The same savings can make you very different amounts of money.

The big idea

Wealth is what you own minus what you owe. Grow it by spending less than you earn, investing the difference, and giving it time to compound.

Start by knowing where you stand. List everything you own (assets) and everything you owe (liabilities). The difference is your net worth. Check it at least once a year, and quarterly is even better.

The first ingredient is boring but essential: spend less than you earn. Cut subscriptions you don’t use, avoid impulse buys, build a budget, and grow your income with new skills, a raise or a side hustle.

Then invest, because saving alone won’t get you there. Put in $1,000 a year for 30 years and at 0% you have $30,000. At 5% you have about $70,000, and at 10% about $180,000. Same savings, very different outcome. That’s compounding: your returns start earning their own returns. Play with the numbers below.
