Add things to your basket as you shop and watch the total — set a budget and we'll tell you how much you've got left before the till does. All on your device, nothing saved.
A running tally to keep you in control at the shop — final price at the till may differ with offers, weighed items and any discounts.
How to stick to your shopping budget
The supermarket total at the till can be a nasty surprise. This calculator lets you add items to a running basket as you shop, set an optional budget, and see in real time how much you've spent and how much you've got left — so you stay in control before you reach the checkout.
It's a simple way to avoid overspending: see the total climb as you add things, and get a clear warning the moment you go over budget. Pair it with a shopping list and own-brand swaps and it's an easy way to keep weekly food spending down.
Everything runs in your browser and nothing is saved. The final till price may differ slightly with multi-buy offers, loyalty prices and weighed items.
Frequently asked questions
How can I stick to a food shopping budget?⌄
Set a budget before you go, shop with a list, and track your basket total as you add items so you can put something back before the till — not after the shock.
Does it account for offers and loyalty prices?⌄
No — it adds up the prices you enter. Multi-buys, loyalty discounts and weighed items mean the final till price can differ slightly, so leave a little headroom.
How can I cut my grocery bill?⌄
Plan meals around what's on offer, switch to own-brand basics, check the price per 100g rather than the sticker price, and avoid shopping while hungry.
Can I use it for any shop?⌄
Yes. It works for any shopping trip — supermarket, market or online basket — wherever you want a running total against a budget.
Is my shopping list saved?⌄
No. It stays on your device for the session and nothing is uploaded or stored.
