From $85,000 of gross salary, $12,260 goes to pre-tax deductions and $15,957 to taxes. Your effective tax rate is 18.8%, meaning you keep 66.8% as cash. The gap between salary and take-home is 33.2%, which is typical.
Effective rate describes your overall burden; marginal rate is what the next dollar is taxed at — 22% federal plus 7.65% FICA plus 5% state. Use the marginal rate for every decision: a raise, a bonus, a deduction, or an extra 401(k) contribution. Use the effective rate only to understand where you stand overall.
Adding $2,550 a year to your 401(k) reduces taxable income, so at a 27% combined marginal rate the actual hit to your take-home pay is $1,862 a year — $72 per check. You save $2,550 and it costs you $1,862. Over 25 years at 7% that contribution compounds to roughly $172,140.
Model the retirement impactIf you have a high-deductible health plan, HSA contributions are deductible from federal and state income tax and — uniquely — from FICA when made through payroll. That makes the effective saving about 34.6%, higher than a 401(k) contribution. Growth is untaxed and qualified medical withdrawals are tax-free. After 65 it behaves like a traditional IRA for any purpose.
Budgets built on gross salary fail in month one. Your actual monthly cash is $4,732. Under the 50/30/20 frame that is $2,366 for needs, $1,420 for wants and $946 for savings and extra debt payments.
Build your budgetProperty tax rates, insurance costs and income tax vary enormously between states. These versions load local averages so you start from a realistic baseline.

That is worth roughly $3,685 a year compared with a 5% state. States without wage income tax typically recover revenue through higher property or sales taxes, so the total picture depends on your housing situation — Texas and New Hampshire in particular pair no income tax with among the highest effective property tax rates in the country.

From $60,000 of gross salary, $7,680 goes to pre-tax deductions and $10,487 to taxes. Your effective tax rate is 17.5%, meaning you keep 69.7% as cash. The gap between salary and take-home is 30.3%, which is typical.

Adding $1,800 a year to your 401(k) reduces taxable income, so at a 21.3% combined marginal rate the actual hit to your take-home pay is $1,417 a year — $54 per check. You save $1,800 and it costs you $1,417. Over 25 years at 7% that contribution compounds to roughly $121,511.
Model the retirement impactDeductions come out in a specific order, and the order determines how much tax you pay. Section 125 benefits — health, dental and vision premiums — come out first and are exempt from both income tax and FICA. HSA contributions made through payroll get the same treatment.
Traditional 401(k) contributions come out next. They reduce federal and state income tax but not FICA, which is why your Social Security wages on a W-2 are higher than your taxable wages. What remains after those deductions and the standard deduction is what federal brackets apply to.
Your effective rate is total tax divided by total income. Your marginal rate is what the next dollar gets taxed at. They are never the same, because earlier dollars were taxed in lower brackets.
Every financial decision uses the marginal rate. Whether a pre-tax contribution is worth making, what a raise is actually worth, whether a deduction helps — all of these depend on the rate applying to the affected dollars, which is the marginal one. The effective rate is only useful for understanding your overall burden. Confusing them is the most common source of bad tax reasoning.
A large refund means you overpaid all year and lent the government money at zero interest. A large balance due can trigger underpayment penalties. Neither is the goal; landing near zero is.
The current W-4 asks about total household income rather than allowances, which handles dual-income households far better than the old version. The IRS Tax Withholding Estimator is the accurate way to set it. Recheck after any of the events that reliably break withholding: marriage, a child, a second job, a spouse starting work, or significant self-employment income.
The gap between salary and take-home is commonly 25–35%. Budgets built on the gross figure fail immediately.
Decisions use the marginal rate. Applying the effective rate to a raise or a deduction understates the benefit substantially.
It is an interest-free loan to the government. Adjust the W-4 and take the money in your paycheck instead.
Each job withholds as if it were your only one, which reliably under-withholds for dual-income households.
It is the only account exempt from income tax and FICA on the way in, untaxed while growing, and tax-free coming out for medical costs.
A single filer contributing 8% to a 401(k) in a 5% state keeps roughly $57,000–60,000 in cash, plus about $6,800 going into retirement savings. In a state with no income tax the cash figure is around $3,000–3,500 higher. The exact number depends on your benefit elections, which is what the calculator above accounts for.
Between federal income tax withholding, Social Security at 6.2%, Medicare at 1.45%, state income tax, health premiums and retirement contributions, deductions commonly total 25–35% of gross pay. Pre-tax deductions are not lost — 401(k) and HSA money is still yours, it simply moves into an account rather than your checking account.
No. Brackets are marginal — only the dollars above each threshold are taxed at that bracket's rate. Earning one more dollar can never leave you with less after tax. Real cliffs exist in benefit phase-outs such as ACA premium subsidies and income-driven student loan repayment tiers, but never in the tax bracket structure itself.
Multiply the raise by one minus your combined marginal rate — federal plus 7.65% FICA plus state. At a 22% federal marginal rate in a 5% state, roughly 65% survives. A $10,000 raise delivers about $6,500 in additional take-home pay, or less if it pushes you across a bracket threshold partway through.
They are withheld differently, not taxed differently. Employers typically withhold supplemental wages at a flat 22% federal rate, which over-withholds for lower earners and under-withholds for higher ones. At filing, the bonus is simply ordinary income taxed at your actual rate, and the difference is settled through your refund or balance due.
Federal brackets, the standard deduction and FICA wage bases are for tax year 2025. State income tax is approximated from the top marginal rate rather than modeling each state's full progressive schedule, so the state figure is an estimate. Local income taxes — such as New York City's — are not included.
