This is a lightweight two-way income converter, not a full paycheck breakdown. Instead of modeling FICA, tax brackets, and pay frequencies, it uses a single combined deduction rate that you supply, plus an optional flat fixed deduction. Flip the toggle to go either direction: start from a gross figure to see what lands as net, or start from a net target and find the gross you would need. It is deliberately simple, so you control the rate rather than the tool guessing it.
Formula
net = gross × (1 − rate/100) − fixed; gross = (net + fixed) / (1 − rate/100)
- gross
- Pre-deduction income amount
- net
- Amount remaining after all deductions
- rate
- Combined deduction rate as a percent (0 to under 100)
- fixed
- Flat fixed deduction subtracted as a dollar amount
How it works
- In Gross to Net mode, enter a gross amount, a combined deduction rate as a percent, and any flat fixed deduction. The calculator removes the percentage of gross, then subtracts the fixed amount, leaving your net.
- In Net to Gross mode, enter the net amount you want to keep. The calculator adds back the fixed deduction and divides by one minus the rate, solving for the gross figure required to net that target after the same combined deductions.
Worked example
Convert a $6,000 gross amount with a 28 percent combined rate and a $150 flat fixed deduction.
- Percentage deduction: 6,000 × 28% = $1,680.
- Subtract the percentage and the fixed amount: 6,000 − 1,680 − 150 = $4,170 net.
- Total deductions: 1,680 + 150 = $1,830, an effective rate of 1,830 ÷ 6,000 = 30.5%.
Net income is $4,170, with $1,830 in total deductions and an effective rate of 30.5%.
Frequently asked questions
- How is this different from a paycheck calculator?
- A paycheck or take-home pay calculator models pay frequency, the standard deduction, progressive federal brackets, and FICA separately, then splits the result across periods. This tool skips all of that. You provide one combined rate that already represents your blended deductions, so it is faster for quick what-if math but less precise than a full payroll breakdown.
- What rate should I enter?
- Use a single blended percentage that captures everything coming out as a proportion of gross: income tax, payroll tax, and any percentage-based contributions. If you know last period gross and net, divide total deductions by gross to get your real combined rate, then put fixed-dollar items like flat insurance premiums into the fixed field.
- How is the net to gross mode useful?
- When negotiating salary or pricing freelance work, you usually care about take-home money. Net to gross lets you start from the net you want to keep and back into the gross figure to ask for, so the same combined rate and fixed deductions still leave you with your target amount.
