Income Multiple Scenario
Compare a target loan with a chosen income-multiple scenario using qualifying income figures.
Reference scope documented 2026-10-25. Residential tax bands are jurisdiction-specific. Rates, fees, budget buffers and lender ratios must come from current quotes or clearly labeled assumptions. Confirm legal buyer status and scheme conditions.

How this estimate works
Income × your selected multiple gives a scenario loan. Target required multiple = max(0, price − deposit) / entered qualifying income.
Assumptions and limits
- Amounts are GBP. Enter actual quotes, balances and costs. Planning settings are editable assumptions; no lender rate is fabricated.
- Monthly nominal-rate amortization; fixed-rate projection across the entered remaining repayment period. Actual daily accrual, payment dates, product fees, rate resets and lender rounding can differ.
- This is educational scenario arithmetic, not a mortgage offer, agreement in principle, tax assessment or scheme/credit approval.
- A 4.5× high-LTI threshold is a lending-flow policy concept; it does not give every borrower an entitlement or a universal individual ceiling. The October 2026 policy publication includes forward-effective provisions; this tool makes no personal regulatory eligibility determination.

This is a hypothetical arithmetic example in GBP, not a current lender quote, market observation or borrower record. The same calculator model produces the figures below. Its input assumptions are shown so that you can reproduce or change the scenario.
| Assumed input | Illustration value |
|---|---|
| Confirmed annual qualifying household income (GBP) | 60,000 |
| Other accepted income not already included (GBP) | 0 |
| Lender / planning income multiple | 4.5 |
| Property price / applicable value (GBP) | 350,000 |
| Cash deposit available after closing reserves (GBP) | 87,500 |
| Calculated measure | Result |
|---|---|
| Entered annual qualifying income | £60,000.00 |
| Loan at your selected income multiple | £270,000.00 |
| Price at that multiple plus deposit | £357,500.00 |
| Required loan for target price | £262,500.00 |
| Required income multiple | 4.375 |
| Loan gap against selected multiple | £0.00 |
Amounts use unrounded intermediate arithmetic and are rounded only for display. Selecting different costs, rates, payment dates or terms changes the result; no illustration value is prefilled into your personal financial fields.
