Every job offer quotes a gross salary — the big number before anything is taken out. What actually lands in your bank account is the net salary, and the gap between the two surprises almost everyone the first time. Income tax, social contributions, and deductions quietly remove 15–35% of gross pay in most countries. The good news: the math behind it is the same everywhere in the world, and it fits in one formula.
No matter which country you live in, salary after tax follows the same logic:
Net salary = Gross salary − (Gross salary × Tax rate) − Deductions
That is the whole game. Three inputs — gross pay, your effective tax rate, and your deductions — and you get the number that actually matters. Let us walk through each one.
Gross pay is your salary before any tax or deduction. Job offers quote it in different units, so first convert everything to the same one — annual is easiest:
Watch out for the classic trap: offers sometimes quote "CTC" (cost to company) or include bonuses and allowances in the headline number. Only the fixed, guaranteed portion counts as gross for this calculation — treat variable bonuses separately.
This is where most people go wrong. Tax systems are usually progressive: different slices of your income are taxed at different rates. Being "in the 30% bracket" does not mean you pay 30% of your salary in tax — only the income inside that top slice is taxed at 30%.
What you need is your effective tax rate: total income tax divided by gross income. For a quick estimate, most middle-income earners land here:
| Country | Typical effective income-tax rate (middle income) |
|---|---|
| United States | ~12–22% federal + state varies |
| United Kingdom | ~15–25% |
| Canada | ~15–25% |
| Australia | ~15–25% |
| Pakistan / India | ~5–15% (slab-dependent) |
These are rough guides, not exact figures — and remember to add social contributions (Social Security, national insurance, EOBI, etc.), which are often a flat percentage on top. When in doubt, use last year's payslip: (gross − net) ÷ gross gives you your personal effective rate, the most accurate number you will ever get.
Deductions are the fixed amounts taken from every paycheck after tax in most systems:
Add them up as an annual figure. Note the subtlety: some deductions are pre-tax (they reduce your taxable income first, like many retirement contributions), which makes them slightly more valuable than their face amount. For a quick estimate, treating them as post-tax is fine — you will be within a few percent.
Once you have the annual net figure, divide by how often you are paid:
| Pay frequency | Paychecks per year | $38,400 net per check |
|---|---|---|
| Weekly | 52 | $738 |
| Biweekly | 26 | $1,477 |
| Semimonthly | 24 | $1,600 |
| Monthly | 12 | $3,200 |
Putting it all together for a $60,000 gross salary, a 22% effective tax rate, and $4,800/year in deductions:
That $3,500/month — not $5,000 — is the number to budget against. The free salary after tax calculator runs this instantly for any currency and breaks the result down by year, month, week, and paycheck.
The 10-second version: net = gross − (gross × your effective tax rate) − deductions. Divide by paychecks per year. Everything else is detail.

Multiply your gross salary by your effective tax rate, subtract that tax from gross, then subtract your annual deductions. The result is your net (after-tax) salary. Divide by 12 for monthly or by your number of paychecks per year for per-paycheck figures.
Gross salary is your pay before any tax or deductions — the number on the job offer. Net salary (take-home pay) is what remains after income tax, social contributions, and deductions are removed. Net is typically 65–85% of gross, depending on your country and tax bracket.
Your marginal rate is the tax on your last dollar earned (your top bracket). Your effective rate is total tax divided by total income — always lower than the marginal rate under progressive systems. Use the effective rate when estimating take-home pay.
First compute annual net: gross minus (gross times effective tax rate) minus annual deductions. Then divide by 12. Example: $60,000 gross at 22% tax with $4,800 deductions gives $42,000 net per year, or $3,500 per month.
Same gross pay can produce different net pay because of different deductions (retirement contributions, insurance), different tax situations (filing status, dependents, additional income), and pre-tax vs post-tax benefit choices. Gross equality never guarantees net equality.
