Is 30% Off or $30 Off a Better Deal?
The answer flips at exactly $100 — cheaper items favor the dollars, pricier items favor the percent.
At a glance
The Breakeven Price Is $100
Thirty percent of $100 is exactly $30, so at a $100 sticker the two coupons are identical. Below $100, $30 off wins; above $100, 30% off wins — and the gap widens as the price moves away from the breakeven in either direction.

Why Fixed Coupons Punch Above Their Weight on Cheap Items
A fixed $30 off is worth 60% on a $50 item but only 10% on a $300 item. That is why stores attach minimum-purchase rules to dollar coupons — without one, shoppers would apply them to the cheapest eligible item for a massive effective percentage. Enter any price in the calculator above with each discount type to compare your exact numbers.
Watch the Fine Print
- Minimum spend requirements can force you to buy more than you planned, erasing the savings.
- Some coupons exclude sale items, so a 30% code may not stack on an already-marked-down price.
- Compare the final checkout price including shipping and tax, not the discount headline.
Frequently Asked Questions
How do I compare a percent off versus dollars off quickly?
Find what the percentage is worth in dollars at your price. If 30% of the price is more than $30 — anything over $100 — take the percentage deal; otherwise take the fixed $30.
What percent is $30 off on a $75 item?
$30 ÷ $75 = 0.40, so it is a 40% discount. Divide the dollar savings by the original price and multiply by 100.
Can I use both a percentage code and a dollar coupon?
Most retailers allow only one promo code per order, though a dollar-off coupon sometimes stacks with an automatic sale. Test the final price in the cart before assuming both apply.
Which discount type do stores prefer to offer?
Dollar-off coupons with minimum spends, because they look generous on small purchases while costing less than a percentage on large ones, and the minimum pushes up order size.
