UK Net to Gross Salary Calculator

A net to gross salary calculator works in reverse to a standard take-home pay calculator. Instead of entering your gross salary to find your net pay, you enter the net (take-home) pay you want and the calculator works out what gross salary you need to achieve it, accounting for income tax, National Insurance and other deductions.

The most common reason is salary negotiation. If you want to take home £3,000 per month, you need to know what gross salary to ask for. It is also useful for comparing job offers where one salary is quoted as net and another as gross, or when budgeting for a specific monthly income target.

The calculator uses an iterative method — it starts with an estimated gross salary and repeatedly adjusts it until the resulting take-home pay matches your target net pay. This is necessary because the relationship between gross and net is not a simple linear formula due to tax bands and NI thresholds.

Yes. If you have a pension contribution, your take-home pay is reduced by the pension deduction. So if you want £3,000/month take-home after a 5% pension contribution, you need a higher gross salary than if you had no pension. The calculator accounts for this automatically.

To take home £2,000 per month (£24,000 per year) in 2025/26, you would need a gross salary of approximately £27,500 per year. The exact figure depends on your personal allowance, tax code, and any other deductions.

To take home £3,000 per month (£36,000 per year) in 2025/26, you would need a gross salary of approximately £44,000 per year. This takes into account the basic rate income tax band and standard National Insurance rates.
