60 label servings × 600 mg = 36 g EPA + DHA in the bottle.
1,000 mg is a price comparison unit, not a suggested dose. Use EPA and DHA, rather than total fish oil. No currency conversion.
How it works
Count the EPA + DHA.
Compare the same amount.
A bottle’s fish oil weight and its EPA + DHA content are different quantities. NIH’s omega-3 fact sheet explains that formulations vary widely, so check the individual amounts on the label. This tool uses those declared amounts without estimating absorption.
Find these five numbers
Use the price and softgel count for the same bottle size. On the Supplement Facts panel, find the serving size in softgels, then the EPA and DHA amounts for that whole serving. If the label lists two softgels per serving, those milligrams apply to two, rather than one.
Label servings = softgels in bottle ÷ softgels per serving
EPA + DHA in bottle (g) = label servings × (EPA mg + DHA mg) ÷ 1,000
Cost per 1,000 mg EPA + DHA = bottle price ÷ EPA + DHA grams in bottle
The cheaper bottle can cost more
Here is an illustrative two-bottle comparison. Both have 120 softgels and a two-softgel label serving, giving 60 servings each.
| Bottle numbers | A | B |
|---|---|---|
| Price | $24 | $20 |
| EPA / label serving | 360 mg | 180 mg |
| DHA / label serving | 240 mg | 120 mg |
| EPA + DHA / bottle | 36 g | 18 g |
| Cost / 1,000 mg EPA + DHA | $0.67 | $1.11 |
Bottle A has a higher sticker price, but costs less for the same declared EPA + DHA amount. This does not establish which product is better overall or how much anyone should take.
What if the EPA or DHA amount is missing?
Leave it blank. A missing amount is unknown, rather than zero. The calculator needs both amounts, including a known zero for a product that contains only one. Other omega-3 fatty acids, including ALA, are outside this comparison.

Questions
Fish oil price questions.
How do I calculate fish oil cost per 1,000 mg EPA + DHA?
Divide the softgel count by softgels per label serving. Multiply those servings by the EPA plus DHA milligrams per serving, then divide by 1,000 to get grams in the bottle. Divide the bottle price by those grams. One gram equals 1,000 mg; it is a comparison unit, not a recommended dose.
Is 1,000 mg fish oil the same as 1,000 mg omega-3?
No. The fish oil weight includes more than EPA and DHA. Read their separate amounts on the Supplement Facts panel. Total omega-3 can also include other fatty acids; this calculator counts only EPA plus DHA.
What if the serving size is two softgels?
Enter two for softgels per serving, and use the EPA and DHA amounts printed for that two-softgel serving. For example, 120 softgels divided by two gives 60 label servings. Do not enter those per-serving amounts as though each softgel contained them.
Does it work for algae oil or DHA-only softgels?
Yes, if EPA and DHA amounts are known for the same label serving. For a DHA-only product with a known zero EPA amount, enter zero for EPA. Leave an undisclosed amount blank rather than assuming it is zero. EPA plus DHA must be greater than zero. This version uses softgel counts, not liquid volumes.
Can I calculate it if the label only lists total omega-3?
Not reliably with this tool. Total omega-3 does not necessarily equal EPA plus DHA. Ask the manufacturer for the separate amounts for that serving size; do not infer them from total oil weight or a generic percentage.
Does the lowest cost mean the best fish oil?
No. This compares declared EPA plus DHA amounts and your prices. It does not test purity, oxidation, absorption, safety or effectiveness, verify bottle contents, or recommend how much to take. Those questions require different evidence.
Are my numbers saved or shared?
The calculation runs in your browser without an account. The tool does not submit or save your prices or label quantities. Reloading restores the clearly marked example. Use the same currency for both bottles; no exchange conversion is performed.
