💡 Understanding Marginal vs. Effective Tax Rates
Your marginal tax rate is the tax paid on your next pound or dollar of earnings, while your effective tax rate is the actual average percentage paid across your entire salary after tax-free personal allowances. For example, a UK salary of £45,000 falls in the 20% basic bracket, but because the first £12,570 is completely tax-free, the effective income tax rate is only 14.4%.
About this tool
How to use it
- Select your tax country (UK PAYE, US Federal, Canada, or Australia).
- Enter your gross annual salary and voluntary workplace pension contribution percentage.

Why it matters
Job offers and salary negotiations quote gross figures, which often create false expectations about actual disposable income. Deductions such as progressive tax brackets, national insurance, FICA, and pension contributions take a significant portion of earnings, making an accurate net calculator essential for budgeting.
When to use it
Use this calculator when evaluating a new job offer, planning for an annual promotion pay rise, adjusting salary sacrifice pension contributions, or creating a monthly household living budget.
Good to know
Calculations use latest progressive tax bracket structures: UK PAYE 2024/2026, US Federal standard deduction & brackets, Canada Federal brackets, and Australia ATO tax-free threshold with Medicare 2% levy.
Common questions
What is the difference between marginal and effective tax rates?
Your marginal rate is the tax rate applied to your highest slice of earnings (e.g. 40% higher rate). Your effective tax rate is the total tax paid divided by your entire gross income (often 15% to 25%), reflecting tax-free personal allowances and lower introductory brackets.
How does contributing to a pension increase take-home efficiency?
Pre-tax workplace pension contributions (salary sacrifice) reduce your taxable gross income, effectively saving you tax at your highest marginal rate while boosting your long-term retirement wealth.
Does this tool account for US state income taxes?
This tool calculates US Federal income taxes and mandatory FICA (Social Security & Medicare). State income taxes vary widely by location (ranging from 0% in Texas/Florida to over 10% in California) and should be deducted based on your local state rules.
