Principal + APR + term

Understand why every loan can be described by three variables: Principal (how much), APR (at what rate), Term (over how long).

In this lesson

Principal + APR + term is part of Loan Cost Lab. This preview shows how credit-debt connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.
