FAQ
What can this calculator help with?
It covers four of the most common pricing questions: what does an item cost after a discount, what was the original price before a discount, what should I sell something for if I want a certain markup on top of cost, and what should I sell something for to hit a target profit margin. Pick the tab that matches your question, enter two numbers, and the answer appears immediately with a plain-English sentence explaining it.
FAQ
What's the difference between markup and margin?
Markup is the percentage added on top of cost. If something costs 10 and you mark it up 50%, you sell it for 15 (10 + 5). Margin is the profit as a percentage of the selling price. If something costs 10 and you want a 40% margin, you sell it for about 16.67 (the profit of 6.67 is 40% of 16.67). Markup and margin give different selling prices even when you use the same percentage — they're different formulas, so pick the tab that matches how you're thinking about the problem.
FAQ
How do I find an original price from a sale price?
Use the "Original price" tab. Enter the sale price (what the item costs now) and the discount percentage that was applied. The calculator works backward to show what the price was before the discount. This is useful when you see a price on sale and want to know if the original price was really that high, or when you need to reverse-engineer a list price from a discounted offer.
FAQ
Does the calculator work on mobile?
Yes. The inputs stack on small screens, the tab pills wrap cleanly, and the result appears immediately after you type — no submit button, no page reload. Everything runs in your browser.
