How to understand debt and interest and pay it off faster

Understand what borrowing really costs.

A course on how interest and repayment work, with simple examples. It covers comparing the cost of different kinds of borrowing, seeing how repayments interact with interest over time, and asking the right questions before signing, without recommending any product.

A starting goal

I want to understand how interest and debt repayment work. Use simple examples to compare borrowing costs and common repayment approaches without choosing a financial product for me.

Change any word so it fits your situation. The course is built from what you type and a few setup questions.

Three things you can do before the course exists.

Useful on their own. The course is for when you want the whole skill, not just the first move.

  1. Separate the interest from the repayment

    Invented example: a $1,000 balance charged 2% for one month adds $20 interest. A $60 payment then leaves $960: 1,000 + 20 - 60. This simplified model has no fees or new purchases. Real agreements may calculate interest daily and apply payments differently.

  2. Compare cost and consequences

    List balance, rate, fees, due date and the consequence of missing each payment. Paying extra toward the highest rate can reduce interest, but housing, essential services, secured debts or legal obligations may need separate priority advice. A rate alone cannot rank every real-world consequence.

  3. Check a proposed repayment plan

    Ask whether the payment covers interest and reduces principal. In the example, only $40 of the $60 reduces principal. If required payments are unaffordable, contact the lender and a reputable local debt adviser. Do not assume a smaller monthly payment means a cheaper loan.

Before the course is built

Setup asks about your situation first.

Lesson 1 opens on the moment you describe, and the examples use your role. For this request, expect questions like these.

  1. Do you have debt now, or are you deciding whether to borrow?
  2. Which kinds are involved: credit cards, loans, a mortgage, or buy-now-pay-later?
  3. How comfortable are you with percentages and simple arithmetic?

Right for now

If any of this sounds familiar, start here.

The balance does not seem to move

You pay every month and the number barely changes.

APR and interest rate blur together

The terms on the paperwork mean nothing definite to you.

You are about to borrow

An offer is in front of you and you want to understand it before agreeing.

Course arc

Where the course goes, in order.

Cadence writes the lessons for you, so the exact path follows your answers. This is the ground a course built from this sentence covers.

01 / 06

What interest is

How simple and compound interest differ, with explicit assumptions.

Rates, APR and fees

Reading the numbers on an offer and what each one includes.

Why balances barely move

Minimum payments, interest and the arithmetic of slow repayment.

Comparing kinds of debt

Cards, loans, mortgages and installments, on a like-for-like basis.

Repayment approaches

Common ways people order and pace repayment, and what each trades off.

Questions before you sign

What to ask about any offer, and the answers that should give you pause.

What changes

What you will be able to do, and what you will stop believing.

You will be able to

Explain how interest accrues

See why balances grow the way they do and what a rate actually means.

Compare borrowing costs

Put different offers on the same footing.

Understand repayment choices

See what changes when you pay more, sooner, or on a different debt first.

Ideas this course corrects

A low monthly payment means a cheap loan

Compare total repayment, fees and duration as well as affordability. A longer term can increase total interest.

The highest rate always comes first

Interest cost is one consideration. Essential living costs, default consequences and local debt rules can change the priority.
