Raw Material Cost Calculator
Per-unit formulation cost from ingredient prices and usage.
About this calculator
This calculator turns formula percentages and bulk ingredient prices into per-unit cost of goods for a cosmetic SKU. Each phase weight is batch size times that phase's percentage divided by one hundred (lines 33-38). Phase cost converts grams to kilograms and multiplies by the phase price per kilogram for water, oil, actives, emulsifier, preservative, and fragrance (lines 45-50). Batch Raw Material Cost sums those six phase costs (line 52). Unaccounted Formula Percent is one hundred minus the sum of entered phase percentages (lines 41-42). Units Per Batch divides batch size by fill weight per unit, with rounding that prevents floating-point noise from dropping a unit (line 58).
Raw Material Cost Per Unit divides batch raw material cost by units per batch (line 61). Total Cost Per Unit adds packaging and labeling costs per unit to raw material cost per unit (line 62). Suggested Retail Price multiplies total cost per unit by target markup (line 65). Gross Margin Percent derives from retail price minus total cost divided by retail price (lines 66-68). Actives Cost Share is actives cost as a percentage of total raw material cost (line 82).

How to Use This Calculator
- Enter the usage percentage and cost per kilogram for each formula phase (water, oil, actives, emulsifier, preservative, fragrance).
- Set the target batch size in grams.
- Review the raw material cost breakdown and total batch cost.
- Divide total batch cost by yield units to calculate cost of goods (COGS) per unit.
- Adjust individual usage levels or source alternatives to meet your COGS target.

How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersBatch size (g) = 5000, Fill weight per unit (g) = 50, Water phase (%) = 65, Water phase cost ($/kg) = 2 = 17 input(s) provided
- Calculate Total cost per unitTotal cost per unit = rawCostPerUnit + packagingCostPerUnit + labelingCostPerUnit2.71 = $2.71
- Calculate Suggested retail priceSuggested retail price = totalCostPerUnit * targetMarkup10.84 = $10.84
- Calculate Gross marginGross margin = suggestedRetailPrice > 075 = 75

Frequently Asked Questions
Why does Packaging Cost Per Unit move Total Cost Per Unit when batch size stays the same?
Total Cost Per Unit equals raw material cost per unit plus packaging cost per unit plus labeling cost per unit (line 62). Packaging and labeling are flat per finished unit, not spread across batch weight, so each dollar added to container cost flows one-for-one into total cost per unit regardless of how many grams you manufacture.
How does the calculator avoid undercounting units when batch size divides evenly?
Units Per Batch rounds the batch-size-over-fill-weight ratio to six decimal places before flooring (line 58). That guards against IEEE floating-point values like 999.999999 when the ratio should be an even thousand, which would otherwise silently reduce yield by one unit and inflate per-unit raw material cost.
What does Unaccounted Formula Percent tell me about my inputs?
The engine sums water, oil, actives, emulsifier, preservative, and fragrance percentages and subtracts from one hundred (lines 41-42). A large positive remainder means part of the formula is not priced in this worksheet — thickeners, chelators, or colorants you omitted will make raw material cost look artificially low.
Does Target Markup change Gross Margin Percent the way you might expect?
Suggested Retail Price is total cost per unit times target markup (line 65). Gross Margin Percent is retail minus total cost divided by retail price (lines 66-68). Because markup multiplies the entire cost stack, higher markup raises both numerator and denominator in the margin formula, producing the fixed relationship implied by a pure multiplier pricing model rather than an independent margin target.
