Monthly take-home pay by salary
Gross monthly pay is your annual salary divided by 12. Take-home is what remains after tax and NI.

Why your first payslip can look different. Tax is worked out cumulatively across the tax year (6 April to 5 April) using your tax code, so a new starter or a code change can move a single month's tax up or down. Over a full year the total matches this calculator.
What would a pay change do to your take-home?
Compare your salary above with a raise, promotion or job offer. Higher-rate tax, National Insurance and student loan all change how much you keep.
Moving from £42,000 to £52,000 changes your take-home by +£6,958 a year (+£580 a month). You keep 70% of the extra gross pay; the rest goes in Income Tax and National Insurance. Your next pound at the new salary is taxed at a combined 42%.

Frequently asked questions
How do I calculate monthly salary after tax?
Multiply your monthly pay by 12 to get the annual figure, work out Income Tax and National Insurance on that, subtract them, and divide by 12. The calculator does this instantly. For example £3,500 a month (£42,000 a year) leaves £2,813 a month.
Is monthly pay the same every month?
For a steady salary, roughly yes. Tax is calculated cumulatively, so one-off bonuses, tax code changes and part-year employment can change individual months.
What is the monthly tax-free amount?
Your £12,570 Personal Allowance is spread evenly as £1,048 a month, and National Insurance starts above £1,048 a month.
Does this work for 4-weekly pay?
Not exactly. Four-weekly pay gives 13 pay days a year, not 12. Use the weekly calculator for a closer figure.
