Your combined federal + state marginal tax rate, not effective rate.
How to Use This Tool
Follow these steps to calculate your raise impact:
- Enter your current annual gross salary in the first input field.
- Select whether your raise is a percentage of your current salary or a flat dollar amount.
- Enter the raise value (percentage or dollar amount) in the corresponding field.
- Choose your pay frequency from the dropdown to see per-pay period amounts.
- Enter your estimated marginal tax rate (federal + state combined) to calculate take-home pay.
- Click "Calculate Raise" to see a full breakdown of your new pay and take-home amounts.
- Use the "Reset" button to clear all fields and start over.
Formula and Logic
This calculator uses standard personal finance formulas to compute raise impacts:
- Raise Amount: If percentage-based: Current Salary × (Raise % / 100). If flat: entered dollar amount.
- New Annual Salary: Current Salary + Raise Amount.
- Take-Home Pay: Annual Salary × (1 - (Marginal Tax Rate / 100)). This uses your marginal rate, which applies to your highest tax bracket, not your effective overall tax rate.
- Per-Pay Period Amounts: Annual Salary divided by the number of pays per year (52 for weekly, 26 for bi-weekly, 24 for semi-monthly, 12 for monthly).
- Monthly Amounts: Annual Salary divided by 12, regardless of pay frequency.
Practical Notes
Keep these real-world factors in mind when using this calculator:
- Marginal tax rates are tiered: only income above a certain threshold is taxed at the highest rate, so your effective tax rate will be lower than your marginal rate. Use marginal rate here for accuracy on raise impacts, as raises typically push income into the same or higher bracket.
- Pre-tax deductions (401k, health insurance, HSA contributions) reduce your taxable income, so your actual take-home may be higher than calculated if you have significant pre-tax deductions.
- Cost-of-living adjustments (COLAs) may offset raise impacts if inflation is high: a 3% raise with 4% inflation results in a net loss of purchasing power.
- Some employers prorate raises for mid-year hires: if you started halfway through the year, your first year raise impact will be lower than calculated.
- Bonus structures, commissions, and overtime are not included in this calculation: add these separately if they make up a portion of your income.
Why This Tool Is Useful
This calculator helps you make informed financial decisions in real-world scenarios:
- Job seekers can compare offer salaries with current pay to see real take-home differences.
- Employees can model raise requests to meet specific budget goals (e.g. saving for a house, paying off debt).
- Financial planners can use it to adjust client budgets for expected salary increases.
- It breaks down impacts across pay frequencies, so you can see exactly how much extra you'll get per paycheck, not just annually.
- Tax-adjusted take-home calculations help you avoid overestimating your raise's impact on your monthly budget.
Frequently Asked Questions
What's the difference between marginal and effective tax rate?
Marginal tax rate is the rate you pay on your last dollar earned, while effective tax rate is the average rate you pay on all your income. Use marginal rate here because raises apply to income in your highest current or new bracket.
Should I include bonuses in my current salary?
Only include regular, guaranteed bonuses in your annual salary. Variable bonuses or commissions should be calculated separately, as this tool assumes a fixed annual income.
How do pre-tax deductions affect my take-home pay?
Pre-tax deductions (401k, health insurance, FSA) reduce your taxable income, so your actual take-home pay will be higher than the calculator's estimate if you have these deductions. To adjust, subtract your annual pre-tax deductions from your salary before entering it.
Additional Guidance
Use this calculator as part of a broader financial planning process:
- Add extra take-home pay to your monthly budget to allocate towards savings, debt repayment, or discretionary spending.
- Compare raise scenarios (e.g. 3% vs 5% raise) to see how small percentage changes add up over time.
- Factor in raise impacts on benefits: higher salary may increase 401k matching contributions or life insurance coverage limits.
- Revisit this calculation annually to adjust for cost-of-living changes, promotions, or tax law updates.
