Same medicine. One aisle over, and the tax changes.
The same drug, taxed or exempt depending on whether someone wrote it down.
Medicine your doctor prescribes is almost never taxed. Medicine you pick off the shelf yourself usually is, at the normal rate, like a shampoo or a snack. What decides it isn't the drug. It's whether somebody wrote you a prescription for it. So the very same ingredient can be untaxed at the pharmacy counter and taxed a few steps away. If you buy something regularly for a long-running problem, that adds up quietly.
Prescription medication is exempt from sales tax almost everywhere. Over-the-counter medication generally is not — it is taxed as an ordinary retail good, at the full standard rate, in most states. The line is drawn by the prescription rather than by the medicine, which produces the odd result that the identical active ingredient can be exempt in one aisle and taxable in the next. For a household managing a recurring condition with a non-prescription remedy, that distinction is a real and repeated cost.

Prices and wages are held at today's levels, and the return above is inflation-adjusted to match — consistent by design. The invested-instead line assumes the cash is contributed at the end of each year and left alone; it is an alternative use of the same money, never an extra cost on top.
Your position in the tax system
29.65% on the next dollarEvery extra dollar you earn is taxed at your marginal rate, not your average one — which is why a purchase costs more to fund than a paycheck stub suggests.
Marginal rates are read in gross-income terms: below the standard deduction an extra dollar of pay adds nothing to taxable income, so the true rate there is 0%, not the lowest bracket's. Excludes pre-tax deductions (401(k), HSA), which would lower all three.

Where every dollar goes

Each tax layer is the extra tax this purchase causes — that layer's tax at your income subtracted from its tax at your income plus the gross-up — so bracket boundaries the purchase straddles are handled correctly rather than smoothed over with an average rate.
Is a raise actually a raise?
you keep 70%A raise arrives on top of everything you already earn, so it is taxed at your marginal rate — not the average rate on your whole salary.
Federal, FICA, state and any local income tax — no pre-tax deductions, benefit changes, or payroll withholding quirks, all of which move the real figure. Moving into a higher bracket never taxes the income below the threshold: only the dollars above it pay the higher rate.

Questions people ask
Why does a small regular cost need such a big salary behind it?
It comes out of take-home, and take-home is what survives tax. Each repeat has to be earned in full before tax, which is why a modest monthly figure needs a much larger salary standing behind it.
Does this cost the same in every state?
No — the tax on it is set state by state, and this figure follows whichever one you pick. Some states exempt this category outright, some tax it at a reduced rate, and some apply the full rate, so the same purchase can land in three different places.
What does this figure leave out?
Specific things, named below rather than glossed over. Where the real rule has an edge this model does not follow, the note says so, so you can judge whether your purchase falls inside it.
Why does a recurring outlay require disproportionate gross income?
Consumption is funded from post-tax income, so required gross income is the outlay divided by one minus the marginal rate on the relevant income slice. For a recurring cost that grossed-up figure recurs at the same cadence, which is why annualised gross requirement exceeds the nominal annual outlay by the full marginal wedge.
How does state tax treatment vary for this purchase?
Sales tax treatment of this category is determined at state level, with local add-ons layered on top where they exist. Classification varies between full exemption, a reduced grocery-style rate and the standard rate, so aggregate burden is not comparable across states without specifying the jurisdiction.
What are the stated limits of this category's model?
Modeling limits for this category are stated explicitly on the page rather than inferred. They typically concern classification edge cases, per-item caps, or local levies outside the modeled base. Where a limit applies to a reader's specific purchase, the figure should be treated as a lower or upper bound as the note describes.
