Home Coleslaw vs Buying: Save $75 a Month, $900 a Year
On the defaults — 20 days at $2.25 made at home versus $6.00 bought — a home coleslaw costs $45.00 against $120.00 bought, so home saves $75.00 a month and $900.00 a year. This is the COLESLAW comparison — the same days-times-price shape as the making-pasta-salad-at-home-vs-buying-pasta-salad page, the making-salsa-at-home-vs-buying-salsa page and the making-egg-salad-at-home-vs-buying-egg-salad page — with the coleslaw prices and the $2.25 break-even worked in full.
What does saving $75.00 a month on coleslaw mean?
It means 20 days at $2.25 made at home cost $45.00, while the same 20 days bought at $6.00 cost $120.00 — a gap of $75.00 a month, $900.00 over a year of the same routine. The bought coleslaw costs more than two and a half times the home coleslaw, so every bought day you swap for a home day keeps $3.75 in your pocket. Even swapping half the month — 10 home days and 10 bought ones — still saves $37.50 a month.

Three things to check before you trust the number
First, price the home coleslaw honestly: the cabbage, carrots, mayonnaise, vinegar, sugar and seasoning, divided by the servings the batch actually makes. A bowl that only half gets eaten before it turns has a home cost far higher than the per-serving label suggests. Second, use the bought price you really pay, delivery and service charges included — a $5.00 tub price that arrives at $6.00 a serving is a $6.00 coleslaw. Third, count only the days you serve coleslaw: a 20-day month means 20 coleslaw days, not 20 calendar days with a skipped weekend and a soup day tucked in.
Worked example
Twenty days, $2.25 at home, $6.00 bought. Home total: 20 × $2.25 = $45.00. Buying total: 20 × $6.00 = $120.00. Saving: $120.00 − $45.00 = $75.00 a month, $900.00 over 12 months. Break-even: $2.25 a day — if the bought coleslaw ever fell to $2.25, the two sides would be exactly even, and below that buying would win. One home day instead of one bought day saves $3.75 on its own.
Every branch, checked
A $3.00 home cost with the same days and buying cost gives home $60.00 against buying $120.00, saving $60.00 a month. A $5.00 buying cost with the same days and home cost gives home $45.00 against buying $100.00, saving $55.00 a month. Fifteen days with the same home and buying costs give home $33.75 against buying $90.00, saving $56.25 a month. Twenty-five days with the same home and buying costs give home $56.25 against buying $150.00, saving $93.75 a month. Each branch changes exactly one input, so the difference from $75.00 isolates that input.
The reverses, worked backwards
The home cost behind $75.00 a month saved is $2.25: at $1.75 the figures are home $35.00 against buying $120.00, saving $85.00 a month, and at $2.75 they are home $55.00 against buying $120.00, saving $65.00 a month. The buying cost behind $75.00 a month saved is $6.00: at $5.00 the figures are home $45.00 against buying $100.00, saving $55.00 a month, and at $7.00 they are home $45.00 against buying $140.00, saving $95.00 a month. The days behind $75.00 a month saved are 20: at 15 days the figures are home $33.75 against buying $90.00, saving $56.25 a month, and at 25 days they are home $56.25 against buying $150.00, saving $93.75 a month.
What the defaults assume
The defaults assume the same routine every month: 20 coleslaw days, a $2.25 home serving and a $6.00 bought serving, with no change in prices or appetite across the year. Real routines vary: a holiday month may hold few coleslaw days and a barbecue month many, so the honest use is to enter the average month, or to run the calculator once per stretch of the year and add the stretches. Zero days is the honest edge: $0.00 home against $0.00 bought, exactly even. Negative inputs are rejected, and a home cost above the bought price flips the verdict — at $7.00 home against $6.00 bought, home costs $20.00 more a month.
Who uses this
A weekday lunch packer checking the habit: the home line prices the bowl, the bought line prices the tub or deli pot, and the gap is the monthly reason to keep shredding. A family cook scaling the batch: the per-serving home cost falls as the bowl grows, and the calculator shows what each ten-cent saving is worth over 20 days. A student on a tight food budget: the break-even price is the shop price at which making it stops paying, so any tub below $2.25 a serving is genuinely cheaper than home. A meal-prep coach comparing sides: the same days-times-price shape prices coleslaw next to salsa, pasta salad and other packed sides on equal terms.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is in the inputs. A home cost that ignores a bowl left uneaten, a bought price that omits delivery charges, or a day count that includes days you never serve coleslaw will each move the answer by exactly the amount of the error, every month. The model does not include shredding time, energy costs, bowls and tubs, or the value of variety — price those separately, and re-check the comparison when shop prices or grocery prices change.

Frequently asked questions
What goes into the home cost per coleslaw?
The cabbage, carrots, mayonnaise, vinegar, sugar and seasoning, divided by the servings the batch actually makes. If a bowl makes ten servings and costs $22.50 in ingredients, the home cost is $2.25 a serving.
What if I only eat coleslaw on weekdays?
Count only those days: about 20 weekdays in a typical month is exactly the default. A month with holidays or travel holds fewer coleslaw days, so enter the real count, not the calendar length.
Does the bought price include delivery?
It should, if you pay it: the bought price is what leaves your pocket for one bought serving. A $5.00 tub price with a $1.00 delivery share is a $6.00 bought coleslaw for this comparison.
When does buying win?
When the bought price falls to the home cost or below: at $2.25 bought against $2.25 home the two sides are exactly even, and below $2.25 buying is cheaper. Above $2.25, home wins by the gap times the days.
Why does one extra day move the saving by $3.75?
Because each extra day adds one home serving and one bought serving, and the gap between them is $6.00 − $2.25 = $3.75. Days scale the saving directly, which is why the day count matters as much as the prices.
Can I use this for a different packed side?
Yes — the shape is days times price on each side, whatever the food is. Change the labels in your head, enter that food's home and bought prices, and the saving, year total and break-even all follow the same method.
