If you’re a contractor working on a day rate, calculating how much you could borrow for a mortgage isn’t always as straightforward as looking at your payslips or latest tax return.
Some mortgage lenders can assess contractors based on their day rate, rather than relying solely on conventional employed or self-employed income calculations. For contractors with a high day rate, this can make a significant difference to the income lenders use to assess mortgage affordability.
How is a day rate mortgage calculated?
Specialist contractor-friendly lenders may calculate your annualised income using your current contract rate.
A commonly used calculation is:
Daily rate × 5 days × 46–48 working weeks = annualised contractor income
The number of weeks used varies between lenders. Some may use 46 weeks, while others may use 48 weeks or their own contractor affordability criteria.
For example, if you earn £500 per day and a lender uses 46 working weeks:
£500 × 5 × 46 = £115,000 annualised income
Rather than assessing you purely on the salary you draw from your limited company or the figures on your payslips, an appropriate lender may therefore use an annualised income of £115,000 when assessing affordability.
Example day rate mortgage calculations
| Contractor day rate | 46-week calculation | 48-week calculation |
| £300 | £69,000 | £72,000 |
| £400 | £92,000 | £96,000 |
| £500 | £115,000 | £120,000 |
| £600 | £138,000 | £144,000 |
| £750 | £172,500 | £180,000 |
These figures represent the annualised income a lender could use for its affordability assessment, not necessarily the amount you can borrow.
How much can I borrow on a day rate mortgage?
Once a lender has calculated your annualised contractor income, it will use that figure as part of its wider affordability assessment.
There isn’t one universal income multiple that tells every contractor exactly how much they can borrow. The amount available will depend on the lender and factors including:
- Your deposit
- Existing debts and credit commitments
- Regular expenditure
- Dependants
- Credit history
- Mortgage term
This means two contractors earning the same £500 day rate could be offered different maximum mortgage amounts.
The important first step is establishing which lenders will recognise your contractor income appropriately.
Why can a day rate calculation make a difference?
Contractors don’t always fit neatly into the standard income categories used by mortgage lenders.
For example, you might operate through a limited company and pay yourself a relatively modest salary. A lender relying on that salary alone may not get the clearest picture of your current earning capacity.
A contractor-friendly lender may instead consider your current contract and day rate. For a contractor on £600 per day, the 46-week calculation would be:
£600 × 5 × 46 = £138,000
That £138,000 figure may provide a more relevant representation of current annualised earnings than looking only at a comparatively low PAYE salary.
Whether a lender uses this method depends on its criteria and your circumstances.
Mainstream vs specialist contractor mortgage assessments
One of the biggest differences contractors encounter is how lenders interpret their income.
A conventional assessment may focus on payslips, salary and dividends, company accounts or previous taxable income. Those documents can still be relevant, but they don’t always reflect how a contractor currently earns.
Lenders with contractor-specific criteria may instead be prepared to look at your current contract value and day rate.
A lender’s approach to assessing your income will depend on how you work and its individual criteria. For example:
- Standard employed applicants: Lenders typically review salary and payslips to assess income.
- Limited company directors: Income may be assessed using salary, dividends and/or company accounts.
- Self-employed applicants: Lenders may consider taxable income from previous years.
- Contractors assessed on their day rate: Contractor-friendly lenders may use your current day rate and contract details to calculate annualised income.
For contractors, this difference can be important, as a day-rate calculation may provide a more accurate picture of current earning capacity than a standard income assessment.
What else do lenders consider?
Your day rate is important, but it isn’t the only factor.
Depending on the lender, they may also consider how long you’ve been contracting, the time remaining on your current contract, your history of renewals, gaps between contracts and your experience within the industry.
Some lenders may also consider contractors who have only recently moved from permanent employment, particularly if they continue to work in the same profession. Your IR35 position and how you’re paid can also influence how your income is assessed.
Criteria vary considerably between lenders, so being declined by one doesn’t necessarily mean another will reach the same decision.
Why choosing the right lender matters
For contractors, mortgage affordability isn’t only about how much you earn. It’s also about how the lender calculates your income.
A lender using salary or historic taxable income could arrive at a very different affordability figure from one prepared by annualising your current day rate. That makes lender selection particularly important.
At ASF, we understand how different lenders assess contractor income and can identify lenders whose criteria align with your working arrangements.
Rather than trying to make contractor income fit a standard employed-mortgage assessment, we can look at how your day rate, contract, and wider circumstances could be assessed by suitable lenders.
Day rate mortgage FAQs
What is the formula for calculating a contractor’s day-rate income?
A common calculation is:
Daily rate × 5 days × 46–48 weeks = annualised income
For a £400 day rate, this produces an annualised income of between £92,000 and £96,000, depending on the number of weeks used.
Is annualised income the same as the amount I can borrow?
No. Annualised income is the income figure a lender may use when assessing your application. The amount you can actually borrow depends on the lender’s wider affordability assessment.
Do all mortgage lenders use contractor day rates?
No. Some lenders may assess your contract and day rate, while others rely more heavily on payslips, company accounts or historic taxable income.
