How meal kit vs groceries cost is worked out
A meal kit and a grocery run are priced on the same serving, so the price per serving is the only money difference. The kit costs the servings times the kit price, plus the shipping for the week, and the groceries cost the servings times the grocery price per serving. The annual cost is the weekly cost times 52, and the 5-year cost is the annual cost times 5. The effective kit price per serving is the kit price plus the shipping divided by the servings, because shipping is spread across the whole box. The time is the servings times the cook time, plus the shopping trip for groceries, and the time saved is the grocery time minus the kit time. The winner on money is the smaller weekly cost; once time is valued, the winner is the side with the smaller cost after the saved time is priced.
At the defaults — 6 servings a week, kit $9.99 a serving, groceries $4.50 a serving, shipping $9.99 a week, kit cook 30 minutes a meal, grocery cook 45 minutes a meal, shopping 60 minutes a week, time value $0 an hour — the kit costs 6 × $9.99 + $9.99 = $69.93 a week, and groceries cost 6 × $4.50 = $27.00 a week, so groceries win by $69.93 − $27.00 = $42.93 a week. Over a year that is $69.93 × 52 = $3,636.36 for the kit against $27.00 × 52 = $1,404.00 for groceries, a saving of $2,232.36 a year, and over 5 years the kit costs $18,181.80 against $7,020.00, a saving of $11,161.80. The kit really costs $9.99 + $9.99 ÷ 6 = $11.66 a serving once shipping is counted, against $4.50 for groceries. The kit takes 6 × 30 = 180 minutes a week, and groceries take 6 × 45 + 60 = 330 minutes a week, so the kit saves 330 − 180 = 150 minutes a week, which is 2.50 hours.

The worked example, line by line
Setup: 6 servings a week, kit $9.99 a serving, groceries $4.50 a serving, shipping $9.99 a week, kit cook 30 minutes a meal, grocery cook 45 minutes a meal, shopping 60 minutes a week, time value $0 an hour.
Line 1 — the kit per week. 6 × $9.99 + $9.99 = $59.94 + $9.99 = $69.93 a week.
Line 2 — the groceries per week. 6 × $4.50 = $27.00 a week.
Line 3 — the weekly winner. $69.93 − $27.00 = $42.93 a week to the groceries.
Line 4 — the year and the 5 years. Kit $69.93 × 52 = $3,636.36 a year, groceries $27.00 × 52 = $1,404.00 a year, so groceries save $2,232.36 a year; over 5 years the kit costs $18,181.80 against $7,020.00, a saving of $11,161.80.
Line 5 — the true cost per serving. The kit really costs $9.99 + $9.99 ÷ 6 = $11.66 a serving once shipping is counted, against $4.50 for groceries.
Line 6 — the time. The kit takes 6 × 30 = 180 minutes a week, and groceries take 6 × 45 + 60 = 330 minutes a week, so the kit saves 330 − 180 = 150 minutes a week, which is 2.50 hours. At $25 an hour that time is worth 2.50 × $25 = $62.50 a week, which is more than the $42.93 the kit costs extra, so the kit wins by $62.50 − $42.93 = $19.57 a week once time is valued, or $1,017.64 a year.
Every branch, checked
3 servings a week: the kit costs 3 × $9.99 + $9.99 = $39.96 a week, and groceries cost 3 × $4.50 = $13.50 a week, so groceries win by $26.46 a week, which is $1,375.92 a year. Fewer servings make the kit worse per serving, because the $9.99 shipping is spread across only 3 servings, so the true kit price is $9.99 + $9.99 ÷ 3 = $13.32 a serving.
12 servings a week: the kit costs 12 × $9.99 + $9.99 = $129.87 a week, and groceries cost 12 × $4.50 = $54.00 a week, so groceries win by $75.87 a week, which is $3,945.24 a year. More servings spread the shipping thinner, so the true kit price falls to $9.99 + $9.99 ÷ 12 = $10.82 a serving, but the $5.49 a serving gap on the food itself is still bigger than the shipping saving.
Kit price $7.99 (intro offer): the kit costs 6 × $7.99 + $9.99 = $57.93 a week, while groceries stay $27.00 a week, so groceries win by $30.93 a week, which is $1,608.36 a year. A $2.00 intro discount saves $12.00 a week, but the kit is still more than twice the grocery cost, because the shipping alone is nearly $10.00 a week.
Groceries $6.00 a serving: groceries cost 6 × $6.00 = $36.00 a week, while the kit stays $69.93 a week, so groceries win by $33.93 a week, which is $1,764.36 a year. Even pricier groceries — better cuts, organic produce, a fancier recipe — still come in well under the kit, because the kit price plus shipping is $11.66 a serving.
Free shipping: the kit costs 6 × $9.99 = $59.94 a week, while groceries stay $27.00 a week, so groceries win by $32.94 a week, which is $1,712.88 a year. Free shipping saves $9.99 a week, but it does not close the gap: the kit price alone is $9.99 a serving against $4.50 for groceries, which is $32.94 a week on its own.
Flip — time value $25 an hour: the kit saves 150 minutes a week, which is 2.50 hours, and 2.50 × $25 = $62.50 a week of time, which is more than the $42.93 a week the kit costs extra, so the kit wins by $62.50 − $42.93 = $19.57 a week once time is valued, or $1,017.64 a year. Time is the only thing that flips this comparison: the kit has to save enough hours, at a high enough hourly value, to cover the money gap.
10-year horizon: the kit costs $3,636.36 × 10 = $36,363.60, and groceries cost $1,404.00 × 10 = $14,040.00, so groceries save $22,323.60 over 10 years. A longer horizon grows the saving in straight proportion, because neither side has a big one-off cost: it is a weekly gap, repeated 520 times.
Reverse — the break-evens: the kit price breaks even at $2.84 a serving, because the groceries cost $4.50 a serving and the shipping adds $9.99 ÷ 6 = $1.67 a serving, so $4.50 − $1.67 = $2.84 (exactly $2.835). The grocery cost breaks even at $11.66 a serving, because the kit really costs $9.99 + $1.67 = $11.66 a serving. The time value breaks even at $17.17 an hour: $42.93 ÷ 2.50 hours = $17.17 an hour. And groceries save $1,000 a year at just 2 servings a week, because 2 servings save 52 × (2 × $5.49 + $9.99) = $1,090.44 a year, while 1 serving saves only $804.96 a year.
What the defaults assume
The model assumes both sides make the same meals, so the price per serving is the only money difference, and it assumes prices stay flat for the whole horizon, with no price rises or intro offers that expire. It assumes the kit cook time and the grocery cook time are for the same recipe, and it counts the shopping trip once a week, not the small top-up shops in between. It assumes the time value is the same every week, and it leaves out food waste, the variety of the menu, the cost of pantry staples you already own, the delivery tip, and the subscription discounts that come and go, which are real but not priced here. Rounding convention: money is rounded to cents, time to 2 decimals, and all figures are computed from unrounded values, rounded only for display.

Who uses this
- The single professional who eats at home most nights: they learn groceries cost $27.00 a week against $69.93 for the kit — so they know the kit costs $42.93 a week extra, and they check the $25-an-hour flip at $19.57 a week before they subscribe.
- The parent feeding a family of four: they learn 12 servings a week cost $54.00 in groceries against $129.87 for the kit — so they know the kit costs $75.87 a week extra, and they check the free-shipping case at $59.94 a week before they order a box.
- The new cook who hates meal planning: they learn the kit saves 150 minutes a week, worth $62.50 at $25 an hour — so they know the time is worth more than the $42.93 it costs, and they check the $17.17-an-hour break-even before they decide what their evenings are worth.
- The budgeter tracking the grocery bill: they learn groceries save $2,232.36 a year at 6 servings a week, and $1,000 a year at just 2 servings a week — so they know the kit is a convenience buy, not a saving, and they check the $7.99 intro offer at $57.93 a week before they try one box.
Accuracy & limitations
The math is exact for the numbers you enter: the kit is the servings times the kit price plus the shipping, the groceries are the servings times the grocery cost, the annual cost is the weekly cost times 52, the effective kit price is the kit price plus the shipping divided by the servings, and the time saved is the grocery time minus the kit time. What the model cannot do is price your shop for you: check the grocery cost per serving from your own receipts, because a $4.50 dinner and a $6.00 dinner give very different answers. It assumes the same meals on both sides, flat prices, one weekly shop, and a steady time value, and it leaves out food waste, menu variety, pantry staples you already own, delivery tips, and subscription discounts that come and go.
