How it works
paycheck deductions calculator takes your inputs and produces take-home after deductions, total deductions, retirement deduction. Break down every withdrawal from your paycheck — health, dental, vision, retirement percentage and other deductions — into one clear picture. You provide 6 inputs: Gross pay (monthly) (currency, in dollars) (default: 6000 dollars); Health insurance premium (currency, in dollars) (default: 250 dollars); Dental premium (currency, in dollars) (default: 40 dollars); Vision premium (currency, in dollars) (default: 15 dollars); Retirement contribution (percent, in percent) (default: 6 percent); Other deductions (currency, in dollars) (default: 0 dollars). The calculator returns 3 outputs: Take-home after deductions (the primary result); Total deductions (a secondary output); Retirement deduction (a supplementary figure). Personal finance decisions trade off today's comfort against tomorrow's security. The numbers behind that trade-off — how much to save, spend, borrow, or insure — are what this calculator makes concrete. Rather than rules of thumb, it gives you the actual arithmetic for your situation so you can compare options side by side and decide with confidence. The underlying formula: Retirement = Gross x retirement% | Take-home = Gross - health - dental - vision - retirement - other With the default values, take-home after deductions is computed from the interaction of every input field — change any one of them and the result updates immediately, so you can stress-test different scenarios without re-entering the whole form. Adjust the inputs to match your real financial situation. The defaults are realistic starting points, but every person's circumstances differ — your actual income, expenses, rates, and timelines will produce a different answer. Use the tool iteratively: start with the defaults, then change one variable at a time to see which factor has the largest impact on your outcome.Formula
Retirement = Gross x retirement% | Take-home = Gross - health - dental - vision - retirement - other
Tips
- Every 1% of retirement contribution is a decision made permanent — review at every open enrolment.
- HSAs beat flexible spending for many: unused balances roll over, and contributions are triple-tax-advantaged.
- Compare benefit packages across job offers in dollars, not percentages — this tool makes that concrete.
- Check that 'other' line — small recurring deductions hide there and are often cancelable.
Frequently asked questions
Which deductions come out before tax?
Health, dental and vision premiums, retirement contributions to 401(k)-style plans, HSAs and flexible spending accounts are pre-tax: they reduce your taxable income. That matters, because the effective cost of each pre-tax dollar is about 22-30% less than its face value depending on your bracket.
How much should I contribute to my 401(k)?
At minimum, enough to capture the full employer match — that is an immediate 50-100% return. Beyond the match, most planners suggest 10-15% of income toward retirement overall, split across accounts. The Retirement Calculator can show what that percentage builds by your target age.
Why is my take-home different from this calculation?
Taxes are the missing layer — federal, state and FICA withholding. Run the same gross through the Take-Home Pay calculator (which applies tax rates) and combine both views for the complete picture.
