Tariff went up? See your new sell price two ways: keep your profit or keep your margin. One-time purchase. No ads. No data collected. Skip the spreadsheet. Run the numbers. Cost changed? Customer wants a better price? Tariff went up? MarginKeeper is a pricing calculator built for the moment you need the answer, not when you're back at your desk. FOUR TOOLS. ONE TAP. Find Sell Price Enter your cost and target margin. MarginKeeper gives you the sell price and the profit behind it. Then use the slider to try a higher or lower price and watch your margin and profit update. Find Margin Already have a price? Enter your cost and sell price to see the margin you're really making and the profit per unit. Find Discount Putting something on sale? Enter the original price and the sale price to see the discount percentage and the amount off. Include Tariff A tariff changed your cost. Enter your product cost, tariff and margin, then choose: • Keep Profit: hold your profit per unit steady and see how much margin you give up. • Keep Margin: protect your margin percentage and see the new sell price and profit. See the price, profit and margin before and after the tariff, and exactly how much each one changed. MARGIN, NOT MARKUP MarginKeeper calculates true margin: profit as a percentage of the sell price. A product that costs 10.50 and sells for 42.00 has a 75% margin, not a 300% one. ONE APP. EVERY CURRENCY. No currency settings. No conversions. Just enter your numbers. MarginKeeper uses plain numbers, so it works with whatever currency your business uses. BUILT FOR • Sales teams quoting on the spot • Business owners setting prices • Importers and exporters dealing with tariffs and duties • Resellers, wholesalers and makers pricing their products YOUR NUMBERS STAY WITH YOU No account. No ads. No tracking. MarginKeeper doesn't collect any data. One-time purchase. No subscription. Questions or feedback: support@marginkeeper.com
