NAD+ monthly vs four-week billing
A four-week charge repeats every 28 days. A calendar-month charge repeats 12 times a year. At the same advertised price, four-week billing has a higher annualized cost. Compare the full charge and the supplied quantity before deciding which plan costs less.
Put both quotes on the same calendar
A fictional $100 calendar-month plan costs $1,200 over 12 monthly payments. A $100 charge every 28 days annualizes to $1,304.46 using an average 365.25-day year. The difference is about 8.7%. Neither example is a provider offer. An annualized amount describes the repeating rate, while the charges appearing in your first year depend on the exact start and renewal dates.
Use the annual plan cost calculator to compare your actual quotes. Enter the whole recurring payment. If a plan takes $447 every three months, enter $447 for a three-month cycle. Dividing that payment into a monthly equivalent helps compare budgets; it does not turn the purchase into a monthly contract.
The payment calendar does not tell you the supply
A three-month payment could purchase one shipment or several. Ask for the number of containers, their quantity and the delivery schedule. Then compare the amount that you can use within the pharmacy’s instructions. A calendar calculation cannot settle whether a larger prepaid supply is suitable for your prescription.
The bmiMD review separates monthly equivalents from full plan charges. The CoreAge Rx review explains why a starting monthly price alone does not establish the prepaid total. Read the dated terms on each review; these examples are not promises about the quote offered to you.
| Calendar | Confirm in writing |
|---|---|
| Payment | Full charge, renewal interval and any introductory price |
| Delivery | Shipment dates and the quantity in each shipment |
| Use | Prescription and pharmacy instructions for your actual supply |
Check the price that renews
Record the first charge, the recurring charge, when any discount ends and whether fees recur. The FTC cautions that trial offers can lead to continuing charges and advises reviewing the terms before enrolling.[1] Save the checkout terms and cancellation instructions with the quote.
Ask what happens if treatment is not prescribed or the next shipment is no longer wanted. The subscription cost checklist separates consultation fees, shipping and cancellation questions. Do not assume that stopping a payment, canceling a subscription and changing a prescription are the same action.
Use two comparisons before choosing
First compare the full recurring budget. Then compare the confirmed quantity and what the service includes. A lower annualized subscription total is not enough if the quote leaves the medication quantity unresolved. Likewise, a lower cost per purchased milligram can hide supply you will not use.
The cost per milligram calculator handles a confirmed total price and milligram quantity. The unused supply calculator shows how an unused portion changes effective cost. These are financial comparisons; they do not establish equivalent treatment, clinical benefit or safety.
Are monthly and every four weeks the same?
No. Four weeks is 28 days; calendar months vary in length. At the same repeating price, the annualized costs differ.
Does annualized cost equal my first-year card charges?
Not necessarily. Payment dates, fees, discounts and prepaid commitments determine the actual charges. Annualization compares the recurring rate.
