Step 1: Let's Learn

Read it, or press Listen and follow the words.

The order of financial priorities matters more than the size of any single decision.

A workable sequence

Cover essentials, claim the employer match, build a small emergency fund, clear high interest debt, then invest for the long term.

Why debt comes before investing

Clearing a 24% credit card is a guaranteed 24% return. No investment reliably offers that.

Net worth

Net worth is what you own minus what you owe. It can be negative early in life, and the trend matters more than the number.

Review it

A plan written once and never revisited stops matching your life. An annual review is enough.

Behaviour beats arithmetic

Spending less than you earn, consistently, matters more than any optimisation in this course.

A common ordering of priorities

Cover essentials, build a small emergency buffer, clear high-interest debt, capture any employer retirement match, then build longer-term savings. The ordering follows from comparing interest rates and risks, not from preference.

Why high-interest debt comes first

Clearing a balance charging 20% is a guaranteed 20% return, which exceeds what any ordinary investment reliably offers. The arithmetic makes this the clearest decision in personal finance.

Plans need revisiting

Income, costs and goals all change. A plan reviewed annually stays connected to the situation; one written once becomes inaccurate quietly, usually in the direction of underestimating costs.

What this course does and does not provide

It teaches how the arithmetic works and what the terms mean, so that offers can be compared and claims checked. It does not recommend particular products, and decisions with significant sums generally warrant a qualified professional.

Step 2: Try It Yourself

Tap and try it out.

Assets against debts. Net worth is the gap between them, and the goal is for that gap to grow.
Assets250
Debts180

Assets has the most. It has 70 more than Debts.

Step 3: Watch an Example

One step at a time.

Watch Ines Order Her Money

Ines has $500 a month spare, a 5% employer match available, and a credit card at 24%.

  1. Step 1

    She contributes enough to capture the full match, since it doubles instantly.

Step 4: Your Turn

Practice makes it stick.
