Picture this: your offer letter says 100,000 a month, so you plan your rent, your bills and even a small holiday around that number — then payday comes and only 85,000 lands in your bank. Where did the other 15,000 go? If that surprise has ever stung you, you are not alone. Most of us plan our lives around the big number on the offer letter, and almost nobody tells us the real number we will actually take home.
The good news is that the real number takes 30 seconds to find out — once you know the simple maths behind it. This article shows you exactly how your salary shrinks from gross to net, works through a real example with you, and gives you a free tool that does the whole calculation in one click. No spreadsheets, no tax tables, no guesswork.
Key Takeaways
- Your gross salary is the big number before deductions; your net pay — your take-home pay — is what actually reaches your bank.
- Net pay = gross salary − income tax − other monthly deductions. That is the whole formula.
- A salary of 100,000 with 10% tax and 5,000 of other deductions leaves a net monthly pay of 85,000.
- Always budget from your net pay, never from your gross salary, or your budget will be wrong every month.
- The free Salary Calculator on MultiTool Hub works out your take-home pay in seconds — no signup, no cost.
Try the free Salary Calculator — type your gross salary, tax rate and deductions, and see your real take-home pay instantly. No signup, takes 30 seconds.
What is a salary calculator?
A salary calculator is a free online tool that turns your gross monthly salary into your net take-home pay. Type in your gross salary, your income tax rate and your other monthly deductions, and it instantly shows your tax amount, total deductions, net monthly pay and net yearly pay — so you can budget with the money you really receive.
Think of it like a payslip translator. Your employer speaks in gross salary — the full amount before anything is taken off. Your bank speaks in net pay — the amount that actually arrives. A salary calculator translates between the two in seconds, and it never gets the maths wrong.
How does a salary calculator work?
A salary calculator uses three simple steps, and you can check every one of them by hand.
- Step 1 — Work out the tax: tax amount = gross salary × tax rate ÷ 100. On a salary of 100,000 with 10% tax, that is 10,000.
- Step 2 — Add up all deductions: total deductions = tax amount + other monthly deductions. With 5,000 of other deductions, that is 15,000.
- Step 3 — Subtract from the gross: net monthly pay = gross salary − total deductions. Here that is 100,000 − 15,000 = 85,000.
Multiply the net monthly pay by 12 and you have your net yearly pay: 85,000 × 12 = 1,020,000. That is the whole method — no hidden steps, no tax tables to look up. The key point: net pay is simply gross pay minus everything taken off, and every deduction matters.
Why is your payslip number not your real salary?
Three things shrink your salary before it reaches you, and each one is normal — the surprise only comes when you do not expect them.
Income tax is the biggest one. Your employer deducts it from your pay before you ever see it, at whatever rate applies to your income. A higher salary often means a higher tax rate, so a pay rise does not always add as much to your bank as it adds to your offer letter.
Provident fund and pension come next. Many employers put a fixed part of your salary into a savings fund for your future. It is your money, and it grows for you — but you cannot spend it this month.
Other deductions are the small ones people forget: health insurance, a staff loan repayment, a union fee. Each one is small on its own, but together they can take thousands off your pay every month.
Here is the trap: if you budget from the gross number, you will plan to spend money that never arrives. Rent, bills, groceries and savings all come from the net number. That is why the first rule of salary planning is simple — budget from your net pay, the money that actually lands in your bank.
Worked example: a salary of 100,000 — what do you really take home?
Let us do one full example together, step by step, exactly as the tool does it. Imagine you are offered a job at 100,000 a month, with 10% income tax and 5,000 a month going to provident fund and insurance.
- Gross monthly salary: 100,000.
- Income tax: 100,000 × 10 ÷ 100 = 10,000.
- Other deductions: 5,000.
- Total deductions: 10,000 + 5,000 = 15,000.
- Net monthly pay: 100,000 − 15,000 = 85,000.
- Net yearly pay: 85,000 × 12 = 1,020,000.
Now try it yourself in the tool — type 100000, 10 and 5000 into the three boxes and click Calculate Salary. You will see the same numbers in a neat breakdown table: tax 10,000.00, total deductions 15,000.00, net monthly pay 85,000.00, net yearly pay 1,020,000.00. Then change the tax rate to 15% and watch your take-home pay drop to 80,000. That is the power of seeing the real number before you sign anything.

Using the tool takes less than a minute, and there is nothing to install or sign up for.

- Type your gross monthly salary — the full amount before tax or deductions.
- Type your income tax rate as a percentage. Type 0 if no tax is deducted from your pay.
- Type any other monthly deductions — provident fund, insurance or anything else, added together. Type 0 if there are none.
- Click Calculate Salary. Your breakdown appears instantly: tax amount, total deductions, net monthly pay, net yearly pay and gross yearly salary.
- Click Copy Results to copy the whole breakdown, or Clear to start again.
If you leave a box empty or type a tax rate above 100, the tool tells you plainly what to fix — it never hangs and never shows a blank screen.
Who uses a salary calculator?
Job seekers use it to compare two offers fairly. An offer of 120,000 with heavy deductions can leave less in hand than an offer of 110,000 with light ones — the calculator shows the truth in seconds.
Employees use it to check a payslip. If the number in your bank does not match the calculator, you know exactly which line to ask your employer about.
Freelancers use it in reverse: they work out how much of each payment to set aside for tax, so there is no nasty surprise at the end of the year. If you also send quotes to clients, the Quotation Generator on MultiTool Hub builds the quote for you.
Teachers and students use it to understand a first salary or a new pay scale. A first job feels very different when you know the real monthly figure before you start spending — and if you want to see that money grow over time, the Compound Interest Calculator shows what your savings become year by year.
Anyone planning a budget uses it as step one. Rent, groceries, savings and fun money all come from net pay — work out the real number first, then split it. The Percentage Calculator helps you split that budget into percentages, and the Tip Calculator splits a restaurant bill fairly when you eat out.
5 mistakes to avoid when you budget from your salary
1. Budgeting from the gross number. This is the most common mistake, and the most expensive. Your budget must start from net pay — the money that actually arrives.
2. Forgetting the small deductions. Insurance, union fees and loan repayments look tiny alone, but together they can take thousands a month. Add them all into the "other deductions" box.
3. Comparing offers by gross salary only. Two jobs with the same gross pay can leave very different amounts in hand. Always compare the net figures side by side.
4. Ignoring the yearly figure. A monthly number feels small, but the yearly net pay tells you what you really earn — and it is the number banks and landlords ask about.
5. Never re-checking after a change. A pay rise, a new tax rate or a finished loan changes your take-home pay. Re-run the calculator whenever anything changes — it takes 30 seconds.

Salary Calculator FAQ
What is the difference between gross salary and net salary? Gross salary is your full pay before anything is taken off; net salary is what is left after tax and other deductions and is the money that reaches your bank. Your offer letter shows gross, your bank statement shows net, and the gap between them is tax plus deductions.
Is this salary calculator accurate? It is accurate for the numbers you type in — the maths is exact. But it is an estimate of your real pay, because actual tax depends on your country's tax slabs, allowances and your employer's payroll. Always check the final figure against your payslip.
What should I type if I do not pay income tax? Type 0 in the tax rate box. The calculator will then treat your tax as zero and only subtract your other deductions. The same goes for other deductions — type 0 if there are none.
Can I use it to compare two job offers? Yes — that is one of its best uses. Run each offer through the calculator with its own tax rate and deductions, then compare the net monthly pay figures. The higher gross salary is not always the better offer.
