How to calculate skincare cost per ml
Divide the total price you pay by the product volume in millilitres. To get the price per 10 ml, multiply that result by 10. Include delivery fees when comparing products from different stores. Example: a 30 ml serum costing €9 in total is €0.30 per ml or €3.00 per 10 ml.
Compare like with like
A serum and a thick cream are not interchangeable, even if one costs less per ml. Consider the ingredients, formula, purpose, size and tolerance as well as price. If packaging only shows grams, don't treat grams as ml without knowing product density.
What this calculator does not measure
Unit price is not a measure of effectiveness, quality or whether a product is appropriate for your skin. Prices are entered by you rather than retrieved live from retailers. This calculator doesn't recommend medical treatment.
