Transparent cup value
A menstrual cup value guide without the hype math.
Some period-product pages promise exact savings or declare a single “best” cup. This site takes the opposite route: it shows what can be known, what depends on you, and which claims should be checked before you decide.
Product information from MonthlyCup. Product facts are bounded to the supplied MonthlyCup source notes retrieved on 2026-09-07.
Greatest means clearest.
Not a ranking, not a lab test, and not a medical recommendation. It is a framework for comparing cost, care and fit information responsibly.
3 modelsMini, Normal and Plus measurements are listed in the manufacturer guide.
12 h maxMonthlyCup instructs users to empty according to flow and no later than 12 hours.
Air storageThe guide says to dry fully and store with air circulation.
No fixed fitAge or childbirth alone are not presented as a size rule.
What this site does
It turns cup claims into checkable inputs.
Menstrual cups are often discussed through broad claims: cheaper, cleaner, easier, better. Those words are not useful unless the assumptions are visible. Here, value means the relationship between verified product information, your buying pattern, your care routine and the current product price.
Cost examples with labels
Our examples are hypothetical. They show the formula and inputs so you can replace them with your own prices and period-product use.
Build a cost exampleCare before comparison
A cup that is not cleaned, dried or stored according to instructions should not be treated as having a predictable replacement date.
Review care stepsSource notes in plain English
We separate manufacturer-provided product facts from claims that are not supported in the supplied source pack.
Read source notesModel data you can actually compare.
The supplied MonthlyCup guide lists the following model measurements. Measurements can help narrow a choice, but the guide advises comparing individual flow and preferences. It does not say a model is guaranteed to fit everyone.
| Model | Diameter | Cup length | Total length | Capacity to holes |
|---|---|---|---|---|
| Mini | 37 mm | 45 mm | 55 mm | 15 ml |
| Normal | 43 mm | 55 mm | 65 mm | 22 ml |
| Plus | 47 mm | 55 mm | 65 mm | 43 ml |
How to use the guides
Read in the order a real decision happens.
Start with the money question, then check the care assumptions that make any value comparison meaningful, and finish by reviewing the product-fact boundaries.
Estimate your current baseline
Write down what you currently buy, how often you buy it, and the actual price you pay. If prices change, the estimate changes.
Add cup price and replacement uncertainty
Use the current shop price when you calculate. Do not assume a fixed lifespan unless you have a verified instruction or policy supporting it.
Check care and condition
MonthlyCup says to boil before first use and between periods as instructed, dry fully, store with air circulation and replace damaged, sticky or noticeably changed silicone.
