How to Use the Near-Expiry Discount Savings Calculator
Grocery stores and delis often mark down items nearing their expiry date by 50% or more, but chasing the discount alone can backfire. This calculator weighs both sides — not just how cheap the item is, but whether you can realistically finish it within the days left — to show your true savings. No matter how big the price gap is, throwing away food you couldn't finish turns a discount into a loss.
When estimating the days you'll need, be realistic about how often and how much of that item you actually eat. A single person buying a family-size pack of fresh produce at a markdown price often ends up needing more days than planned, simply because consumption doesn't scale up that fast. If the item is meat or fish that freezes well, portioning and freezing it right after purchase can effectively extend your usable window well beyond the printed date, regardless of the days left on the label.
On the other hand, items that don't freeze well — dairy, prepared salads, cut produce — are safer to buy only in amounts you can finish before the printed date. Before grabbing anything from the markdown shelf, asking "can I really eat all of this in time" matters more than asking "how deep is the discount."
Frequently Asked Questions
If your estimated days needed exceeds the days left, check whether the item can be frozen. Fresh items that can't be frozen carry a high risk of going to waste, which turns your discount into a loss.
No. No matter how deep the discount, throwing away food you didn't finish in time means losing close to the full regular price, not saving money. Whether you can realistically eat it all matters more than the discount percentage.
