Step-by-step
- Multiplier = target / original = 6 / 4 = 1.500.
- Apply to sample: 2 × 1.500 = 3.000.
- Apply the same multiplier to every ingredient — flour, sugar, butter, salt, eggs, etc.
How to use this calculator

About this calculator
Scaling a recipe is just multiplying every ingredient by the ratio of target servings over original servings. Most home recipes scale linearly except for very small components (yeast, baking powder, salt) where doubling can produce off-flavor. For 4×+ scale-ups, reduce leavening by 10-20%.
Frequently asked
Most things do — flour, sugar, butter, milk, oil, etc. Salt, baking soda/powder, yeast, and strong spices may need adjusting if you scale up 3×+ to avoid bitterness.
