Compare tallow balm cost per 100 g
Direct answer
Divide the package price by its net weight in grams, then multiply by 100. This normalises package size for a simple price comparison; it does not measure quality, safety, value or skin suitability.
Use the price and net mass for the exact packages you are considering.
Compare the price per 100 g
Enter the price and net mass printed for each package. The figures stay in this page and are not sent or saved.
Limit: price per 100 g does not rate ingredients, certification, quality, safety or suitability. Include delivery in both entered prices if you want to compare delivered totals.
Key takeaways
- Use package prices in pounds sterling.
- Enter net product mass in grams.
- Include delivery in both totals if it applies.
- Compare cost only; do not treat it as a product score.
Why normalise package size?
A small jar and a larger jar cannot be compared by shelf price alone.
The calculator reports the entered price per 100 g. It makes no adjustment for ingredients, certification, packaging, postage or a product’s intended use.

Use the same price basis
Enter the price you would pay and the net mass printed for each package.
If delivery changes the total, include it in both price inputs. Do not enter personal, payment or order information.
What the result does not tell you
A lower cost per 100 g does not establish that a formula is better, safer or suitable for you.
Check claims, ingredients, certification and seller terms separately.
