These are estimates based on your inputs.
How this calculator works
We reverse the take-home calculation by estimating deductions at different gross salaries. A search routine finds the gross salary that produces your target net pay.
This model uses simplified UK tax and NI thresholds and is intended for planning, not payroll accuracy.
What this calculator does
This net to gross salary calculator estimates the gross annual salary needed to reach a target take-home pay. It includes income tax, National Insurance, pension contributions, and optional student loan deductions.
Use it to translate a monthly net target into an annual gross salary for budgeting or job comparisons.
How the formula works
We convert your target net pay into an annual amount, then estimate income tax, National Insurance, pension contributions, and student loan repayments across different gross salaries. A binary search finds the salary where net pay matches your target.
This is the reverse of the Take-home salary calculator, using the same simplified tax assumptions.
Worked example
Example: you want £2,500 per month take-home with no pension contribution. The calculator estimates the gross salary required after tax and NI, then shows a breakdown of deductions.
If you add a 5% pension contribution, the required gross salary increases because more is deducted before you receive your net pay.
Common mistakes
- Using weekly or monthly targets without selecting the right frequency.
- Ignoring pension or student loan deductions.
- Assuming tax bands and thresholds are identical across the UK.
- Expecting the estimate to match a payslip exactly.
When to use this calculator
Use this when you know the take-home pay you want and need to estimate the gross salary required. If you know the gross salary and want net pay, use the Take-home salary calculator.
FAQs
Does this include employer pension contributions?
No. It only includes employee contributions, which reduce take-home pay.
Can I use this for Scotland or Wales?
This version uses England tax bands as a simplified estimate, so results may differ for other regions.
What about salary sacrifice?
Salary sacrifice can reduce tax and NI further. This calculator treats pension as a simple percentage deduction, so it is a rough estimate.
