Use this page as a planning tool, not as a substitute for official payroll, HMRC, lender, or contractual calculations. The output depends on complete and accurate inputs, including working pattern, deduction type, and tax-year context. If your scenario includes irregular pay, unpaid leave, overtime premiums, salary sacrifice, or multiple income sources, test at least two scenarios before deciding. That comparison usually reveals whether a small assumption is driving a large change in the final result.
For UK-focused decisions, cross-check key thresholds and rates against current GOV.UK guidance and your own documents. Keep your assumptions consistent across monthly and annual views, and verify whether figures should be gross or net before entering them. Where relevant, include pension contributions, student loan plan, and any benefits-in-kind so the result reflects real take-home impact.
After calculating, use the result for action: compare alternatives, estimate affordability, and identify your break-even point. If the output influences legal, tax, lending, or employment choices, confirm with official statements or a qualified adviser.
Uplift is the difference between an original value and a new, higher value, expressed as a percentage. The formula is: Uplift % = ((New Value − Original Value) ÷ Original Value) × 100. For example, if a property was valued at £300,000 and is now worth £360,000, the uplift is ((360,000 − 300,000) ÷ 300,000) × 100 = 20%.
| Scenario | Original | New Value | Uplift % |
|---|---|---|---|
| Salary increase | £30,000 | £32,000 | +6.7% |
| House value gain | £250,000 | £280,000 | +12.0% |
| Investment return | £5,000 | £5,350 | +7.0% |
| Price decrease | £120 | £96 | −20.0% |
| Council tax rise | £1,800 | £1,890 | +5.0% |
| Energy bill change | £1,568 | £1,849 | +17.9% |
In UK property and planning, uplift refers to the increase in land or property value resulting from a planning permission, infrastructure improvement, or change in use. For example, agricultural land granted planning permission for housing can rise from £10,000/acre to £1 million+/acre — an uplift of 9,900%. Councils increasingly use clawback clauses and Community Infrastructure Levies (CIL) to capture a share of planning uplift for public benefit.
Uplift and percentage increase measure the same thing mathematically: the relative change between an old and new value. Uplift is typically used in property, finance, and business contexts to describe positive value growth. Percentage increase is the more general mathematical term used in education and everyday calculations. A downward change is called a percentage decrease or a negative uplift.
To find the original value before an uplift, divide the new value by (1 + uplift%/100). For example, if a salary rose by 8% to reach £32,400, the original salary was £32,400 ÷ 1.08 = £30,000. This reverse calculation is essential for VAT-inclusive price calculations (divide by 1.2 to remove 20% VAT), RPI adjustments, and checking whether a quoted uplift percentage is accurate.
UK salary uplifts (pay rises) averaged approximately 5.9% in 2023 and are forecast around 3-4% for 2025/26 as wage growth moderates alongside lower inflation. The National Minimum Wage uplift for 2025/26 is 6.7% (£11.44 to £12.21 per hour for workers aged 21+). Public sector pay awards have ranged from 5% to 9.4% in recent years. The UK salary calculator can show you the take-home pay impact of any pay rise.
