Better Than SmartAsset — Free Calculators That Show Their Work
SmartAsset returns a clean number — your estimated self-employment tax — and then tries to match you with a financial advisor. This page is for the freelancer who wants to see the formula, not the sales funnel. Reise shows every step: net SE income, the 92.35% SE earnings adjustment, the 15.3% split between Social Security and Medicare, the half-SE deduction, and bracket-by-bracket federal tax.
What makes Reise different
- Shows its math step by step so you can audit every number.
- Always free, with no account wall between you and the estimate.
- Built for 1099 contractors who need practical planning, not vague averages.

FAQ
What does Reise show that SmartAsset does not?
SmartAsset returns a number and an advisor-match CTA. Reise returns the same number plus the formula that produced it — line-by-line SE tax math, the half-SE deduction, federal bracket breakdown, and the effective rate.
Can I trust the math versus SmartAsset's calculator?
Yes. Every equation is cited to the IRS source (Schedule SE, Form 1040, Publication 334). You can read the formula panel and verify each step yourself — something SmartAsset's output does not let you do.
Is there an advisor matching or lead-capture flow?
No. There is no advisor network, no email capture, no phone number collection. Just the calculator.
How often is this updated?
Tax tables and thresholds are updated each year to match the current IRS guidance. The calculator currently uses 2024 values.
