Paycheck Calculation Formula Explained
Gross Pay Per Period:
GrossPerPeriod=AnnualIncome÷PayFrequency
Federal Tax:
FederalTax=AnnualIncome×(FederalRate÷100)
State Tax (Idaho):
StateTax=AnnualIncome×(StateRate÷100)
FICA Tax:
FICATax=AnnualIncome×(FICARate÷100)
Total Tax:
TotalTax=Federal+State+FICA
Net Annual Income:
NetIncome=AnnualIncome−TotalTax
Net Pay Per Period:
NetPerPeriod=NetAnnualIncome÷PayFrequency
Example Calculation
Let’s understand with a real-life example:
- Annual Income: $60,000
- Pay Frequency: Monthly (12)
- Federal Tax: 12%
- Idaho State Tax: 5.8%
- FICA: 7.65%
Step-by-step breakdown:
1. Gross Pay Per Month
$60,000 ÷ 12 = $5,000
2. Tax Calculations:
- Federal Tax = $7,200
- State Tax = $3,480
- FICA Tax = $4,590
3. Total Tax:
$7,200 + $3,480 + $4,590 = $15,270
4. Net Annual Income:
$60,000 − $15,270 = $44,730
5. Net Monthly Pay:
$44,730 ÷ 12 = $3,727.50
