Business Calculators
Free business calculators: profit margins and markup, sales commissions, freelance rates, and self-employment tax — price your work with confidence.
Freelance Rate Calculator
Converting a salary expectation into a freelance hourly rate is more than dividing by hours — self-employment tax, expenses, and unpaid time all take a cut. This calculator works backward from the income you want.
Margin & Markup Calculator
Price your products so you actually make money. Enter cost and selling price to see profit per unit, margin, and markup — and understand the difference between the two.
Commission Calculator
Real estate, car sales, SaaS, freelance referrals — know what a deal actually pays you. Enter the sale and your rate to see commission and total earnings.
