Frequently asked questions

Subtract expenses from income. 50,000 income with 40,000 expenses leaves a 10,000 surplus.

If expenses exceed income, the result is negative, meaning you are spending more than you earn.

Many aim for at least 20% of income, but any positive, consistent saving builds wealth over time.

Raise income, cut non-essential spending, or both, and review recurring costs regularly.
