THE NUMBERS, EXPLAINED
How to use this calculator.
Procurement arithmetic using already approved product-specific label doses. Does not recommend dilution, mixing products or application.
Start with your inputs
Enter approved finished-solution quantities by job (l), product label doses by job (ml/l), usable concentrate stock (ml), concentrate bottle size (ml). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Approved finished-solution quantities by job (L) | 10,20 |
| Product label doses by job (mL/L) | 5,10 |
| Usable concentrate stock (mL) | 100 |
| Concentrate bottle size (mL) | 500 |
A worked example
With the example inputs above, concentrate required by job (ml) is 50, 200. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Concentrate required by job (mL) | 50, 200 |
| Total concentrate required (mL) | 250 |
| Bottles to purchase | 1 |
How this is calculated
Concentrate required by job (mL)
Apply the supplied label dose to each finished-solution quantity.
Total concentrate required (mL)
Add job product requirements.
Bottles to purchase
Deduct stock and round concentrate shortage to bottles.
Symbols and units
- a
- Approved finished-solution quantities by job (L)
- b
- Product label doses by job (mL/L)
- c
- Usable concentrate stock (mL)
- d

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Procurement arithmetic using already approved product-specific label doses. Does not recommend dilution, mixing products or application.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Concentrate required by job (mL); Total concentrate required (mL); Bottles to purchase. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Procurement arithmetic using already approved product-specific label doses. Does not recommend dilution, mixing products or application.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
