different methods to assess contractor income, and different income multiples. The conservative figure reflects what a standard lender using SA302 or PAYE assessment might offer. The standard figure reflects what specialist contractor lenders using day rate annualisation typically offer. The specialist figure reflects the best outcome with professional mortgage lenders offering enhanced multiples. Speaking to an adviser tells you which tier is realistic for your specific circumstances.
No — all calculators are free to use without registration. No credit check is carried out and no data is shared with lenders. The WhatsApp button below the borrowing calculator sends your result directly to an adviser if you want to take the next step.
