Paycheck inputs
How do you get paid?
i
Income mode
Most people know an annual salary or hourly rate better than gross per check. Pick the mode that matches what you know — we derive gross wages for each paycheck from that. |
|
|---|---|
Annual salary ($)
i
Annual salary
Your yearly wage before taxes (what the offer letter or raise usually quotes). Gross per check = salary ÷ pay periods. |
|
Hourly rate ($)
i
Hourly rate
Base hourly wage. Combined with hours per week and pay frequency to estimate gross per check (no overtime modeled). |
|
Hours per week
i
Hours per week
Typical scheduled hours. Weekly pay = rate × hours; other frequencies scale from a 52-week year. |
|
Gross pay per paycheck ($)
i
Gross per paycheck
Wages before taxes on one stub — useful if you’re matching an existing paycheck. |
|
Pay frequency
i
Pay frequency
How often you are paid. We annualize wages, estimate yearly tax, then divide back per check. |
|
Filing status
i
Filing status
Used for federal brackets/standard deduction and state brackets that differ for joint filers. |
|
Pre-tax deductions / paycheck ($)
i
Pre-tax deductions
401(k), traditional HSA/FSA-style amounts per paycheck that reduce income-tax wages in this sketch. Social Security and Medicare still use full gross (typical for elective deferrals). |
How to use this calculator

- Enter that income figure (and hours/week if hourly), then pay frequency.
- Select filing status and any pre-tax deductions per paycheck.
- Read estimated gross per check, taxes, and take-home pay.

How the estimate is built
Annual gross = pay × periods. Federal taxable ≈ annual gross − pre-tax − federal standard deduction. Federal tax from TY2026 brackets. State tax from this state’s pack. FICA: 6.2% SS up to $184,500 + 1.45% Medicare (+ 0.9% Additional Medicare above the filing-status threshold). Per-check taxes = annual ÷ periods. Net ≈ gross − pre-tax − federal − state − FICA.
Example scenario
Biweekly $3,200 with $200 pre-tax, married filing jointly — joint federal and Idaho standard deductions apply, Idaho taxes taxable income at 5.3%, and FICA uses the 2026 Social Security wage base.
FAQ
Is Idaho really flat?
Idaho uses a single-rate individual income tax (5.3% in this TY2026 pack) on taxable income after deductions — not a multi-bracket wage table.
Is this the same as my paycheck?
Not always. Employers use IRS Publication 15-T withholding methods, W-4 step settings, local taxes, benefits, and YTD FICA caps. We estimate annual liability and divide by pay periods.
Do pre-tax 401(k) contributions reduce FICA?
Elective deferrals generally still face Social Security and Medicare. This calculator reduces income-tax wages only.
Tax year?
Tables are encoded for tax year 2026 (federal Rev. Proc. 2025-32 inflation adjustments and the state packs noted on the page).
