When does the rolled up balance double?

With a lifetime mortgage you usually pay nothing each month, so the interest is added to the balance and that balance grows every year. This tool shows the age at which what you owe reaches double the amount you released, and the years where it hits other milestones, so the compounding is easy to picture.

Assumptions: interest is compounded once a year on the amount released plus any fees added to the loan, at a fixed rate, with no repayments. A real plan may compound monthly, may let you pay interest to slow the growth, and may offer drawdown so you borrow in stages. The starting year is taken as the current calendar year. This shows the shape of compounding, it is not a quote.
