Take-Home Pay, Explained
After reading this you can turn any gross salary into an estimated net figure, see exactly which slice each deduction takes, and know when a flat-rate model is close enough to trust.
Your gross pay is the number in the job offer. Your take-home pay is the number that reaches your bank account. The gap between them is deductions: income tax, social contributions, and sometimes extras like a union fee or a private pension. This tool models that gap with flat percentages you set yourself.
Here is the hook. A gross salary of 5000 per month, taxed at 15% with 18.5% social contributions, leaves you 3325. That is a third of the headline number gone before you spend a cent. The rest of this article shows where each part of that 1675 goes and how to reproduce it.
What the calculator does
It applies deduction rates to your gross pay and reports what remains. Every deduction is a percentage of gross, not of some running balance. That single rule keeps the math transparent and the arithmetic easy to check by hand.
- Gross pay
- Your total pay before any deduction. This is usually the number quoted in a contract or an offer.
- Deduction rate
- A percentage of gross removed for a specific purpose, for example
15%income tax. - Net pay (take-home)
- What remains after all deductions. This is the money you actually receive.
The defaults match Hungary's flat system: 15% personal income tax plus 18.5% employee social contributions. You can change every rate, so the same tool works for any place with roughly flat deductions, or as a rough estimate anywhere.
When to use it, and when not to
Use it when your deductions really are flat, or close to flat. A single combined rate that does not change as you earn more is exactly what this model assumes. Hungary fits. So does a quick estimate where you already know your effective rate and just want the resulting net figure.
Do not trust this model for a progressive tax system without adjusting the rate. In countries with brackets (the United States, Germany, the United Kingdom, and many others), your marginal rate rises as income rises, so no single percentage describes the whole salary. You can still use the tool if you enter your effective rate, meaning total tax divided by gross, but that number is something you must compute separately.
The model also ignores fixed allowances, tax-free thresholds, and credits that reduce tax by a flat amount rather than a percentage. If your country gives everyone the first 1000 tax-free, a pure percentage will overstate the tax you owe.
The formula and the intuition
Add the three rates, treat the sum as one total deduction rate, and take the rest of your gross.
Here r_{\text{tax}} is the income tax rate in percent, r_{\text{social}} is the social contribution rate, and r_{\text{other}} is any extra deduction. The term in parentheses is your retention rate: the fraction of gross you keep.
The intuition is that percentages of the same base simply add. Because every rate is charged on gross, not on the balance left after the previous cut, the order does not matter and you never compound one deduction on top of another. If the combined rate is 33.5%, you keep 66.5%, full stop.
Some real systems do stack deductions, taking one from the amount left after another. If yours does, this flat-sum model will be slightly off. For rates this size the difference is small but not zero, and the worked example below shows how to spot it.
A worked example with the demo numbers
Gross 5000 per month, Hungarian rates
These are the tool's default values, so you can press Calculate and match every figure.
- Add the rates:
15 + 18.5 + 0 = 33.5%. - Convert to a retention rate:
1 - 0.335 = 0.665. - Multiply by gross:
5000 × 0.665 = 3325. - Break the
1675of deductions apart: income tax is5000 × 0.15 = 750, social is5000 × 0.185 = 925, and750 + 925 = 1675.
Your monthly take-home is 3325. Over a year that is 39,900 net against 60,000 gross, with 20,100 going to deductions.
Watch the retention rate move
The single most useful thing to feel is how the combined deduction rate bends your net pay. A few points added to social contributions costs you real money every month. The widget below lets you push the rates and watch net pay respond in a straight line.
Reading and interpreting the result
The net figure is the headline, but two derived numbers tell you more. The first is the retention rate itself: 3325 / 5000 = 0.665, or 66.5%. Compare that across job offers to see which one actually pays more after deductions, since a higher gross with a higher rate can lose to a lower gross with a lower rate.
The second is the annual gap. Switching the period to year multiplies everything by twelve if you entered a monthly figure, so the same 33.5% costs you 20,100 per year here. Seeing deductions as an annual sum makes small rate differences feel as large as they really are.
| Combined rate | Retention | Net pay | Deductions |
|---|---|---|---|
| 20% | 0.80 | 4000 | 1000 |
| 33.5% | 0.665 | 3325 | 1675 |
| 40% | 0.60 | 3000 | 2000 |
| 50% | 0.50 | 2500 | 2500 |
Common mistakes
The errors below are the ones that make an estimate wrong by hundreds per month.
- Using a marginal rate as if it were flat. In a bracket system your top bracket rate is higher than your effective rate. Feeding the top rate into a flat model overstates tax. Use total tax divided by gross instead.
- Forgetting employer versus employee contributions. Social contributions often have an employer side you never see and an employee side deducted from your pay. Only the employee side belongs in this calculator.
- Mixing periods. Enter a monthly gross with the period set to year and every result is off by a factor of twelve. Match the period to the number you typed.
- Ignoring flat allowances. A tax-free threshold or a fixed credit changes your real effective rate, and a pure percentage cannot capture it.

Frequently asked questions
Why is my real payslip different from this estimate?
Real payslips include allowances, credits, capped contributions, and sometimes benefits taxed separately. A flat model captures none of that. Treat the result as an estimate and reconcile it against one real payslip to find your true effective rate.
Should I enter the employer's share of social contributions?
No. Only enter what is deducted from your gross. The employer's contribution is a cost to the company, not a cut from your pay, so including it would understate your take-home.
How do I use this in a progressive tax country?
Compute your effective income tax rate first: total annual tax divided by annual gross. Enter that percentage as the income tax rate. The result then approximates your net pay for that income level, though it breaks if your income changes enough to shift brackets.
Does the order of deductions matter?
Not in this model. Every rate applies to gross, so adding 15% and 18.5% gives the same net as any other order. Systems that deduct one item from the balance left after another can differ slightly, but this tool does not.
What counts as an "other" deduction?
Anything charged as a percentage of gross that is not income tax or social contributions: a union fee, a mandatory private pension slice, or a solidarity levy. If a deduction is a fixed amount rather than a percentage, this field cannot represent it exactly.
