How to reduce restaurant food cost: 10 practical ways
To reduce restaurant food cost, first measure it — food cost percentage is what your ingredients cost divided by what you sold — then close the biggest leaks: dishes priced without a costed recipe, waste and spoilage, portions that drift, stock that disappears between counts and buying without a plan. The ten steps below cover each, in the order that usually saves the most.

What is food cost percentage?
Food cost percentage is the share of your food sales that went on ingredients:
Food cost % = cost of the ingredients used ÷ food sales × 100
For example, if a week's food sales were 10,000 and the ingredients used cost 3,000, food cost was 30%. Many full-service restaurants aim for somewhere around 28–35%, but the right target depends on your menu, your prices and your style of service — a steakhouse and a coffee shop will never match.
How to work it out for a week or a month
Use what was actually used, not what was bought:
Ingredients used = opening stock + purchases − closing stock
Count the stock at the start and the end of the period, add what you bought in between, and divide by the food sales for the same period. Do it every week at the same time and the trend tells you far more than any single number.
10 practical ways to reduce restaurant food cost
1. Cost every recipe
You cannot price a dish properly if you do not know what it costs to make. Write down every ingredient and its quantity for each dish, and keep the ingredient prices up to date. With recipe-based inventory software, every sale then takes those ingredients out of stock by itself, and each dish shows its real cost and margin.
2. Price on margin, not on habit
Once each dish has a cost, sort the menu by two questions: does it sell, and does it make money?
- Sells well, good margin — keep it, feature it, protect its quality.
- Sells well, poor margin — adjust the portion or the recipe, or raise the price a little.
- Sells poorly, good margin — give it a better place on the menu or a better description.
- Sells poorly, poor margin — rework it or take it off.
3. Standardise portions
A little extra rice or a larger piece of chicken on every plate adds up across a month. Use the same scoop, ladle and scale every time, put the portion on the recipe card and show photos of the finished plate in the kitchen.
4. Record every bit of waste
Ask the team to record what is thrown away and why — spoiled, over-produced, dropped, returned by a guest. A wastage log turns a vague feeling into a list you can act on: if the same prep item is thrown away every night, make less of it.
5. Watch expiry dates and rotate stock
First in, first out: new deliveries go behind older stock. Track expiry dates so you use items before they go off, and plan specials around what needs using.
6. Count stock regularly and investigate the gaps
Compare the stock you counted on the shelf with what the system says should be there. A difference, called variance, means something went wrong: a missed delivery, an unrecorded waste, a wrong recipe — or theft. Count your most expensive items more often than the rest.
7. Buy to a plan
Set a par level for each item — how much you need between deliveries — and order up to it with purchase orders instead of guessing. Check each delivery against the order before signing, and compare suppliers' prices regularly.
8. Make prep items properly
Sauces, pastes, doughs and marinades are made from other ingredients. Record each batch you prepare, so the raw ingredients leave stock and the finished prep item enters it. Otherwise prep becomes the place where stock quietly disappears.
9. Control voids, comps and cancellations
A cancelled dish, a free drink and a large discount are all food that left the kitchen without full payment. Require a reason, and a senior person's approval, for each, and review them weekly. A POS that writes every change into an audit log makes this simple.
10. Review the numbers every week
Look at food cost %, the biggest variances, the waste log and your most and least profitable dishes every week, at the same time. Small corrections made weekly beat a big surprise at the end of the month. A gross profit report in your restaurant accounting software puts these on one page.
A simple weekly food cost routine
- Count the high-value items on the same day each week.
- Compare counted stock with expected stock and note the biggest gaps.
- Read the waste log and change prep quantities where needed.
- Check the margin of your top ten dishes against last week.
- Review voids, discounts and cancellations.
- Place next week's orders against your par levels.
How software makes this easier
Doing all of this on paper is possible, but it is the reason most restaurants stop doing it. DotMax links recipes to sales, so stock comes off as you sell; records wastage, expiry and stock counts; shows the variance; runs purchase orders; and shows gross profit and menu profitability on your phone. It suits restaurants, cafés and bakeries with daily production alike. Plans and prices are on the pricing page.
The short version
To reduce restaurant food cost, measure it every week, cost every recipe and price on margin, standardise portions, record waste, count stock and investigate the gaps, buy to a plan and keep voids under control. None of it is complicated — what matters is doing it every week.
