Compare the cash behind a subscription.

A four-week plan and a monthly plan do not share the same payment calendar. Compare two written quotes before choosing a commitment.

Today counts as a payment date.

This tool counts bills in the first 365 days from today for four-week plans, and the first 12 calendar months for monthly plans. It assumes unchanged prices and automatic renewal of the same package. The anniversary is excluded.

Your first-year cash comparison

Why the numbers differ

For a four-week plan, bills occur at day 0, 28, 56 and so on. A one-cycle plan therefore has 14 payment dates before day 365, including day 364. A calendar-month plan has 12 payment dates before its first anniversary. This cash window differs from an annualized average cost.

Invoice = quoted cycle price × cycles prepaid + extra per-invoice fees. First invoice adds the one-time fee. Total cash = invoice × invoice count + one-time fee. A 12-cycle four-week block covers 336 days, so a second full block is billed on day 336 if the same offer renews. Calendar-month blocks use month boundaries and do not estimate exact dated payment days.

Blank dollar fields remain unknown. This assumes the displayed per-cycle equivalent multiplies to the package invoice; confirm that with the seller. Any financing installments, price changes, taxes, discounts, per-shipment charges outside the quote, refunds and cancellation deadlines are excluded. The tool does not predict treatment duration, dosing or eligibility. It does not say that the two products are medically equivalent.
