Start Early
Starting at 25 vs 35 means 10 extra years of compounding. That can double your final amount with the same monthly contribution.
Calculate how much your money will grow over time with compound interest. Enter a starting amount, interest rate, time period, and optional monthly contributions to project your future wealth.
Future value is what your money will be worth at a point in the future, given a rate of return. It's the fundamental concept behind all investing and retirement planning.
The magic is in compounding: your gains earn their own gains. With 7% annual returns, $10,000 becomes $38,697 in 20 years — even without adding a single dollar. Add $200/month and it balloons to $142,510.
Einstein allegedly called compound interest the "eighth wonder of the world." Start early, contribute regularly, and let time do the heavy lifting.

Dollar-cost averaging through regular contributions smooths out volatility and harnesses compounding most effectively.
Even 1% higher returns compound dramatically over decades. $10K at 7% for 30 yrs = $76K. At 8% = $100K. That's 32% more!
$500/mo for 30 years at 7% = $566,764. With employer match doubling to $1,000/mo = $1,133,529. Start ASAP.
$200/mo for 18 years at 6% = $76,845. Starts at birth to benefit from full compounding period for education costs.
$500/mo for 5 years at 4% HYSA = $33,165. Enough for a down payment on a starter home in many markets.
$300/mo for 12 months at 5% HYSA = $3,682. Building 3-6 months of expenses creates crucial financial security.
$1,000/mo into index funds at 10% for 25 years = $1,180,244. Millionaire status through discipline and compounding.
Aggressive saving (50-70% of income) into investments to reach 25× annual expenses and retire in 10-15 years.
Future value is the amount of money an investment will be worth at a specific date in the future, based on the assumed rate of growth. It accounts for compound interest, making your money grow exponentially.
For stocks: 7-10% (S&P 500 historical average). For bonds: 3-5%. For HYSA: 4-5%. For conservative planning: use 6-7% to account for inflation and market variability.
Subtract inflation (2-3%) from your expected return for "real" returns. 10% nominal − 3% inflation = 7% real return. Your money grows, but each dollar buys less over time.
Time is the most powerful factor. $200/mo at 7% for 40 years = $528,000. Wait 10 years and invest $300/mo at 7% for 30 years = $353,000. Starting early with LESS beats starting late with MORE.
No. Future value is a projection based on assumed returns. Actual results depend on market performance, inflation, fees, and other factors. Use conservative estimates for planning.
