How this calculation works
This tool uses tax year; gross pay; pay frequency; tax code/basic assumptions; pension; student loan if supported. It returns income tax; NI; deductions; take-home. Headline results, charts, schedules, comparisons and exports are generated from the same normalized calculation state.
Worked example
Estimated take-home per pay period: 45,357.4 • Income Tax: 11,432 • Employee National Insurance: 3,210.6
Assumptions
Unless the tool says otherwise, rates are annual percentages, currency inputs are denominations rather than automatic FX conversions, and projections are mathematical models rather than guarantees. Typed values remain authoritative even outside normal slider ranges.
Limitations
Rules, limits, fees and tax calculations require a current versioned source package. When a source is stale or unavailable, the tool uses a truthful unavailable/manual state instead of pretending old data is current.
