How to create amortization schedule in numbers

What kind of amortization schedule?

If you are talking about mortgages have a look at the Mortgage Calculator template at File > New in your menu.

If you are talking about something else, perhaps you could describe what you are looking for.

Numbers is good at this kind of thing, so it's mainly a question of understanding what you are trying to do. The more specifics you can give, the better.
