Sermorelin billing calendar
See when a confirmed recurring payment falls and spot months with more than one charge. Enter the plan’s dates and recurrence; the calendar does not look up a provider’s policy.
A billing cycle is not a calendar month
A plan that bills every four weeks renews every 28 days. The payment date moves through the calendar, and some months can contain two charges. A monthly plan follows a calendar-month rule instead. These are different financial schedules even when the advertised figure looks the same.
Use the monthly-equivalent calculator when you want to compare rates. Use this calendar when you want to see which dates and calendar months contain payments. The result lists dates within your chosen inclusive range; it does not round a partial period up into another payment.
The HealthSource review records a charge every four weeks, a useful reminder to check the actual renewal dates. The Luvo Health review separates an introductory four-week charge from later renewals. Those are published terms, not confirmed future schedules: enter only the dates and amount that apply to your own agreement.
Illustration only, not a provider’s schedule
Jan 1–Dec 30, 2026: 13 payments × $99.00 = $1,287.00
Every 28 days from January 1 puts another payment on December 31. Including that date produces 14 payments. A monthly schedule from January 1 through December 31 produces 12. The endpoints change what the ledger counts.
Confirm how a monthly date moves
Monthly original-day mode returns to the day of the first payment whenever that day exists. January 31 becomes February 28 in 2026, then March 31. January 30 becomes February 28, then March 30. It calculates each date from the original anchor rather than letting February’s shorter month move every later payment to the 28th.
Month-end mode uses the last date of every month. It requires a month-end first payment and a provider-confirmed month-end rule. Starting on February 28 does not establish that the next payment will be March 31: original-day mode would produce March 28. If the terms do not settle that difference, ask the provider rather than choosing whichever result you prefer.
The calendar does not infer business-day rules, public holidays, bank processing, time zones or a billing clock time. A date is not a guaranteed payment instant. It also does not represent when to take medication, when a prescription runs out or when a shipment will arrive.
Count only the dates and charges you know
The first payment date and last date are both included. A payment exactly on the last date counts; the next payment outside the range does not. A narrow change to the end date can therefore add a whole charge. Choose the period that matches your planning question instead of assuming every twelve-month range contains the same count.
The optional amount must apply to every listed payment. If an introductory charge differs from the renewal, start with the first regular renewal or leave the amount blank. The displayed sum covers only those identical entered charges. It excludes unresolved fees, price changes, taxes, refunds and other commitments, so it is not a complete budget.
Our guide to advertised and renewal prices explains why a promotional figure should not be carried into every future charge. For a broader financial estimate, use the plan cost calculator. For missing terms, prepare a question list with the quote checklist.
Payment dates and cancellation deadlines are separate
Once the next charge is confirmed, the notice deadline helper can work back from the payment date, clock time, time zone and written notice window. This calendar has no clock time and cannot supply that cutoff by itself.
Read the plan’s cancellation and refund terms before assuming that the last date in your ledger stops later charges. Choosing an end date here does not cancel anything or alter an agreement. The tool saves no entries and sends no reminders; keep the provider’s written schedule if you need a reliable record.
