How do I teach credit, debt and interest to teenagers?

Short answer: Teach credit, debt and interest by starting with one number students can feel: what a $1,200 phone actually costs on a card at 24% APR when only the minimum is paid. Build the vocabulary out of that single calculation, then widen it to car loans, student debt, credit scores and buy-now-pay-later.

Step by step

How to teach it over a week

  1. Open with one shocking calculationWork out the true cost of a purchase paid off at the minimum, and let the total do the arguing.
  2. Build the vocabulary from that examplePrincipal, interest, APR, minimum payment and revolving credit all become concrete once students have seen the number.
  3. Compare good and bad borrowingPut a mortgage, a student loan, a car loan and a payday loan side by side and rank them with reasons.
  4. Finish with a decision, not a definitionGive students a realistic scenario and make them choose a payment plan and defend it in writing.

Make it work for everyone

Reaching every student in the room

Interest is a maths topic dressed as a life-skills topic, so weaker calculators will disengage unless the numbers are staged. Give the supported worksheet a completed first row and a formula reminder, and hand stronger students an amortization comparison. Written justifications, not just correct totals, show you whether students grasp why compounding hurts.

Good to know

Frequently asked questions

How much maths do students need before this works?

Percentages and a calculator will carry most of a week. Simple interest needs one multiplication, and compound interest works fine as a repeated calculation in a table before anyone meets the formula. If your group struggles with percentages, spend the first lesson on that, since every later idea rests on it.

Is any of this financial advice?

No, and it should not be presented that way. These are teaching resources about how credit, interest and scoring work, using illustrative figures. Rates, loan rules and credit scoring models differ by country and change over time, so tell students to check current terms and speak to a qualified adviser before making a real decision.

Will teenagers care about debt they do not have yet?

They care once it is their money and their purchase. Anchor everything in things they are close to buying, a phone, a used car, a first apartment deposit, or a course they are considering. Abstract lessons about interest rates lose the room; working out what a student's own planned purchase costs on credit does not.
