On the defaults — 10 servings at $2.40 a serving — soup cost is $24.00 in all, $28.80 a dozen. This is the soup cost tool: multiply servings by the price for the total, then scale to a dozen for comparison — a pot guessed from the serving price alone tells you nothing until the servings behind it are known.
Put your servings and price in: 10 servings at $2.40 a serving cost $24.00 in all — $28.80 a dozen.
It means ten servings of soup at $2.40 a serving cost twenty-four dollars in all, which is $28.80 a dozen. The servings set how many bowls are ladled, the price sets what each bowl costs, and the dozen is a fixed twelve servings: one more serving adds a full $2.40 without raising the price, and a higher price adds cost to every serving without adding a single extra bowl. The only judgement is the serving itself — a serving is one bowl as priced, and a bowl topped up twice is not two servings unless it is paid for twice.
| Output | Formula | What it means |
|---|---|---|
| Total cost | servings × price a serving | $24.00 — 10 × $2.40. |
| Cost a dozen | total ÷ servings × 12 | $28.80 — $24.00 ÷ 10 × 12. |
First, check the serving count honestly: 10 servings must be bowls actually ladled, not bowls counted twice because a bowl was refilled when it is served as one bowl — a serving counted that was never ladled adds $2.40 of phantom cost. Second, check what the price includes: $2.40 a serving must be the full serving cost, stock, vegetables, and bread included where they apply — an ingredients-only price quoted for a bowl served with bread is a different price, and mixing the two prices breaks the total. Third, check the pot against the week: $24.00 assumes ten servings at the same price, seconds included — a week where some days take seconds needs more servings, so treat it as the ten-serving total, not the seconds-included total.
10 servings, $2.40 a serving. Total: 10 × $2.40 = $24.00. A dozen: $24.00 ÷ 10 × 12 = $28.80. In practice that means a pot for ten costs twenty-four dollars, and the $28.80 a dozen figure is the one to set against a deli price, since a deli bowl above $2.40 costs more than making it at home.
At 14 servings instead of 10, the cost rises to $33.60 — $28.80 a dozen. At $2.00 a serving instead of $2.40, the cost falls to $20.00 — $24.00 a dozen. At 6 servings instead of 10, the cost falls to $14.40 — $28.80 a dozen. At $3.00 a serving instead of $2.40, the cost rises to $30.00 — $36.00 a dozen.
The servings behind $24.00 are 10: at 6 servings the cost is $14.40; at 14 servings it is $33.60. The price behind $24.00 is $2.40: at $2.00 a serving the cost is $20.00; at $3.00 a serving it is $30.00 — the price never touches the serving count, only the price each bowl pays.
The defaults assume 10 servings at $2.40 a serving, every bowl the same size and recipe. They do not assume a second pot, premium ingredients, or a deli markup — a pot with meat and cream on every bowl needs a higher serving price, so treat $24.00 as the plain-pot cost, not the fully-loaded cost.
The arithmetic is exact for the inputs entered; the judgement is the serving count, the price basis, and whether every bowl really costs the same. Real pots vary with bowl size, recipe, and extras — so treat $24.00 as the planning cost for 10 servings at $2.40, and check it against the actual ingredients before budgeting.

$24.00 on the defaults: 10 servings at $2.40 a serving — 10 × $2.40 = $24.00, or $28.80 a dozen.
$2.40 on the defaults; the dozen figure is $28.80 because a dozen is twelve servings, and it changes only when the serving price changes.
Because a dozen is a fixed twelve servings: it lets pots of different sizes compare fairly, since a total alone hides whether the price or the count moved.
Only if it is in the serving price: a plain $2.40 serving with bread on the side needs a higher price per serving.
Raise the servings, not the price: 14 servings at $2.40 cost $33.60, and the dozen figure stays $28.80.
Compare the deli bowl price with $2.40 a serving: a deli bowl above that figure costs more than making it, and a bowl below it does not.
