How results are calculated
Gross5000
Tax25%
Net3750
The calculator builds pay from three numbers you enter: a tax rate in percent, optional social charges in percent, and a fixed other deduction. You pick a direction, enter an amount, and set a rate. On gross to net, tax and social are each a percent of gross, rounded to the cent, then subtracted with the other deduction. On net to gross, first gross = (net + other) ÷ (1 − percent sum / 100), then the same tax and social amounts.
At 5000 gross and 25% tax, net is 3750, because 1250 comes off as tax alone. At 8000, 20% tax, and 10% social charges the wedge is 30%, so 2400 comes off and 5600 remains. From 4000 net at 25% alone you divide by 0.75 and need 5333.33 gross.
Direction is a list: Gross → Net or Net → Gross. Amount is that one paycheck. Tax rate (%) is required. Social contributions (%) and Other deductions sit under extra fields. A blank field means zero, not a guessed statutory charge. Click Calculate and read net, gross, tax, and any social or other amount.
Invoice VAT is on the VAT calculator. There 1000 net at 23% is 230 tax. The income tax page uses a two-bracket yearly scale with a 120,000 threshold as its Polish-scale default; that is not a U.S. Form 1040. This calculator does not know brackets or reliefs.
This is a flat percent of gross. There are no statutory social charges and no computed income-tax advance. You enter 25%, you get 25% of gross. For an employment contract use a full payroll tool or an accountant.
Enter 5000 gross, a 25% tax rate, and Gross → Net. Check 3750 net. Then try 4000 net and the same 25% to see 5333.33 gross.
How to use
- In Direction, choose Gross → Net when you know pay before deductions, or Net → Gross when you know take-home.
- In Amount, enter that paycheck. Tax rate (%) is a flat percent, for example 25. The 10%, 12%, 22%, and 24% buttons only fill that field. They are not a W-2.
- Social contributions (%) and Other deductions are optional, under the extra fields. A blank field means zero.
- Click Calculate. At 5000 and 25%, net should be 3750. At 8000 gross, 20% tax, and 10% social charges you keep 5600.
- Read the tax, social, and other amounts in the result. Net share and the reverse check sit under them. For invoice VAT, open the sibling page.
Flat net and gross pay, not invoice VAT
The calculator uses one flat percent of the amount, optional social charges, and a fixed other deduction. 5000 gross at 25% leaves 3750. 4000 net at the same 25% needs 5333.33 gross.
- Gross
- Pay before the wedge. 5000 at 25% leaves 3750. 8000 at 20% tax and 10% social leaves 5600.
- Net
- Pay after the wedge. 4000 net at 25% inverts to 4000 / 0.75 = 5333.33 gross.
- Tax
- The Tax rate (%) field, one flat percent. At 25% of 5000, tax is 1250. Social charges add to the same percent total.

Common questions
What is a net to gross pay calculator?
The calculator converts pay between gross and take-home using a flat tax percent, optional social-charge percents, and a fixed other deduction. At 5000 gross and 25% tax, take-home is 3750. Not a full FICA/state paycheck engine and not a VAT tool.
How do I calculate take-home from gross?
3750 net. Tax is 5000 × 0.25 = 1250. Social charges are a separate field when you use them.
How do I calculate gross from net?
4000 ÷ 0.75 = 5333.33 gross. The calculator uses the same equation, with no social charges and no flat other amount.
Is this a full paycheck calculator with federal and state tax?
No. You enter flat percents. There are no IRS brackets, state tables, or employer FICA splits built in.
Is this a full income-tax and social-charge return?
No. It is a flat percent plus an optional fixed amount. There are no brackets, reliefs, or statutory tables.
Is this the same as a VAT net/gross converter?
No. This page models wages. VAT or sales-tax net/gross is a different calculator.
How do social-charge percents change take-home?
Net 5600. Combined 30% of 8000 is 2400, so 8000 − 2400 remains.
How is Direction different from Amount?
Direction is a two-way list. Amount is one paycheck. Depending on the direction, the calculator treats it as gross or net.
What if I leave social contributions blank?
A blank field means zero. The calculator does not insert a statutory table. Other deductions are also zero until you enter them.
How is this different from the VAT calculator?
VAT splits invoice tax. Here you have a wage wedge. 1000 net at 23% VAT is a different page.
Is 25% the second income-tax bracket?
No. 25 is the number you enter. This page does not apply U.S. tax brackets. The income tax page uses a simplified two-rate scale with a Polish-scale default.
How do I add a fixed other deduction?
Open the extra fields and enter 600 in Other deductions. On gross to net that amount comes off after the percents.
What currency is the result in?
The same currency as the amount. 3750 stays 3750. The header symbol only labels the number.
What do the 10%, 12%, 22%, and 24% buttons do?
They fill the tax-rate field. The calculator still uses one flat percent. They are not a W-2 and not FICA. A simplified income-tax scale is on the income tax page.
Knowledge sources
The wedge uses the percents you enter, not a payroll table and not a withholding filing.
