How should your pot pay your income?

This choice changes how much you need more than any other.

Use a withdrawal rate

Needs a bigger pot. You take a set share of it each year, so it should last and may keep growing.

Withdrawal rate

Let your pot run down by an age you choose

Needs a smaller pot. It pays your income until that age, then it is used up.

Pay my income until age

Min. 75

Using a Withdrawal Rate means withdrawing a certain % of your retirement pot per year. Many opt for 4% as a rule of thumb, with the idea that a retirement pot invested in low-cost index funds should slightly grow each year, despite the withdrawals (and fees). The idea is that your retirement pot becomes sustainable and should never run out.
