Results are estimates only. The values shown by this calculator are mathematical projections based on the inputs you provide. Actual returns from any savings account, CD, investment, or retirement account will vary based on market conditions, fees, taxes, inflation, and the specific terms offered by your financial institution.

Compound interest has been called the eighth wonder of the world. It means earning returns on your returns and it's the single most powerful force in wealth building. A $10,000 investment growing at 7% annually becomes $76,122 in 30 years without adding a single dollar.
Starting at 25 instead of 35 with $500/month at 7% annual returns means the difference between $1.2 million and $567,000 at age 65. That 10-year head start more than doubles the outcome not because of extra contributions, but because of compound growth.
The more frequently interest compounds, the more you earn. Daily compounding produces slightly more than monthly, which produces more than annual. The difference is small over short periods but adds up over decades.
A million dollars in 30 years won't have the same purchasing power as a million dollars today. Use the inflation rate option to see your investment's "real" value in today's dollars typically 2-3% inflation is a reasonable assumption.
Compound interest is interest earned on both your original principal and previously earned interest. Unlike simple interest, which only calculates returns on the original amount, compound interest creates an exponential growth effect over time.
More frequent compounding produces slightly higher returns. Daily compounding yields slightly more than monthly, which yields more than annual. Most savings accounts compound daily, while investments typically compound based on market returns.
