Subtract the lower price from the higher price, divide that number by the higher price, and multiply by 100. For example, if your non-member price is $526 and your member price is $420, the discount is (526 − 420) ÷ 526 × 100 = 20.1520%. The Find Discount % tab above does this instantly and gives you the exact number to enter into your coupon code settings.

In many e-commerce setups — especially for camps, programs, and membership-based organizations — the member price and non-member price don’t divide into a clean whole number percentage. If you round to the nearest whole number, the customer either pays slightly more or slightly less than the intended price. This tool gives you the exact percentage down to four decimal places so the final checkout price matches what you advertised.

Even if you don’t have member vs. non-member pricing, the Value of % tab lets you quickly experiment with different discount percentages and instantly see the actual dollar-and-cents savings. This is useful when planning promotions, comparing coupon offers, or communicating real savings amounts to customers. You can test multiple scenarios in seconds without setting anything up in your store first.

Markup is based on your cost — it’s how much you add on top. Margin is based on the selling price — it’s the percentage of the sale that is profit. A 50% markup on a $20 item gives a $30 selling price, but the profit margin is only 33.3% because $10 profit is one-third of the $30 price. The Price Markup tab calculates both numbers for you so there’s no confusion when setting prices.

Many e-commerce stores — especially those selling camp registrations, program enrollments, or event tickets — set the decimal places to 0 so prices display as clean whole numbers like $420 instead of $420.80. When you enable this toggle, the calculator rounds the final price to the nearest whole number and shows you the exact value before rounding for reference.
