Compare the full program cost
A lower advertised monthly price can mean a larger upfront payment. Enter two written quotes to compare introductory prices, renewals and separate fees. Nothing is saved or sent to a provider.
Use the whole invoice
If a yearly plan advertises $150 per month but charges $1,800 upfront, select annual prepayment and enter $1,800. Add membership only when it is billed separately.
Four weeks is not a month
The planning model uses 13 four-week invoices over 52 weeks, or 12 monthly, four quarterly or one annual invoice. These are annualized comparison conventions, not a calendar schedule of payment dates.
Keep the assumptions visible
Only the first invoice gets the introductory price. Renewal rates stay constant, membership is counted 12 times, and one-time fees once. Dose changes, taxes, shipping and cancellation charges are excluded unless you include them in a quote.
Arithmetic only, not a price quote or medical advice. Initial outlay assumes the first membership charge and one-time fees are due with the first invoice. It does not measure refund eligibility, the total contractual liability of an installment plan or treatment suitability. Confirm those separately.
