Cat Litter Cost Calculator
Calculate the true cost of cat litter for your household. Compare different products to see monthly, annual, and 5-year expenses.
The number that moves most in this calculator is how often you empty the whole box, and most people empty it because it has started to smell rather than because the litter is used up. Purrify has a piece on how often a box actually needs changing that is worth reading before you set the slider.

Calculation Methodology
Odor add-on: the add-on tick box adds a flat $24 a month. Carbon additives
are not all priced the same and prices move, so check the current one on
purrify.ca
before you trust the total. Purrify shares an owner with this site and that link is commercial.
Usage Estimate: Based on average cat waste production (0.5 lbs/day) and typical litter-to-waste ratio (3:1).
Calculations adjust for full box changes and household size. Your actual usage may vary based on litter box type,
scooping frequency, and individual cat behavior. Addon costs reflect typical monthly usage rates.
