Gross Pay: What You Earn Before Deductions
Gross pay is the total amount you earn before anything is taken out. How it's calculated depends on how you're paid:
Hourly employee: Hours worked x hourly rate (plus overtime, if applicable)
Salaried employee: Annual salary divided by # of pay periods (weekly, biweekly, etc)
Bonuses or commissions: These may appear as separate line items and can be taxed differently.
Tip: Take a look at the pay period this paycheck covers. Verify you were paid correctly for your time, overtime, or performance incentives.
Pre-Tax Deductions: Reducing Your Taxable Income
Some deductions are taken out before taxes (pretax), which lowers your taxable income today. Common pre-tax deductions include:
Health, dental, vision insurance premiums
Retirement contributions (401(k), 403(b))
Flexible Spending Accounts (FSA) or Health Savings Accounts (HSA)
**Your first paycheck of the new year may show increased insurance premiums, lowering your take home pay.
Tip: If you're looking to reduce your tax liability, you may be able to increase contributions to your pre-tax deductions.
Employee Taxes
Taxes are often the largest deduction on a paycheck. You'll typically see:
Federal income tax: Based on your earnings and the information you provided on your W-4
State and local taxes: Varies by location - some states have no income tax
OASDI/FICA/Social Security: A fixed percentage of your gross wages (6.2%) up to an annual limit ($184,500)
Medicare tax: A smaller percentage (1.45%), with an additional surtax for high earners (additional 0.9% for income above $200k single filters, $250k MFJ)
**There are some nuances with taxes. Although pre-tax deductions are not subject to income tax, some items (401(k), 403(b), etc) are subject to Social Security and Medicare tax.
Tip: You can update your W-4 to change tax withholdings so you don't owe more at tax filings. Consult with a tax expert before making a change.
Post-tax Deductions: Taken After Taxes
Some deductions are taken out after taxes (post-tax) have already been calculated. These might include:
Roth Employer Sponsored Retirement Accounts
Life or disability insurance not offered pre-tax
Union dues or wage garnishments
Tip: Consult with a financial or tax professional to see if it makes sense to contribute more towards post-tax deductions or pre-tax deductions.
Net Pay: What You Actually Take Home
This is also called "take-home pay" which is what's left after all deductions. This is the amount deposited into your bank account or printed on your check.
Tip: While it's tempting to focus only on this number, understanding how you got there is key to managing your money effectively.
Year-to-Date (YTD) Totals: The Bigger Picture
Most paychecks include year-to-date (YTD) figures showing your gross pay, taxes paid, and take home pay. These totals are helpful for:
Tracking progress towards retirement contribution limits
Estimating your annual income
Proactive tax planning
Taking a few minutes to review your paycheck can help you:
Catch mistakes in pay, hours, or deductions
Plan your budget based on your net income
Prepare for taxes and avoid surprises
Optimize your employer benefits
Your paycheck is a financial tool. By learning how to read it, you can make proactive financial decisions today to build yourself a secure financial future.
