Match the dinners on both sides
Choose the period, number of dinners, and servings per dinner before adding prices. Three evenings for two people means six dinner servings on each side. Keep breakfast, lunches, and household products outside the comparison unless you deliberately include equivalent costs for both options.
The meals do not have to be identical recipes, but choose alternatives you would actually consider. Comparing a kit with an imaginary grocery menu tells you little about the week you intend to eat.
Use the meal kit charge you would pay
Enter the food charge, delivery fee per box, number of boxes, and other charges included in your choice. Delivery belongs to the box, so one delivery fee should not be charged again for every serving inside it. Use zero for a genuinely free delivery.
Check whether an upgrade or extra item changes the amount on the bill. If you include it on the kit side, consider whether the grocery alternative covers the same meal or extra item. The calculator compares the costs you enter, not a provider’s current offers.
Choose what the grocery figure represents
Ingredient use cost values the amounts that go into those dinners. Shopping spend covers the packages you need to buy during this period. Select the meaning that matches your figure so the result explains the difference you are looking at.
A jar partly used in one sauce contributes only that portion to ingredient cost, but purchasing the jar requires the whole price. Food already at home can reduce this trip’s payment. Its use still has a value when you compare ingredient costs.
If you have package prices but no grocery total yet, the recipe cost calculator separates ingredient-use cost from the new packages you need to buy.
A six-serving comparison
Here is a price example: three dinners for two at $10 per serving, plus one $9 delivery, totals $69. If groceries used for the same six servings are valued at $24, the difference is $45 under the ingredient-use comparison.
If the actual packages you need to purchase cost $30, the spending difference is $39 instead. Both calculations are useful when labeled. Neither means you have already saved that amount, and neither describes prices at a particular supermarket or meal kit service.
Compare an ordinary week as well as an offer
Run a separate comparison for an introductory offer and the price you expect afterward. A discounted first box does not establish what later weeks cost. Revisit the figures when your serving count, delivery pattern, or chosen extras change.
If you pay for a planning service and want it included, add its actual cost for the same period. Keep unpriced convenience separate from the money totals. You may value choosing recipes, skipping the store, or using familiar ingredients even when that option costs more.
Price is one part of the decision. The meal planning vs. meal kits guide also compares shopping responsibility, delivery timing and changing your dinner plans.
