Bulk supplement packages: find the usable-serving break-even point
Compare bulk and small packages using expected usable servings, cash required today and a transparent break-even calculation.
Turn a bottle price and serving size into a comparable unit cost and supply estimate.
Enter the price of one bottle and its allocated checkout charges. Discounts are dollar amounts, not percentages. Read the package for total capsule, tablet or gummy count and the number of those units in one labeled serving. The daily-use input is a budgeting assumption you supply, not a dose recommendation.
Formula: net bottle cost = price + charges − discount; servings = units ÷ units per serving; cost per serving = net cost ÷ servings. Supply days = servings ÷ assumed daily servings. Thirty-day consumption cost = cost per serving × daily servings × 30.
Illustrative example: a $24 bottle with $4 charges and 120 capsules at two capsules per serving contains 60 servings. Its $28 net cost divided by 60 is $0.4667 per serving. At one serving a day, supply is 60 days and the 30-day consumption cost is $14. This is allocated consumption cost, not necessarily the cash paid this month.
The calculator cannot assess safety, absorption, effectiveness, expiry or whether two products are medically interchangeable. Compare matching labeled quantities first. Fractional counts are allowed for powders measured by weight, but use consistent units. Zero denominators and discounts larger than the checkout cost are rejected. Calculations stay in your browser.

Do the math
Use a repeatable price worksheet that separates label quantities, checkout costs and assumptions without inventing a product ranking.
Do the math
Translate percentage and dollar offers into comparable checkout costs while keeping eligibility, minimum spend and future rewards separate.
Do the math
Plan a supplement budget with inventory and whole-package purchases instead of confusing a 30-day cost estimate with the bill due today.
Read the label
Build a useful supplement comparison by recording serving size, ingredient amounts, other ingredients and the exact package identity.
Read the label
Distinguish capsule count, labeled servings and days of supply so that package-size comparisons use the same denominator.
