Written in house

Every guide is researched and written by our editorial team, not rewritten from a lender’s marketing page.

Reviewed on a schedule

Each guide carries the date of its last review, and we publish the date even when nothing changed.

The arithmetic is shown

Where a figure comes from a formula we print the formula, so you can check it rather than trust it.

Twelve languages, twelve markets

Each market page uses its own currency, rate convention and purchase taxes, not a translated American default.

Nothing is sold to you

We do not lend, we take no fee from readers, and the calculator sends nothing anywhere.
