Net to Gross Calculator
Print| Total Withholding Tax Deductions | $0.00 |
A Net to Gross Calculator (also known as a Gross-Up Calculator) performs a reverse payroll calculation to determine the total gross salary, wage, or bonus an employer must pay so that an employee receives a specific target net take-home pay after all federal income taxes, state income taxes, and FICA payroll taxes are deducted.
Our free Net to Gross Calculator computes the exact required gross pay amount for regular salaries, executive relocation packages, contractor compensation, and net bonus payouts.
How to Calculate Gross Pay from Target Net Pay (Gross-Up)
Reversing net pay to gross salary requires adding up all applicable federal, state, and payroll tax rates to determine the net retention percentage.
The Basic Paycheck Gross-Up Formula:
Combined Tax Rate = Federal Income Tax Rate % + State Income Tax Rate % + FICA Social Security Rate (6.2%) + FICA Medicare Rate (1.45%)
Net Retention Rate % = 100% - Combined Tax Rate %
Required Gross Salary = Target Net Take-Home Pay / ( Net Retention Rate % / 100 )
Supplemental Flat Tax Gross-Up Formula (For Bonuses):
For supplemental bonus gross-ups, federal flat tax rates (22% standard / 37% over $1M) simplify the formula:
Gross Bonus = Desired Net Bonus / [ 1 - ( 22% Fed + 7.65% FICA + State Supplemental Rate % ) ]
Target Net Pay to Required Gross Salary Reference Table
The table below shows required gross salaries needed to yield specific target net take-home pay amounts across standard combined tax rate assumptions:
| Target Net Take-Home Pay | 20% Combined Tax Rate | 30% Combined Tax Rate | 40% Combined Tax Rate | Total Tax Gross-Up Added |
|---|---|---|---|---|
| $1,000 Net Paycheck | $1,250.00 | $1,428.57 | $1,666.67 | $250 – $667 |
| $2,500 Net Paycheck | $3,125.00 | $3,571.43 | $4,166.67 | $625 – $1,667 |
| $5,000 Net Monthly Pay | $6,250.00 | $7,142.86 | $8,333.33 | $1,250 – $3,333 |
| $10,000 Net Bonus Payout | $12,500.00 | $14,285.71 | $16,666.67 | $2,500 – $6,667 |
Step-by-Step Calculation Example
An employer wants to grant a key employee a net $5,000.00 cash bonus payout after all taxes. The employee’s marginal tax rates are:
- Desired Net Cash Bonus: $5,000.00
- Federal Supplemental Flat Tax Rate: 22.0%
- FICA Social Security Tax: 6.2%
- FICA Medicare Tax: 1.45%
- State Supplemental Tax Rate: 5.0%
Step 1: Compute Combined Effective Tax Rate
Combined Tax Rate = 22.0% (Fed) + 6.2% (SS) + 1.45% (Med) + 5.0% (State) = 34.65%
Step 2: Compute Net Retention Percentage
Net Retention Rate = 100% - 34.65% = 65.35% (0.6535)
Step 3: Compute Required Gross Bonus Amount
Gross Bonus = $5,000.00 / 0.6535 = $7,651.11
Verification:
Deducting 34.65% tax ($2,651.11) from a gross bonus of $7,651.11 leaves the employee with an exact net bonus check of $5,000.00.
Frequently Asked Questions (FAQ)
When do employers use a Gross-Up calculation?
Employers use gross-up calculations when offering spot bonuses, executive relocation stipends, tuition reimbursements, employee gifts, or severance packages where the company wants the employee to receive a clean, exact net dollar amount.
Is a grossed-up tax payment reported on IRS Form W-2?
Yes. Both the gross payment amount and the additional tax paid by the employer on behalf of the employee must be included in taxable gross wages on Form W-2 (Boxes 1, 3, and 5).
How do pre-tax deductions affect a Net to Gross calculation?
Pre-tax deductions (such as 401k or HSA contributions) reduce the taxable portion of gross wages, allowing employers to pay a slightly lower gross salary to achieve the same target net pay.
