Sales Tax Calculator

About This Tool

Look, I get it—sales tax is annoying. You see a price tag, think you know what you’re paying, and then bam, extra fees at checkout. This calculator? It’s just a simple way to figure out how much you’ll actually owe after tax. No fluff, no hidden steps. You punch in the price and the tax rate, and it spits out the total. That’s it. I built this because I got tired of doing mental math at the register. Or worse—getting home and realizing I forgot to budget for tax. This thing runs in your browser, doesn’t save your data, and won’t ask for your email. Honestly, it’s the kind of tool I wish more sites offered: useful, quiet, and gone when you’re done.

FAQ

Can I use this for business expenses?
Sure, why not? It’s not built for accounting software or tax filings, but if you’re estimating costs for a project or checking receipts, it’ll do the job. Just don’t rely on it for official records—always double-check with your accountant.

Why doesn’t it auto-detect my location’s tax rate?
Because tax rates change. A lot. And they vary by city, county, even specific items. Gas, groceries, clothes—they’re all taxed differently depending on where you are. I’d rather you enter the exact rate than get a wrong number from a database that’s six months out of date.
