A banker bonus mortgage is a UK home loan assessed using a banker’s variable bonus—typically averaged over two years—with only part counted (often 50–60%) and, if paid in foreign currency such as USD, discounted by 20–25% for exchange-rate risk. Evidence of consistency is usually required.
Client Profile
Persona: Investment banking associate (London)
Income: £120k base + £80k–£140k annual bonus (paid in USD)
Target Property: £1.25m flat
Loan Required: 75% LTV (£937,500)
The Challenge
Foreign currency volatility: Lenders apply discounts to non-GBP income to manage exchange rate risk. For USD, typical haircuts we see are around 20–25% depending on lender.
Discretionary bonus: Many lenders cap how much bonus counts—often 50% of a two-year average for discretionary awards; some model around 60% where policy allows.
Higher borrowing need: Hitting the required £937,500 at 75% LTV meant stretching affordability. Some mainstream lenders do offer up to 5.5× income if thresholds and LTV caps are met.
Our Approach
Two-Year Bonus Average: We used a 24-month track record of cash bonuses to demonstrate sustainability, aligning with lenders that consider a two-year average and restrict discretionary elements.
Foreign Currency Haircut: We modelled affordability both at a 20% and 25% haircut on the USD bonus to match differing lender policies and mitigate exchange-rate swings.
Evidence Pack: Provided bonus award letters, payslips showing the USD bonus credit, and bank statements; cross-checked YTD figures to support consistency and recency.
Lender Selection: We targeted a high-street lender with appetite for complex remuneration and scope for stretched LTI where incomes meet set thresholds and LTV ≤85%.
Stress-Testing: We ran sensitivity checks for lower bonus years and weaker USD/GBP rates to ensure affordability still cleared lender buffers.

The Outcome
Offer Achieved: £937,500 at 75% LTV on the £1.25m purchase.
Affordability Stretch: Equivalent to ~5.2× the lender-assessed income after applying the USD haircut and bonus scaling.
Future-Proofing: The structure leaves headroom against bonus variability and exchange rate shifts.
What Helped This Case Succeed
Clear Bonus Narrative: Two-year history with consistent awards and timing aligned to recent payslips.
Pragmatic Currency Treatment: Presenting parallel affordability cases at 20% and 25% haircut made it easy for underwriting to sign off.
Right Lender, Right Policy: Matching the profile to a lender comfortable with discretionary bonuses (often at 50% of a two-year average) and professional-style LTIs.
Guidance For Bankers With Bonus Income
Document the track record: Keep two years of bonus evidence and ensure YTD aligns with payslips.
Expect a currency haircut if any part of your income is paid in USD/EUR/CHF/AED. Build a buffer.
Know the rules of thumb: Many lenders use 50% of a two-year average for discretionary bonuses; some model ~60% depending on policy.
Target the right LTI framework: Certain lenders can stretch to 5–5.5× where income and LTV criteria are met.
