Payslip Calculator

What does this tool calculate?

It takes a gross monthly salary, multiplies by 12 to get an annual figure, applies a set of tax brackets and contribution rates that are built into the tool for the country you pick, and divides back to monthly lines. The result is an estimate with one line per deduction and a net monthly pay. It is not payroll software, and every threshold is a fixed value inside the tool.

Why will my real payslip differ?

The figures are simplified and fixed. Employer-specific allowances, tax codes, state, provincial or local taxes, student loans, benefits, bonuses and mid-year changes are not modelled, and the built-in thresholds are not updated by tax year. Tax and contribution rules vary by country and change over time, so check your official payslip and local rules before relying on any figure here.

How is the pension percentage treated?

It is taken as a share of gross pay and shown as a deduction in every country. For the United States and the United Kingdom, this tool also subtracts it from the income used for the income tax calculation. For India, Canada and Australia it is deducted from pay but does not reduce the tax calculated, so net pay for those countries may be lower than a tax-advantaged arrangement would give. The percentage is limited to between 0 and 100.

What is built in for the United States?

The tool uses a standard deduction of $14,600 for single and $29,200 for married filing jointly, seven progressive brackets for each status, Social Security at 6.2% on pay up to a built-in ceiling equal to $160,200 a year, and Medicare at 1.45%. State income tax is not included. These are the figures built into this tool and may not match the current tax year.

What is built in for the United Kingdom?

The tool uses a personal allowance of £12,570, with a reduction of £1 for every £2 of income above £100,000 (the pension amount is taken off first), income tax at 20%, 40% and 45% with the 40% band starting after £37,700 of taxable income and the 45% band after £125,140, and employee National Insurance at 8% between £12,570 and £50,270 and 2% above. Student loans and tax codes are not included.

What does the India calculation assume?

It assumes basic pay is 50% of gross, so employee provident fund is the smaller of 12% of basic and ₹1,800 a month, adds a flat ₹200 professional tax, and taxes annual gross using slab rates from 0% up to 30% plus 4% cess. No standard deduction, rebate, HRA, LTA or exemption is applied, so the tax line may differ from a real payslip where such reliefs apply.

How are Canada and Australia handled?

Canada: federal tax brackets less a credit of 15,705 at 15%, CPP at 5.95% on pay between 3,500 and 68,500 a year and EI at 1.66% up to 63,200 a year; provincial tax is not included. Australia: income tax rates of 0%, 19%, 32.5%, 37% and 45% on built-in brackets, a flat 2% Medicare levy with no low-income threshold, and an informational employer super line at 11.5% that is not deducted from your pay. Check the current rates with your tax authority.

What happens with zero or unusual input?

A gross of zero returns zero on every line. A negative gross is treated as zero. Filing status only affects the United States. Selecting no recognised country returns the message “Please select a country.”
