What Is Portion Math?
Portion math is the art of breaking down a recipe’s total cost into a single serving price. The formula is simple:
Cost per serving = Total recipe cost ÷ Number of servings
For example, a casserole that costs $12 to make and yields 4 servings costs $3 per serving. Compare that to takeout, which can run $15 per meal. The difference is staggering.
Here’s a quick table to illustrate:
| Recipe | Total Cost | Servings | Cost per Serving |
|---|---|---|---|
| Chicken Stir-Fry | $8.50 | 4 | $2.13 |
| Beef Stew | $10.00 | 6 | $1.67 |
| Veggie Pasta | $5.00 | 4 | $1.25 |
By calculating these numbers, you can instantly see which recipes give you the best bang for your buck.
Step-by-Step Guide to Converting Recipes
Follow these steps to turn any recipe into an affordable meal plan:
- Step 1: List all ingredients with quantities. Write down each item and how much you need (e.g., 2 chicken breasts, 1 cup rice).
- Step 2: Determine unit costs. Divide the package price by the number of units. For example, a $4 bag of rice with 20 servings costs $0.20 per serving.
- Step 3: Calculate total recipe cost. Add up the cost of each ingredient based on the amounts used.
- Step 4: Divide by servings. Use the formula to find your cost per serving.
- Step 5: Adjust portion sizes. If a serving is too large, reduce it by 25% to lower the cost even further.
This method works for any dish — from soups to casseroles.
How to Build an Affordable Weekly Meal Plan
Start by selecting 5–7 recipes with a low cost per serving. Aim for meals under $2.00 per serving for maximum savings. Then, group similar ingredients to reduce waste.
For instance, if you buy a bag of carrots, use them in a stir-fry, a soup, and a salad across the week. This technique is called “ingredient overlapping” and it cuts costs by up to 30%.
To keep your savings organized, use a money saving binder like the NICOOTH 100 Envelopes Money Saving Binder. It features 100 pre-numbered envelopes to track your $5,050 savings goal while you build your meal plans.
