Meal prep costing is recipe costing at batch scale: add up every ingredient in the batch, then divide by the number of containers.
cost per meal = total batch cost ÷ number of containers
Example: chicken, rice and roasted veg for five containers totals £12.50 → £2.50 per meal.
Tips
- Weigh the cooked batch and divide evenly so each container matches the cost.
- Include sauces and oils — they're easy to forget across a big batch.
- Compare the result to what you'd usually spend on lunch.
