UK Income Tax And National Insurance Calculator is a planned calculator in the tax section of Super Calculator, covering income tax.
What this calculator will compute
Inputs: gross salary (GBP), tax code, pension contribution (%), student loan plan, Scottish taxpayer flag and self employed flag.
Outputs: income tax (GBP), National Insurance (GBP), take home pay (GBP), effective rate (%) and marginal rate (%).
Formula, recorded as scope and not yet verified against a primary source: Income tax on bands above the personal allowance of 12,570 pounds, with the allowance reduced by one pound for every two pounds of income above 100,000 pounds so that it is exhausted at 125,140 pounds, producing an effective 60% marginal band. National Insurance is charged separately on earnings between the primary threshold and the upper earnings limit, then at a lower rate above.
