The model, stated exactly
Paper annual cost = rolls per week × price per roll × 52. Cloth year-one total = towels bought × price per towel + laundry loads per week × cost per load × 52. Cloth year-two-and-beyond annual cost = laundry loads per week × cost per load × 52, because the towels are already bought. The year-one saving = paper annual − cloth year-one total; the year-two saving = paper annual − cloth laundry-only annual. A negative saving means paper wins. Rolls per year = rolls per week × 52. The model prices money only: it does not price the time spent folding towels, the drawer space they take, or the waste avoided, and it assumes towels last at least two years — a stack of bar mops usually lasts far longer than that, which only improves the cloth side.
The worked example, line by line
Setup: 2 rolls a week, $1.25 a roll, 24 cloth towels at $1.50, 1 laundry load a week at $0.85.
Line 1 — rolls per year. 2 × 52 = 104 rolls.
Line 2 — paper annual. 2 × $1.25 × 52 = $130.00 a year.
Line 3 — cloth up front. 24 × $1.50 = $36.00, paid once.
Line 4 — cloth laundry annual. 1 × $0.85 × 52 = $44.20 a year.
Line 5 — cloth year-one total. $36.00 + $44.20 = $80.20.
Line 6 — the saving. $130.00 − $80.20 = $49.80 in year one; $130.00 − $44.20 = $85.80 a year from year two on.
Try these
Light user: 1 roll a week. Paper costs $65.00 a year against cloth's $80.20 year-one total, so paper wins year one by $15.20 — but from year two on, cloth's $44.20 laundry-only cost still beats paper's $65.00 by $20.80 a year. Light users win with cloth too; they just wait a year for it.
Heavy user: 4 rolls a week. Paper costs $260.00 a year against cloth's $80.20 year-one total, so cloth saves $179.80 in year one and $215.80 a year from year two on. Big paper habits are where cloth pays off fastest.
Premium rolls: $2.00 a roll at 2 a week. Paper costs $208.00 a year against cloth's $80.20, so cloth saves $127.80 in year one. The fancier your paper habit, the faster cloth wins.
Two laundry loads a week. Cloth's year-one total rises to $124.40 ($36.00 + 2 × $0.85 × 52), so against paper's $130.00 cloth saves only $5.60 in year one — and from year two on, laundry alone costs $88.40, saving $41.60 a year. If towels force extra loads, keep them in with existing washing or the saving nearly vanishes.
Output · formula · meaning
| Output | Formula | What it means |
| Paper annual | Rolls/week × price/roll × 52 | $130.00 at the defaults — what a year of paper towels really costs. |
| Cloth up front | Towels × price/towel | $36.00 at the defaults — paid once, in year one only. |
| Cloth laundry annual | Loads/week × cost/load × 52 | $44.20 at the defaults — the only cloth cost from year two on. |
| Cloth year-one total | Cloth up front + cloth laundry annual | $80.20 at the defaults — the fair first-year comparison figure. |
| Year-one saving | Paper annual − cloth year-one total | $49.80 at the defaults — positive means cloth wins; negative means paper wins. |
| Year-two saving | Paper annual − cloth laundry annual | $85.80 at the defaults — the ongoing yearly saving once towels are bought. |
| Rolls avoided | Rolls/week × 52 | 104 at the defaults — rolls never bought, used, or thrown away each year. |
Who uses this
- The household going through a roll every few days: enters 2 rolls a week and sees $130.00 a year, which reframes a $1.25 roll as a $130 habit worth fixing once.
- The light user with one roll a week: enters 1 roll a week and learns paper wins year one by $15.20 but cloth wins from year two on — a one-year wait for a permanent saving.
- The premium-brand buyer: enters $2.00 a roll and watches the paper total jump to $208.00, which makes a $36 stack of bar mops look like the bargain it is.
- The laundromat household: enters a several-dollar load price and discovers whether cloth still wins when every load is paid for by the machine, before buying the towels.
Accuracy & limitations
The comparison is exact for the numbers you enter, but it prices money only. It assumes towels last at least two years (most bar mops last far longer) and that the laundry cost you enter is the true extra cost of towel loads — if towels ride along in loads you would run anyway, the honest laundry cost is $0 and cloth wins by the full paper total. It leaves out the time spent folding and putting towels away, the drawer or basket they live in, and the waste avoided (104 rolls a year at the defaults). It also leaves out replacement towels: if you replace the stack every few years, spread that cost across those years rather than counting it every year. Paper towels still have jobs cloth does not — greasy messes, paint, anything you would rather throw away than wash — so most households land on a mix, not a total switch. Error policy: missing, non-numeric, or out-of-range inputs are reported as errors rather than calculated.
