About PriceOffr
PriceOffr was built by an independent developer who got tired of discount calculators that took five seconds to load, served three banner ads, and asked for cookie consent before answering a question that needs about 40 lines of JavaScript to solve. The goal here is simpler: type a price, type a percentage, get an answer. No tracking, no popups, no email capture, no "subscribe for more deals."
What it does
The calculator runs in three modes:
- Sale Price Calculator: Takes an original price and a discount percentage and returns the sale price plus the dollar amount saved.
- Reverse Calculator: Takes a sale price and an original price and tells you what discount percentage was applied — useful for verifying advertised deals.
- Recovery Mode: Takes a sale price and a known discount percentage and returns the original price, handy when you want to know what something used to cost before the markdown.
How it works
Everything runs client-side in your browser. There is no server processing your numbers, no database logging your queries, and no analytics tracking what you calculated. The math happens in JavaScript on the page you're already looking at, which is why results appear instantly without a loading state.
The site doesn't require you to pick a currency. The percentage math is identical whether you're working in dollars, euros, pounds, yen, rupees, or rand — the calculator just applies the formula and returns a number. Format and currency symbol are up to you.
Accuracy
Calculations use standard floating-point arithmetic and round to two decimal places for display. For purchases under $10,000 this is accurate to the cent. For larger figures, expect rounding artifacts in the final decimal place — if you're calculating discounts on real estate or commercial transactions, verify with your actual contract numbers rather than treating this as authoritative.
