Estimate your profit after platform fees, taxes, and business costs

Who These Calculators Are For

YieldCalcHub is built for people whose income arrives after somebody else takes a cut. If you sell on Etsy or Amazon, invoice clients through Upwork or Fiverr, or run a one-person business that files a Schedule C, your gross revenue and the money you actually keep are two very different numbers. The gap between them is made of marketplace commissions, payment processing, fulfillment and storage charges, unbilled hours, and the tax you owe on whatever survives.

Most people discover that gap the hard way: a $35 Etsy order that nets $22, a quarter that ends with an unexpected tax bill, an hourly rate that quietly turns into half of what was quoted. These tools exist to put those numbers in front of you before the money moves, using the published fee schedules and current federal tax figures rather than rules of thumb.

The Three Questions These Tools Answer

What do the platforms take? The Etsy Profit Calculator applies the four fees Etsy charges (a $0.20 listing fee, 6.5% on item price plus shipping, payment processing, and the offsite ads fee when it applies) and subtracts your own costs of goods, shipping, and packaging. The Amazon FBA Profit Estimator does the same for referral fees, fulfillment tiers, the fuel and logistics surcharge, and monthly storage, and it lists plainly which Amazon fees it does not model so you know where the estimate ends.

What will you owe? The Self-Employment Tax Calculator handles the 15.3% that self-employed people pay on 92.35% of net earnings, including the Social Security wage base and the Additional Medicare Tax. The Quarterly Estimated Tax Calculator works out Form 1040-ES payments using the federal safe-harbor rules, including the $1,000 general rule that means many people owe nothing quarterly at all. The Home Office Deduction Calculator covers the IRS Simplified Method at $5 per square foot up to the 300 square foot cap.

What is your rate really worth? The Freelancer Fee and Tax-Reserve Estimator takes your billed rate, removes platform and processing fees, applies the tax reserve percentages you choose, and then divides by every hour you actually worked, including proposals, revisions, and admin. That last step is what turns a $50 hourly rate into an effective rate you can compare against other work. For sellers outside the US, the VAT Calculator adds or extracts VAT at any rate, including the divide-by-1.20 step that catches people out.

How the Numbers Are Sourced and Checked

Every reviewed page carries a source table naming the exact document behind each figure, with the date it was last verified. Tax figures trace to IRS publications, forms, and inflation-adjustment releases; marketplace fees trace to the platforms' own published pricing pages. Where a value depends on your situation rather than a published rate, it is an editable input labelled as an assumption, not a number we invented on your behalf.

The calculation logic itself is published too. Our Calculation Validation page lists the formula version each tool runs, deterministic test cases with their exact expected outputs, boundary tests for the rules most likely to be got wrong, and a dated log of every material correction we have made. When we get something wrong, the fix is recorded there with a date rather than quietly changed. The Methodology page explains the process behind all of it, and every calculator carries a link to report an error against a specific formula version.

What These Tools Are Not

These are estimators for planning, not tax preparation software and not financial advice. They model federal rules and published fee schedules; they do not know your full return, your state, your credits, or the exceptions that apply to your specific situation. Each page states its own limitations next to the result, and for anything that affects a filing or a significant financial decision, a qualified professional is the right next step. Our disclaimer sets this out in full.

Where to Start

If you sell physical products, start with the calculator for your marketplace and read the matching guide beside it: Etsy Fees Explained or Amazon FBA Fees. If you invoice clients, start with the freelancer estimator and the freelancer net income guide. If your question is tax rather than fees, the tax guides cover self-employment tax, quarterly payments, the 2026 brackets, the standard deduction, the home office deduction, and the 1099-K threshold, each with worked examples and its own sources. Every guide links to the calculator that runs its math, and every calculator links back to the guide that explains it.
