Two quotes, two packages of different sizes and shipping in the middle: which one is cheaper? The answer only appears when everything is converted to cost per ml. The calculator compares up to three quotes and points out the lowest.
It does not assess quality or provenance, only price. Work only with registered, traceable product. Your data stays in your browser and the starting values are a hypothetical example.
What does each field mean?
| Field | What to enter |
|---|---|
| Package price | The total purchase amount of the quote, in reais. |
| ml in the package | The total volume of the purchase. |
| Shipping | The shipping cost for that quote. Zero if it is free. |
Fill in A and B, and C if you have a third quote. Leave C's price at zero to ignore it.
How is it calculated?
- Cost per ml = (price + shipping) ÷ ml in the package.
- Lowest cost = the quote with the lowest value per ml.
- Difference = cost per ml of A minus that of B. Positive: B is cheaper.
Worked hypothetical example
Hypothetical example: A costs R$ 700.00 for 1 ml, with no shipping. B costs R$ 1,250.00 for 2 ml, with R$ 40.00 shipping.
| Quote | Calculation | Cost per ml |
|---|---|---|
| A | 700 ÷ 1 | R$ 700.00 |
| B | (1,250 + 40) ÷ 2 | R$ 645.00 |
| Difference A minus B | R$ 55.00 |
B comes out R$ 55.00 cheaper per ml. But buying B takes R$ 1,290.00 up front, and if the volume is slow to move, expiry and tied-up capital weigh in. See the cost of idle inventory.
How do I use the result?
Take the cost per ml of the winning quote to the price per ml and margin calculator to see the effect on your price. If you lose part of the product, the effective cost is higher: use the real cost per ml with waste. And match the purchase to your consumption rate with the inventory reorder point.
Frequently asked questions
How do I compare hyaluronic acid supplier prices?
Divide the package price plus shipping by the ml it contains. Cost per ml lets you compare packages of different sizes.
Is the lowest price per ml always the best buy?
No. Also weigh the product registration, origin, traceability, expiry date, storage conditions and support. A low price without provenance is a risk.
Does shipping count toward the cost per ml?
Yes. High shipping on a small order can turn the cheapest quote into the most expensive.
