Cost calculator
Price per serving
See what one serving costs from the price of the container and the servings on the label.
This is a cost calculation. It does not judge product quality or suitability.
Questions
Is the 30-day figure a calendar month?
No. Daily use is 30 servings, every-other-day use is 15, and weekly use is 30/7.
Does a lower cost mean a better supplement?
No. The page only divides the presented price by the servings you enter.
Where do the servings come from?
You type them. They are not read from a label image or from Baseline.
How this number is made
What this result means
The result is what the presented price works out to for one serving, and the estimated cost of using it for 30 days at the schedule you chose. That 30-day figure is not the price of buying the next bottle, and it is not a calendar month.
Formula and methodology
Cost per serving is the price divided by the servings you enter. A 30-day estimate uses that full-precision cost. Daily is one serving times 30. Every other day is half a serving times 30. Weekly is one serving times 30/7. A custom count uses the same daily or weekly rate. Rounding to the cent happens once, for display.
Worked example
A container priced at 30 with 60 servings costs 0.50 per serving. Used daily, 30 days costs 15.00 and the container lasts 60 days. Used weekly, 30 days costs 2.14.
Assumptions and limitations
Servings are the number you type from the label. A capsule count is not a serving count. Tax, shipping, coupons, subscriptions, and conditional promotions are outside the figure unless they are already in the price. The currency is the currency of the price. Amounts are not converted.
Who should not rely on the result
Anyone who needs a quote from the retailer, or who wants this number to decide whether a supplement is appropriate, should not treat the result as that decision.
