- Cost per gram = price ÷ net weight (g)
- Cost per serving = cost per gram × serving size (g)
- Cost per 30 days = cost per serving × servings per day × 30
How to work it out
- Find the net weightOn the label, in grams. Ignore the jar or box weight.
- Find the serving sizeIn grams or milligrams on the label (1,000 mg = 1 g).
- Add delivery if you pay itInclude it in the price for a true cost, or compare without it if delivery varies.
- Divide, then multiplyPrice ÷ grams gives cost per gram; × serving gives cost per serving.

Each cell shows cost per serving / cost for 30 days. Use the serving size on your product’s label.
Capsules, gummies and powders
For anything sold by count, work from the shilajit content, not the pack weight or the blend weight.
A pack of 60 capsules costs £24 and each capsule contains 250 mg of shilajit extract. Total shilajit = 60 × 250 mg = 15,000 mg = 15 g. Cost per gram of shilajit = £24 ÷ 15 = £1.60. At two capsules a day, cost per day = 2 × (£24 ÷ 60) = £0.80, or £24.00 for 30 days.
If a label only gives a “blend” weight with no shilajit figure, you can’t calculate cost per gram of shilajit at all. That is a transparency problem in itself; see shilajit forms and how to read a label.
What cost per gram doesn’t tell you
- QualityA cheaper gram is not a better gram. Check the batch COA first; see laboratory testing.
- Different materialsA standardised extract and a whole resin aren’t the same material; see extract vs resin.
- WasteResin that sticks to the scoop or jar adds to the real cost per serving.
- BundlesMulti-buys only save money if you’ll use the stock before its date mark; see subscriptions and multi-buys.

Common questions
What is a fair price per gram for shilajit?
Prices vary with format, documentation and pack size. Compare products with similar testing and format on cost per serving, rather than chasing the lowest figure. See shilajit prices in the UK.
Should I include delivery?
Yes, if you’re comparing what you’ll actually pay. Add the delivery charge to the price before dividing by the net weight.
Is a bigger jar always cheaper per gram?
Usually, but not always. Run the numbers for each size; the ready-reckoner makes the comparison quick.
