How It Works
This calculator works in 4 steps.
Enter price and size
Type the concentrate price and container volume.
Enter the dilution ratio
Type the label ratio and its convention.
Enter the use container
Type the bottle or bucket volume for cost per fill.
Read the results
The calculator returns cost per RTU gallon and liter, cost per fill, and RTU yield.
The Formula
The formula divides the concentrate unit price by the total ratio parts.
p = price / V_containerc = p / (X + 1)Y = V_container × (X + 1)- p:
- Price per unit of concentrate
- X:
- Water parts per concentrate part
- Y:
- Ready-to-use yield
A $40 gallon of concentrate at 1:64 costs $40 / 65 = $0.615 per RTU gallon and yields 65 gallons of RTU solution.
Conversion Table
The conversion table gives cost per ready-to-use gallon and liter and the yield for 6 products.
| Concentrate | Ratio | Cost per RTU gal | Cost per RTU L | RTU yield |
|---|---|---|---|---|
| $40 / 1 gal | 1:64 | $0.615 | $0.1626 | 65 gal |
| $40 / 1 gal | 1:128 | $0.310 | $0.0819 | 129 gal |
| $25 / 1 gal | 1:32 | $0.758 | $0.2001 | 33 gal |
| $120 / 5 gal | 1:256 | $0.093 | $0.0247 | 1,285 gal |
| $18 / 0.25 gal | 1:10 | $6.545 | $1.7291 | 2.75 gal |
| $60 / 2.5 gal | 1:100 | $0.238 | $0.0628 | 252.5 gal |

What Is the Dilution Cost Calculator?
The Dilution Cost Calculator is a tool that returns the concentrate cost per unit of prepared solution, such as cost per gallon or per liter of ready-to-use (RTU) mix. The cost equals the concentrate price per unit divided by the total parts of the dilution ratio.
Concentrates with different prices and ratios are hard to compare by bottle price alone. A $40 gallon at 1:128 costs less per use than a $25 gallon at 1:32. The calculator returns cost per RTU gallon, per liter, and per container fill, plus the RTU yield of one concentrate container.
