Federal / CA / FICA (annual)
$15,007.00 · $6,071.14 · $8,262.00

Your combined marginal rate on the next dollar is about 39.0%, while your effective tax rate on all gross is about 27.2%. The gap is normal — lower brackets and deductions pull the average down.

Your annualized gross is about 38% above a static California average-wage benchmark (~$78,000/year).

Suggested next steps

  • This page is California-only by design — other states get their own URLs in Phase 2.
  • Compare biweekly vs monthly gross if your employer offers multiple pay schedules.
  • Pair with the Hourly to Salary Converter if you need to annualize an hourly CA wage first.

How the California paycheck estimate works

  1. Annualize your gross from the pay frequency (weekly 52, biweekly 26, semi-monthly 24, monthly 12).
  2. Subtract annual pre-tax contributions (for example, 401k) from wages used for income tax.
  3. Estimate federal and California income tax with simplified brackets and deductions.
  4. Add employee Social Security and Medicare.
  5. Net = gross − pre-tax − taxes; divide back to a per-paycheck figure.

The results panel explains effective vs marginal rates with rule-based copy and compares your gross to a static California wage benchmark (Section 15 free differentiation — no paid API).

Worked example

Semi-monthly gross $4,500, single, $6,000/year pre-tax:

  1. Annual gross = 4,500 × 24 = $108,000
  2. Income-tax wages ≈ 108,000 − 6,000 = $102,000
  3. Federal + CA + FICA are estimated from simplified tables
  4. Take-home per check = annual net ÷ 24

Effective rate might land in the high teens/low twenties while the combined marginal rate is higher — the tool spells out that gap in plain language.

Methodology and notes

Based on simplified 2026 planning brackets and FICA rates stored statically in the app. Not IRS/FTB software, not advice. Confirm withholding with your employer’s payroll system or a tax professional. All math runs in your browser.

Frequently asked questions

Why is this paycheck calculator California-only?

State income tax rules differ by state. Following our geo-SEO architecture, California gets its own indexable URL. Other states will ship as separate pages (for example, paycheck-calculator-texas) rather than a single dropdown.

What is the difference between effective and marginal tax rate?

Effective rate is total tax divided by gross pay — your average burden. Marginal rate is the combined rate on the next dollar of income (federal bracket + CA bracket + employee FICA in this simplified model). Effective is almost always lower than marginal because earlier dollars are taxed less.

Does this match my real paycheck exactly?

No. It’s an educational estimate using simplified 2026-style brackets, standard deductions, and flat FICA assumptions. Local taxes, benefits premiums, garnishments, and W-4 extras are not fully modeled.

How does the California average comparison work?

We compare your annualized gross to a static California average-wage benchmark stored in our reference data (not a live API). It’s a planning cue, not an official BLS release for your occupation.
