Cleaning Concentrate Dilution Calculator
Mix a measured bottle from a manufacturer-approved product-to-water ratio. See concentrate, water and estimated cost before you pour.
Plan a bottle fill
Mixing quantities
Only use a dilution approved on the product label. This is volume arithmetic, not chemical safety guidance. Never mix different cleaning chemicals; follow PPE, contact-time and SDS instructions. Product:water ratio is different from product:total-solution ratio.
How product-to-water ratios work
A 1:10 ratio in this calculator means one part product for every ten parts water, for eleven total parts. To fill a 32 US fl oz bottle, concentrate is 32 ÷ 11 = 2.91 fl oz and water is 29.09 fl oz. Some product labels use different conventions; read the actual manufacturer instructions before entering values.
Enter the bottle capacity in US fluid ounces or milliliters. You can optionally enter the price of a gallon of concentrate to estimate the cost of each fill. This is useful when comparing ready-to-use bottles against concentrates, but it cannot decide which strength is effective or safe for a surface.
