How do I calculate investment returns?

Investment returns are calculated using the formula: Future Value = Present Value × (1 + r)^n, where r is the annual return rate and n is the number of years. Regular contributions use a more complex formula: FV = P(1+r)^n + PMT × [(1+r)^n - 1] / r.

What's a realistic annual return rate?

Historical stock market returns average 7-10% annually. Bonds typically yield 3-5%. Conservative portfolios might aim for 4-6%, while aggressive growth portfolios might target 10-12%. Past performance doesn't guarantee future results.

How does inflation affect my investment?

Inflation reduces the real value of your returns. If your investment earns 7% but inflation is 3%, your real return is only 4%. For long-term planning, use an inflation-adjusted rate to see true purchasing power growth.

Frequently Asked Questions

What return rate should I use?

Historical stock market returns average 7-10% annually over long periods. Conservative estimates use 6-7%, aggressive use 10-12%. Bonds typically return 4-6%. Your actual return depends on your investments, timeframe, and market conditions. Past performance doesn't guarantee future results.

Why account for inflation?

Inflation reduces purchasing power over time. A 3% inflation rate means $100,000 in 20 years buys what $55,000 buys today. The calculator shows both nominal (stated) and real (inflation-adjusted) values so you understand what your money will actually be worth.

How much should I save for retirement?

Financial experts often recommend saving 10-15% of income for retirement. This calculator helps you see what different savings rates produce. A $500/month contribution for 30 years at 8% grows to about $680,000 - enough for many retirement goals.

What's the difference between nominal and real returns?

Nominal returns are the stated percentage growth. Real returns subtract inflation and show actual purchasing power. If you earn 8% and inflation is 3%, your real return is about 5%. Real returns matter for understanding what you can actually buy with your money.

Should I invest in stocks or bonds?

Stocks historically offer higher returns (7-10%) but more volatility. Bonds offer lower returns (4-6%) but more stability. Younger investors often hold more stocks for growth; older investors shift toward bonds for stability. A balanced portfolio mixes both.

How often should I review my investments?

Review your portfolio at least annually. Rebalance if allocations drift from your targets. Don't panic over short-term drops - markets recover over time. Consider increasing contributions when income rises. Stay consistent with your long-term plan.
