When to use this calculator
- Before accepting a pay change, bonus or contribution arrangement.
- When you want a simple take-home or conversion estimate before payroll or filing.
- When you need to convert between hourly, monthly and annual pay.
- When you want to compare two pay scenarios using the same assumptions.
A realistic US planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
| Input | Value |
|---|---|
| Capital Gain ($) | 50000 |
| Holding Period | Short-term (held ≤ 1 year) |
| Filing Status | Single |
| Other Taxable Income ($) | $55,000 |
After entering these figures, review federal cgt, niit (3.8%) and state tax together rather than in isolation. Then rerun the tool with one input adjusted.
How to read your results
Federal CGT
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
NIIT (3.8%)
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
State Tax
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.
Total Tax
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.
Effective Rate
The effective rate lets you compare options on a like-for-like basis rather than being misled by different compounding periods or fee structures.
Net Proceeds
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Method & assumptionsAuthoritative sources
This calculator applies the 2024 federal capital gains schedule. Short-term gains are taxed as ordinary income — federal tax is estimated by computing the marginal bracket difference between your other income alone and your other income plus the gain. Long-term gains use the preferential 0%, 15%, and 20% tiers based on taxable income and filing status. The 3.8% Net Investment Income Tax applies to long-term gains when modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly), per ACA rules.
State tax is applied as a flat rate on the full gain — enter your state’s effective rate for a blended estimate. The calculator does not model AMT, depreciation recapture on real property (25%), or collectibles (28%). The effective rate is total tax divided by the reported gain. Results are estimates only; consult a CPA or enrolled agent before filing.
Common mistakes
- !Using an assumption that is not supported by a current local quote, bill, statement or official source.
- !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- !Mixing monthly and annual inputs without converting them consistently.
- !Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
