How the projection works

Whole tax years, in order, with growth exactly as you set it.

Landfall works in whole tax years, each running from April to April, which is when your allowances start again. Within a year it takes income first, then growth, then spending, then tax, and carries what is left into the next year.

Growth is applied exactly as the plan sets it, every year, with no good years and no bad ones. That is deliberate. It is what makes two plans comparable, because the only thing that differs between them is the thing you changed.

Markets do not behave that way, which is what the stress test is for.

Every chart, table and sentence names a year in full, as the tax year it is. A day in someone’s life, such as the last day of work, is given as a date.

A person’s age for a year is the age they reach by its last day. Each person’s plan runs to the end of the tax year in which they reach their “Plan to age”. A switch in “Edit plan”, on for a new plan, plans everyone to the same long age in place of each person’s own. Nobody knows how long they will live, and a longer plan has more years to pay for. The ages typed are kept for when it is turned off. What starts on a birthday — the State Pension, a final salary pension, the first day a pension can be drawn — starts on that day, and the year it falls in counts only the part after it.
