Self-Employed Mortgage Calculator UK
A borrowing estimate for sole traders, contractors and Ltd company directors.
Borrowing Calculator
Estimate how much you may be able to borrow before checking repayments.
This is an estimate only. Lenders use their own affordability models, income treatment, credit checks, property checks and stress tests.
Use the repayment calculator next, or request a callback if you want an adviser to discuss your circumstances.
Using this calculator does not affect your credit score. No obligation.
Calculator results are estimates only and are for general information only. They are not mortgage offers or decisions in principle.
How lenders assess self-employed income
- Sole traders — usually 2 years of SA302s plus tax year overviews; lenders often average net profit.
- Ltd company directors — most lenders use salary + dividends; some specialists use salary + retained profit.
- Contractors — day-rate × 5 × 46–48 weeks for specialist contractor lenders.
- CIS subcontractors — some lenders use gross CIS day-rate; others fall back to net profit on the SA302.
