What is compound interest?

Compound interest is interest earned on both your original deposit and previously earned interest. Unlike simple interest, compound interest causes exponential growth over time. A 25-year-old investing $200/month at 7% will have ~$525,000 by 65. Starting at 35 with the same amount yields only ~$243,000. Use the savings goal calculator to set a specific target, and track your subscriptions to find money to invest.
