You also pay staff to order, stock, swap and bag it. This tool counts only the restrooms you'll actually upgrade — so the saving and the investment line up honestly.
The sector just sets a rough starting guess for how busy a toilet is. Your own roll count beats our guess — enter it if you have it.

The headline number is the hard-dollar paper bill you stop paying. The "capacity value" is separate on purpose: freed-up staff minutes only become real cash if hours, overtime or outsourced work actually go down — so we don't add it to the headline. Set handling time to 0 to ignore it.

Assumptions & sources (we show our math)
Scope matches on purpose. Savings are counted only for the toilets you say you'll upgrade — never for the whole building. That keeps the saving and the ~$40-per-toilet investment on the same footing.
The number that matters most is the real annual roll count in exactly those restrooms. "Rolls per toilet per week" is only a rough placeholder — a busy public restroom burns through far more than a quiet office one. Enter your invoice or stock figure and ignore our guess.
Headline = hard dollars. Paper bill saved = rolls avoided × your price per roll. That's money you stop spending.
Capacity value is separate and optional. Handling time (default 1 min/roll, adjustable to 0) valued at your wage. It's freed-up minutes, not automatic cash — it only counts if hours/overtime/outsourcing actually fall. Ordering happens per case or pallet, so treat this as an upper-ish estimate, not a benchmark.
Payback is shown from the hard-dollar paper saving only. If it comes out under a month from our defaults, we flag it — a real sub-month payback needs your actual roll counts, not our placeholder.
Water ≈ 80 L per roll (midpoint of a wide ~23–140 L range) minus the small amount a bidet uses; treat water as the least-certain line. CO₂ ≈ 1.5 kg/roll (life-cycle estimate, virgin fibre).
Paper reduction 60% default — more cautious than the ~75% households report, because people still pat dry. Device ≈ $40 per toilet (non-electric attachment); heated units cost more.
These are planning estimates, not an audit — and a consumer attachment is not a specification for clinical or industrial settings.
