What this tool is used for

• Working out what a job offer actually pays into your account each month.
• Comparing two offers where one has a higher gross but different deductions.
• Checking a payslip against what the deductions should be.
• Seeing how a pension contribution change affects take-home pay.
• Estimating the effect of a raise after tax rather than before it.

Frequently Asked Questions

Why does the pre-tax deduction cut income tax but not the social contribution?

Because that is how a traditional 401(k) behaves. The pre-tax percentage is subtracted before the income-tax rate is applied, but the social rate is applied to the full gross — US FICA is levied on gross pay, and deferring into a retirement plan does not reduce it.

What is the 7.65% default?

The US employee share of FICA: 6.2% Social Security plus 1.45% Medicare. Your employer pays the same again on top. The 6.2% half stops at an annual wage base that changes every year, so above that ceiling a flat rate overstates the deduction.

Why one flat tax rate instead of brackets?

A bracket table is country- and year-specific and goes stale within months. Enter your effective rate — total tax ÷ gross from last year's return — not your marginal bracket. Using a 24% marginal rate where the effective rate is 14% understates take-home badly.

Is the effective rate shown really all tax?

No — it is total deductions ÷ gross, and that includes the pre-tax contribution, which is still your money sitting in a retirement account. For the tax-only picture, read the income tax and social lines and ignore the pre-tax row.

How are the monthly and weekly figures derived?

Annual net ÷ 12 and ÷ 52. If you are paid fortnightly you receive 26 cheques a year, not 24, so a bi-weekly amount is annual ÷ 26 — noticeably less than half the monthly figure. Semi-monthly payroll is the one that divides by 24.

Common errors and gotchas

• Using a generic rate rather than your own jurisdiction's bands, which is where the answer actually comes from.
• Omitting employer-side contributions, which are a cost to them and not a deduction from you.
• Forgetting salary sacrifice reduces taxable pay, so the deduction is smaller than the contribution.
• Comparing an annual figure against a monthly one, which is the most common arithmetic slip here.
• Treating the result as authoritative when only a payroll run and a tax return settle it.
