UK Net to Gross Salary Calculator 2025/26
Required Salary Calculator

How do I calculate gross salary from a target net salary?

When you enter a target take-home salary, this calculator works backwards through the UK PAYE system to estimate the gross salary you'd need to earn before deductions. Rather than calculating what you'll take home from a given gross — the direction most salary calculators work — this tool solves the reverse problem: what gross salary do I need to achieve a specific net income?

Under PAYE (Pay As You Earn), several deductions are taken from your salary before it reaches your bank account:

• Income Tax — deducted in bands (20%, 40%, 45%) above the personal allowance
• National Insurance contributions (NICs) — employee NICs deducted at source
• Workplace pension contributions — either via salary sacrifice or net pay arrangement
• Student loan repayments — Plan 1, 2, 4, 5 or Postgraduate, each with different thresholds

Because these deductions are threshold-based and non-linear, the maths is more complex than simply dividing by a fixed percentage. A £1,000 increase in gross salary near the 40% tax band threshold, for example, results in a significantly smaller increase in net pay than the same increase at a lower gross. This calculator handles all of that complexity automatically for the selected tax year.

How to Use This Calculator

Using the net to gross calculator is straightforward:

1. Enter your desired take-home pay — type the net amount you want to receive. This is the money that lands in your bank account after all deductions.
2. Select the time period — choose whether your target figure is annual, monthly, weekly, fortnightly, four-weekly, or daily. The calculator converts everything to an annual gross and then back to your chosen period.
3. Add pension contributions (optional) — if you contribute to a workplace pension, enter either a percentage of your salary or a fixed monetary amount. You'll also need to select whether your pension is set up as salary sacrifice (pre-tax) or a net pay arrangement (post-tax relief at source), as this affects the gross salary required.
4. Select student loan plans (optional) — tick any student loan plans that apply to you. UK student loan repayments are income-contingent and differ significantly depending on when and where you studied: Plan 1, Plan 2, Plan 4 (Scotland), Plan 5 (post-2023 entrants), and Postgraduate loans each have different repayment thresholds and rates.
5. View the results — the calculator will display the estimated gross salary required, alongside a full breakdown of each deduction: income tax by band, National Insurance, pension, and student loan repayments.

Why Net to Gross Is Useful

The standard approach to salary calculation is gross to net: you know what you earn, and you want to know what you'll take home. But there are many situations where you need to work in reverse:

• Salary negotiations — if you know you need £3,000 per month to cover your outgoings, you can find out exactly what gross salary to negotiate for, rather than guessing.
• Budgeting and financial planning — work out what gross income you need to afford rent, a mortgage, or savings targets.
• Comparing job offers — two employers offering different gross salaries with different pension arrangements can be compared on the basis of actual take-home pay.
• Freelancers moving to employment — if you're used to receiving a day rate or project fee and are considering a salaried role, this tool helps you understand what gross salary you'd need to replicate your current net income.
• Payroll and HR teams — quickly determine what gross salary package achieves a specific net-of-deductions figure for a new hire or pay review.
