What is a net to gross salary calculator?
A net to gross calculator works in reverse. Instead of starting with a gross salary and calculating what you take home, you start with your desired take home pay and calculate what gross salary you need to earn. This is useful when negotiating a job offer, comparing salaries across different roles, or working out what you need to ask for to meet a financial goal.
This calculator uses a binary search algorithm, running hundreds of calculations to find the exact gross salary that produces your target net pay. The confirmed net figure shows you that the result is accurate to within a few pence.
How to use this in a salary negotiation
If you know you need £2,500 per month to cover your expenses, enter £30,000 in the annual field (or £2,500 in the monthly field). The calculator will tell you that you need a gross salary of around £38,500 to achieve that. You now have a specific number to present in any salary discussion.
Remember to include pension contributions in your calculation if you will be enrolled in a workplace pension. A standard 5% employee contribution on a £38,500 salary would reduce your take home by around £1,200 per year, so factor this in when setting your target.
