Cleaning solution dilution calculator

Enter the volume of working solution you need and the dilution ratio from the product label, in 1:N form (one part concentrate to N parts water). The calculator works out how much concentrate and water to use.

The N from the product label, e.g. 200 for a 1:200 ratio
Leave blank if you don't need the solution's cost

How it is calculated

At a 1:N ratio the whole solution splits into N+1 parts, one of which is concentrate. Concentrate = volume needed ÷ (N + 1); water is the remainder up to the volume needed.

The label's dilution rate is set by the manufacturer for the active ingredient's concentration — under-dosing cuts effectiveness, over-dosing just wastes chemical and leaves residue on surfaces.

Solution cost = concentrate volume × concentrate price per liter. Cost per liter of working solution = cost ÷ volume needed — handy for comparing different products on a per-liter-of-ready-solution basis.
