Reverse Tax Calculator – Work Out Gross from Net Pay in the UK
Understanding your salary, especially what you take home after tax, is essential. But what if you already know your net salary and want to calculate your gross income? That’s where our reverse tax calculator comes in handy. It helps UK employees, freelancers, and business owners accurately estimate the gross pay required to reach a specific net income.
Whether you’re negotiating a salary offer, preparing invoices, or budgeting for the year ahead, knowing how much you need to earn before tax is crucial. This page walks you through everything you need to know about using a reverse tax calculator, including how it works, who it’s for, and how it compares to traditional salary tools.
What Is a Reverse Tax Calculator?
A reverse tax calculator is a smart financial tool designed to calculate gross income based on your net salary. Instead of starting with your salary before tax and deductions (as most salary calculators do), it works the other way around.
In simple terms, if you know how much money you want to receive in your bank account after tax and deductions, the calculator tells you how much gross salary you need to earn. It factors in Income Tax, National Insurance contributions, and even thresholds such as the personal allowance.
Example:
If your target take-home pay is £2,500 per month, our reverse tax calculator will determine what gross monthly or yearly salary you need to achieve that amount, taking current tax bands and rates into account.
Who Should Use This Reverse Tax Calculator?
The reverse tax calculator is an invaluable tool for many individuals and professionals across the UK. Here’s who will benefit most:
1. Employees Negotiating Salary Offers
If you’re changing jobs and have a net income goal in mind, the reverse salary calculator helps you know what gross salary to ask for.
2. Self-employed Freelancers and Contractors
Freelancers often set their rates based on desired take-home pay. This calculator ensures your invoices are high enough to meet your post-tax income needs.
3. Small Business Owners
Planning staff salaries or drawing director’s pay? Use the reverse tax calculator income tool to plan finances accurately.
4. Accountants and Financial Advisors
Professionals helping clients make tax-efficient decisions will find this tool reliable and user-friendly.

Pension contributions (optional)

Why Knowing Your Gross Income Matters
While many people focus on their take-home salary, knowing your gross income is just as important.
1. Helps with Salary Negotiation
When applying for a new role, employers usually offer salary in gross terms. With a reverse tax calculator, you can quickly check whether the offer meets your expectations.
2. Budgeting and Financial Planning
If you’re planning expenses like mortgage payments or saving targets, knowing your gross helps you build better financial plans.
3. Tax Planning and Allowances
Understanding your gross income is crucial when looking into personal allowances, tax reliefs, and benefits thresholds.
Net to Gross – The Maths Behind the Tool
Our reverse tax calculator uses a simple but effective algorithm to reverse-engineer the deductions applied to a gross salary.
Here’s how the process works:
Adds Back Income Tax – Based on the current tax brackets (e.g., 20%, 40%, 45%), it adds back the income tax you would have paid.
Adds Back National Insurance – Accounts for Class 1 National Insurance contributions.
Adjusts for Student Loans/Pensions – Optional fields help tailor your gross salary for accuracy.
The outcome? You get a precise gross income figure that reflects your take-home salary target.

| Purpose | Estimate salary offer | Estimate take-home pay |
Both tools serve different but equally important functions. However, if your goal is to reach a specific post-tax income, the reverse salary calculator is the right choice.
