About the Salary Calculator

Salary calculators convert between annual, monthly, weekly, daily, and hourly pay rates while calculating Income Tax and National Insurance deductions. Understanding your take-home pay matters when evaluating job offers, comparing contract types, or estimating the true cost of a new hire including employer NI contributions.

UK Income Tax bands 2024/25

Gross vs net vs cost to employer

Gross salary is the agreed annual amount before deductions. Net (take-home) pay is what you receive after Income Tax and Employee NI. Cost to employer is gross salary plus Employer NI (13.8% above the secondary threshold) — typically 10-15% higher than the gross salary and the true cost of hiring someone.

Salary negotiation and total compensation

When evaluating a job offer, look beyond the headline salary. Employer pension contributions (a 5% employer match on a £40,000 salary adds £2,000/year), private health insurance (worth £500-1,500/year), life assurance, income protection, and other benefits form the total compensation package. Salary sacrifice schemes can also significantly affect take-home pay.

Frequently Asked Questions

How do I convert an annual salary to an hourly rate?
Divide the annual salary by working hours per year. Standard UK full-time: 52 weeks x 37.5 hours = 1,950 hours/year. So 30,000 / 1,950 = 15.38 per hour. For 40-hour weeks: 30,000 / 2,080 = 14.42 per hour.
What is the difference between gross and net salary?
Gross salary is your total pay before deductions. Net (take-home) pay is what reaches your bank account after Income Tax, Employee National Insurance, and pension contributions. For a 35,000 UK salary, net pay is approximately 27,500 depending on pension and other deductions.
How much National Insurance do I pay?
For 2024/25, Employee NI is 8% on earnings between 12,570 and 50,270, and 2% on earnings above 50,270. There is no NI on earnings below 12,570. Employer NI is 13.8% on earnings above the secondary threshold (9,100).
Does a salary increase always increase take-home pay?
Yes, always. Higher marginal tax rates apply only to the portion of income in the new band — your previous income stays at its current rate. Even if a pay rise pushes you into the 40% band, only the income above 50,270 is taxed at 40%. Your total take-home always increases.
How do I calculate UK income tax manually?
Subtract the personal allowance (12,570) from gross salary. Tax the first 37,700 of the remainder at 20%. Tax any amount between 37,700 and 112,570 at 40%. Tax anything above at 45%. Add Employee NI: 8% on earnings 12,570-50,270, 2% above that.
