How much does custom formulation cost compared to private label?

Private-label typically requires little or no formulation fee — costs are absorbed in the per-unit price. Custom formulation fees range from roughly $1,500 for a simple candle or basic cleaner blend to $15,000 or more for complex cosmetic actives, supplement stacks, or EPA-registered agricultural products. You also need to budget for stability testing, regulatory review, and iteration rounds before production.
