Recipe Scaling Calculator
Scale an ingredient amount from an original yield to a new target yield.
New Amount = Original Amount x (Target Yield / Original Yield)

Best starting point
Recipe Scaling Calculator
Use this hub when a recipe needs to scale up, scale down, or be checked against realistic production yield.
Best for
- Scaling ingredient quantities for a new portion target.
- Thinking through yield loss, batch size, and production limits.
- Connecting recipe scaling with costing and catering production.
Common questions
- What is the scaling factor for this batch?
- Which ingredients should not be scaled blindly?
- Will the larger batch still fit equipment and workflow?
Yield workflow
Recipe scaling and yield workflow
Recipe scaling should start with the math, then move into production checks. A scaled recipe can be correct on paper and still fail if equipment, cook time, cooling, or seasoning do not scale cleanly.
- Confirm the original yield and the target yield.
- Divide target yield by original yield to get the scaling factor.
- Multiply base ingredients by the scaling factor.
- Convert units before scaling when invoice units and recipe units do not match.
- Review ingredient caveats, pan size, cook time, holding, and cooling before production.
Scaling factor
Common scaling factors
| Original yield | Target yield | Scale factor | Production meaning |
|---|---|---|---|
| 10 portions | 50 portions | 5.0x | Make five times the original ingredient amounts |
| 12 portions | 30 portions | 2.5x | Make two and a half times the recipe |
| 40 portions | 20 portions | 0.5x | Cut the recipe in half |
| 24 portions | 36 portions | 1.5x | Increase the recipe by 50% |
Kitchen caveats
Ingredients and steps that need judgment
| Item | Why it may not scale cleanly | Practical check |
|---|---|---|
| Seasoning | Salt, spice, heat, and acid can become too strong in large batches | Start slightly low, taste, then adjust |
| Leavening | Baking chemistry can change with batch size and pan depth | Use tested bakery formulas |
| Thickening | Roux, starch, and reductions depend on heat and time | Scale, cook, then adjust texture |
| Cook time | Heat transfer changes with volume and pan depth | Cook to temperature, texture, and doneness |
| Pan size | Crowding affects browning, evaporation, and cooling | Split into smaller pans or batches if needed |
Practical example
Scaling 10 portions to 50 portions
A sauce recipe that makes 10 portions needs to serve 50 guests. The scaling factor is 50 / 10, or 5.0x. Base ingredients can start at five times the original amount, but salt, chile, thickener, cook time, and pan depth should be checked before service.
| Ingredient | Original amount | Scale factor | Scaled amount | Note |
|---|---|---|---|---|
| Tomato base | 2 qt | 5.0x | 10 qt | Scales directly |
| Stock | 1 qt | 5.0x | 5 qt | Hold some back for texture |
| Salt | 1 tbsp | 5.0x | 5 tbsp | Start lower and taste |
| Chile flakes | 1 tsp | 5.0x | 5 tsp | Add gradually |
