Investment Calculator

Calculate the future value of your investment with optional monthly contributions and compound returns.

FV = Initial x (1 + r/12)^(12xyears) + Monthly x [((1 + r/12)^(12xyears) - 1) / (r/12)]
$10,000 initial + $500/month at 8% for 20 years: Future value = $304,505, Total contributions = $130,000, Total gain = $174,505 (134% ROI)

What is a good rate of return on investments?

S&P 500 historically returns ~10% annually long-term. Conservative estimates use 7-8% (accounts for fees, inflation). Bonds return 3-5%, real estate 8-12%, high-yield savings 4-5%. Diversified portfolio: 60% stocks / 40% bonds typically returns 7-8%. Higher returns = higher risk. Young investors can take more risk.

Should I invest in stocks or bonds?

It depends on age and risk tolerance. Young (20s-40s): 80-90% stocks for growth. Middle age (40s-50s): 60-70% stocks, 30-40% bonds. Near retirement (60+): 40-50% stocks, 50-60% bonds for stability. Common rule: bonds = your age (e.g., age 40 = 40% bonds). Adjust based on risk comfort.

What are index funds and why invest in them?

Index funds track market indexes like S&P 500. Benefits: low fees (0.03-0.2% vs 1%+ for managed funds), automatic diversification, consistently outperform 80-90% of actively managed funds long-term. Warren Buffett recommends them for most investors. Easy way to invest without picking individual stocks.

How often should I check my investments?

Quarterly or semi-annually is sufficient for long-term investors. Daily checking leads to emotional decisions and panic selling during dips. Markets fluctuate - what matters is 10-20 year trajectory. Rebalance annually. Focus on continuing contributions, not daily values. Time in market beats timing the market.
