A cost-per-milligram worksheet can make a liquid-format comparison clearer, but only when you use matching label information. It is a math tool, not a measure of quality and not a recommendation about use. The goal is simple: compare current product information on the same stated basis.
Before you calculate anything, open each live product page and write down the current listed price. Then read the full label statement connected to the milligram amount. You need to know whether that amount is stated per serving or per container. Do not divide or compare numbers from different bases.
Start with a blank worksheet
| Field | Product A | Product B |
|---|---|---|
| Product name | ||
| Current listed price | ||
| Label basis, per serving or per container | ||
| Milligram amount on that same basis | ||
| Servings per container | ||
| Batch number | ||
| Available lab report reference | ||
| Cost per matching milligram basis |
Leave a field blank if the label does not disclose the information required. A blank is more accurate than a made-up conversion. The worksheet becomes useful when both columns use the same unit and the same label basis.
The core formula
When the current listed price and the matching label amount are both available, use:
Current listed price ÷ milligrams on the same stated basis = cost per milligram
For example, if Product A lists a milligram amount per container, the price in the numerator must be the current price for that same container. If Product B lists a milligram amount per serving, first determine whether its label gives the exact information needed to create a per-container figure. If it does not, compare both products per serving instead, or do not make the comparison.
Use a second formula only when the label supports it
If a label clearly states both a milligram amount per serving and the number of servings per container, you can calculate the labeled container total:
Milligrams per serving × label servings per container = labeled milligrams per container
Then use the core formula with the current listed container price. Keep the calculation labeled as a container calculation. Do not blend a per-serving result from one product with a per-container result from another.
Review available reports before relying on the worksheet
Price math does not verify a product record. The Lab Tests page lists available reports. Record the report date and any lot or sample identifier. Only call it a package match when both the report and package show the same identifier.

Compare portable formats fairly
Liquid products can use different container sizes, serving statements, and label layouts. The correct response is not to pick the largest number. It is to preserve each label's basis, write down the current price, and compare only numbers that refer to the same unit. Use How to Compare Kratom Shot Labels and Servings for the full label checklist.
If you are deciding between a liquid product and a larger-format option, use separate comparison rows until you have a consistent basis. How to Compare Bulk Kratom Value explains how to work from package size, label servings, current price, and batch documentation without forcing unlike formats into one number.
Finish with the comparison page
The comparison page can help you line up product details before you fill in the worksheet. Return to the live listing for the current price every time you rerun the calculation. Prices, available configurations, and batches can change, so a saved worksheet is a snapshot, not a permanent product record.
The strongest result is the simplest one: current price divided by a clearly matched label amount, with any available report used only for what it actually discloses.
