Every 28 days is not once a month: compare the billing calendar
A plan billed every 28 days reaches its next charge sooner than a calendar-month plan. Compare dated payments over the same period, rather than treating both advertised rates as twelve identical monthly bills.[1]
What this comes down to
- A four-week interval is 28 days; thirteen intervals cover 364 days.
- Count the signup payment separately from later renewals.
- The billing date and the shipment date may be different.
Build a calendar before comparing totals
Remedy Meds says its initial payment occurs at signup and its billing renews every 28 days. That is a concrete example of a recurring interval, not a claim that every GLP-1 seller bills this way. Ro separately offers a plan described as billed every month.[1][2]
The arithmetic is useful only when the boundaries are explicit: 13 × 28 = 364 days. If signup is day 0 and every scheduled renewal occurs, charges fall on days 0, 28, 56 and so on through day 364. That is 14 payment events within days 0–364, counting signup. Thirteen four-week service periods are not the same thing as thirteen renewals after an initial payment.
| Billing promise | How to compare |
|---|---|
| Every 28 days | Generate each date from signup in 28-day steps |
| Every calendar month | Use the actual monthly renewal dates |
| Annual prepayment | Record the upfront charge and annual renewal separately |

Do not use the shipping calendar as a billing calendar
Remedy Meds requires a completed refill form before a prescription ships. A reminder to complete that form does not establish the next debit date. Ask support for both schedules and whether a delayed shipment changes billing.[3]
The FTC advises reviewing recurring-charge terms and keeping cancellation records. For a short trial, add a reminder before the contractual cutoff; for a longer purchase, list every scheduled charge across your chosen comparison window.[4]
For the broader purchase terms, see our subscription traps guide. Use this calendar exercise alongside it, especially when comparing a four-week supply with a monthly care fee.
Ask for dates, not just a monthly label
- What is the signup charge date and the first renewal date?
- Is the recurring interval 28 days, a calendar month or a prepaid term?
- Does delayed clinical review or delivery move the next payment?
- Which cancellation deadline applies to the next dated charge?
If the plan requires prepayment, also check how prepaid plans split shipments before counting the whole purchase as a single delivery.
Questions people actually ask
Does every 28-day plan charge thirteen times a year?
Do not assume that from the interval alone. Thirteen intervals span 364 days, but a count of payments depends on whether signup is included and where the comparison period starts and ends.
Does a four-week supply mean monthly billing?
No. Ask for the subscription interval separately from the medication quantity and shipping schedule; those terms describe different parts of the purchase.
