Guides

Each guide answers one question about paying off a mortgage or other loan: what the number is, how to work it out yourself and what to do next. Where a guide needs a figure, it walks through a worked example and, when it helps, gives you a small tool for your own numbers.

Every figure comes from the same math as the site's calculators and goes through the same independent checks, explained on the calculation method page. Rules come from official sources, which each guide links, and each guide shows when it was published and last reviewed.
