What a Self-Cleaning Litter Box Really Costs — Cost of Ownership Calculator
Six inputs. The three-year bill, both ways.
The sticker price is the smallest honest number in this category. A $229.99 box that eats a proprietary tray every month costs more over three years than a $499.99 globe that runs on the litter you already buy — and a second cat rewrites both columns. Tell this calculator your box price, your cat count, and your litter and consumable costs, and it returns year-1 and 3-year totals for the automatic box versus scooping a manual box, with the reasoning shown. Defaults are pre-filled from CatboxLab’s November 11, 2026 research file — change any of them to your real numbers.
Your result appears here. Defaults model a $499.99 globe, one cat, and about $6/month in liners and filters — press Calculate, then try the tray preset below and watch the ranking flip.
Presets from the research file (Nov 11, 2026): Litter-Robot 5 — $799 box, ~$6/mo consumables. Litter-Robot 4 — $699, ~$6/mo. PETKIT Purobot Max Pro 2 — $499.99, bags/filters (verify current consumable prices). Neakasa M1 — $379.99, any-bag consumables, lowest lock-in. PetSafe ScoopFree Crystal Pro — $229.99 box, ~$24.50/mo in disposable trays at one tray per month for one cat, and set auto-box litter to 0 — the tray includes its crystal litter. Preset values are starting points from manufacturer-store research, not quotes.
Matched picks for the two shapes of answer
LOWEST LOCK-IN
The globe that takes any bag
The Neakasa M1 ($379.99 at neakasa.com, checked November 11, 2026) is the cost-calculator’s friend: open-top, any fitting waste bag, standard clumping litter, and the largest bin here at 11.23L. When the calculator’s consumables line is the thing scaring you, this is the shape of box that fixes it.

THE TRAY MATH, HONESTLY
Cheapest in, priciest to run
The PetSafe ScoopFree Crystal Pro ($229.99 at petsafe.com, checked November 11, 2026) wins year 1 for one cat and loses year 3 to almost everything — the calculator shows the crossover with your own tray price. If your result still favors it (one cat, small space, no app wanted), it is a legitimate buy with open eyes.

How the calculator works
A manual box costs litter and nothing else — which is exactly why its column looks unbeatable until you price your time honestly. This calculator deliberately leaves time out of the dollar math and shows it separately: scooping twice a day at two minutes is roughly 24 hours a year. What it does count, it counts plainly. The automatic column is the box price once, plus (auto litter + consumables) every month. Litter scales with cats in both columns: the per-month litter figures you enter are multiplied by your cat count, because a two-cat household does not use one cat’s litter in either box. Automatic boxes usually use less litter per month than a manual box — waste leaves after every visit instead of contaminating the bed — so the defaults assume 14 lb against 20 lb; if your current bag-a-month habit says otherwise, type your real numbers.
| Line | Auto box | Manual box |
|---|---|---|
| Up front | Box price | $0 |
| Monthly litter | Auto lb × $/lb × cats | Manual lb × $/lb × cats |
| Monthly consumables | Your $/mo (scales with cats) | None |
| Year 1 | Box + 12 × monthly | 12 × monthly |
| 3 years | Box + 36 × monthly | 36 × monthly |
Consumables are where the models diverge, so the defaults carry their sources: globe liners and filters run in the low single digits per month when any-bag systems are used; Whisker’s own liners/filters price higher (re-verify on whisker.com at publish). A ScoopFree crystal tray at ~$24.50 (3-pack $73.49 at major pet retailers, checked November 11, 2026) is both litter and consumable in one — model it with auto litter at 0 lb and consumables at $24.50 times your cat count’s tray pace. Electricity is excluded: every box here draws a few watts intermittently, well under a dollar a month at residential rates, and it does not move the ranking. These are planning numbers built from the same research file as our flagship comparison — hold any retailer’s “cost per day” claim up against them.
