Is it actually worth it?
Drop in the price and size of any beauty products — skincare, makeup, hair, tan — and see the real cost per ml, per gram and per use. The number the marketing doesn't put on the front.
Enter at least one product and hit “Calculate value”.
Tip: leave “uses” blank to compare on price-per-ml; fill it in (e.g. 60 pumps) to compare on true cost-per-use.
How to read it
Price-per-ml is the fairest way to compare two products of different sizes — a bigger bottle that looks dear up front is often the cheaper buy. Cost-per-use is the more honest number for anything you dispense in fixed amounts (a pump of serum, one sheet mask, a pea of retinol).
Neither number tells you whether a formula is good — that's what our reviews are for. But together they tell you fast whether you're paying for the product or for the packaging and the ad budget.
Questions
- How do you calculate price per ml?
- Divide the price by the size. A 200ml lotion at AU$48 is $0.24 per ml. Same maths for per-gram with grams.
- What's a “good” price per ml?
- It's relative to the category — body lotion is cents per ml, a serious active serum can be $1–3. Compare like-for-like, not across categories.
- When is cost-per-use better than price-per-ml?
- When the dose is fixed: serums, eye creams, masks, treatments. A “small expensive” product can win on cost-per-use if a little goes a long way.
