Meal Prep Budgeting FAQ
Everything you need to know about calculating, managing, and reducing your weekly food costs.
To calculate your cost per meal, add up the total cost of all ingredients purchased for your meal prep session, then divide that number by the total number of individual meals you prepared. For example, if you spent £40 on ingredients and made 10 meals, your cost per meal is £4.00.
Yes, significantly. The average purchased lunch costs between £8 and £15. A home-prepared meal typically costs between £2.50 and £5.00 per serving. Prepping 5 lunches a week can save you £25 to £50 weekly, or over £1,500 annually.
A realistic weekly grocery budget for one person meal prepping in the UK ranges from £30 to £60, depending on dietary preferences (e.g., vegetarian vs. meat-heavy) and whether you buy premium or staple ingredients. For a family of four, this typically scales to £80–£150 per week.
You can reduce meal prep costs by buying ingredients in bulk, choosing seasonal produce, incorporating plant-based proteins (like lentils and beans) which are cheaper than meat, planning meals around weekly supermarket offers, and minimising food waste by using leftovers creatively.
