What does "break-even quantity" mean for a coupon?+
It's the number of units you need to buy for the coupon's total discount to equal or exceed any extra cost of buying in that quantity, such as a bulk-size premium or a minimum purchase requirement tied to the coupon.
How does a minimum-purchase coupon change the calculation?+
For a "$10 off $50" style coupon, the break-even question is whether the items you actually need add up close to $50 without unnecessary padding — buying extra items just to hit the threshold can erase the discount's value if those items go unused.
Does buying more than the break-even quantity make sense?+
Only if you'll actually use or can store the extra units before they expire or go to waste; beyond the break-even point, additional units purchased just to "maximize the coupon" often cost more than the savings they generate.
How do stacking store discounts with a coupon affect break-even?+
If a store discount already reduces the price before the coupon applies, recalculate the break-even quantity using the post-discount price, since the coupon's relative value shrinks once the base price is already lower.
What's a common mistake people make with bulk coupons?+
Assuming the coupon is worth using regardless of quantity — the calculator often reveals that buying just one or two units below the coupon's intended trigger point is cheaper overall than buying extra just to qualify for the discount.
