How the plan is worked out
There are three pieces of arithmetic on this page and they are all multiplication. What a day costs is what you get through in a day, divided by how many come in a pack or a tin, times what the pack or tin costs — the plan prints that division on the sheet with your own numbers in it. The money lines are that daily figure times 7, 28, 84 and 365 days. The check-in dates are your quit date plus 1, 3, 7 and 30 days, and one more on 31 October if your quit date falls inside the campaign month. Nothing is compounded, no inflation is applied, and no price rise is assumed: the figures say what the same habit at the same price would have cost over that many days, which is an assumption stated rather than a forecast made.
The taper schedule is ours and nothing published stands behind it. It runs the number of days you chose, ending the day before the quit date, split into blocks of roughly equal length. Each block gets a flat daily allowance stepping evenly down to nothing: with four blocks those allowances are four fifths, three fifths, two fifths and one fifth of what you get through now, rounded, with a floor of one. No health body prints a taper table, and the reason is in the evidence — the Cochrane review of 51 trials and 22,509 people found "moderate-certainty evidence that neither reduction-to-quit nor abrupt quitting interventions result in superior long-term quit rates when compared with one another", so there is no schedule to copy and this one claims to be nothing more than an even ramp with a date on it.
The default quit date is fourteen days out, which is not a house preference either. Smokefree.gov's own quit-plan builder asks for "a day in the next two weeks", and that is the window this form opens on.
The moves beside each trigger, and the five on the wallet card, are the practical half of smokefree.gov's own craving list — water, something to chew, slow breathing, exercise, a podcast or a game, ringing somebody, and being somewhere the habit does not live — applied to the moment you picked. They are suggestions, not a treatment, and nothing here measures whether any of them worked.
What this page does not do: it makes no claim about a body, at any point on the plan, the card or the calendar. A calendar entry outlives the page that made it and cannot be corrected once it is in a phone, so every milestone title marks a length of time and asks for a check-in rather than stating what has happened to you by then.

explains a calculation. Where a number here is our own judgement rather than a published figure, the
note says so and cites nothing; where the health bodies disagree, it carries the disagreement.
