THE NUMBERS, EXPLAINED
How to use this calculator.
Mass-ratio inventory arithmetic only. Use compatible products and manufacturer-prescribed ratios; the tool does not recommend a formulation.
Start with your inputs
Enter required mixture batch mass (g), manufacturer product a ratio parts, manufacturer product b ratio parts, available product a (g), available product b (g). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Required mixture batch mass (g) | 120 |
| Manufacturer product A ratio parts | 1 |
| Manufacturer product B ratio parts | 2 |
| Available product A (g) | 50 |
| Available product B (g) | 70 |
A worked example
With the example inputs above, product a required (g) is 40. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Product A required (g) | 40 |
| Product B required (g) | 80 |
| Product A shortage (g) | 0 |
| Product B shortage (g) | 10 |
How this is calculated
Product A required (g)
Allocate batch mass by the supplied part ratio.
Product B required (g)
Allocate the remaining mass using product B ratio.
Product A shortage (g)
Compare the required amount with available stock.
Product B shortage (g)
Compare product B requirement with available stock.

Assumptions and limits
Mass-ratio inventory arithmetic only. Use compatible products and manufacturer-prescribed ratios; the tool does not recommend a formulation.
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?
Product A required (g); Product B required (g); Product A shortage (g); Product B shortage (g). 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: Mass-ratio inventory arithmetic only. Use compatible products and manufacturer-prescribed ratios; the tool does not recommend a formulation.
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.
