Future Value Calculator
(Estimate how much your money will grow over time with compound interest!)
Enter Your Investment Details:
Initial Investment (Principal): $_______ (amount you start with)
Monthly Contribution: $_______ (optional; regular savings)
Investment Timeframe: _______ years (e.g., 10, 20, 30 years)
Expected Annual Return (%): _______% (e.g., 7% for stock market average)
Compounding Frequency:
🟢 Annually | 🟢 Quarterly | 🟢 Monthly | 🟢 Daily
Calculate Your Future Value:
📈 Total Invested: $_______ (principal + contributions)
💰 Future Value: $_______ (total projected growth!)
🚀 Interest Earned: $_______ (future value – total invested)
(How much your money could grow over time!)
How It Works:
Compound Interest Formula:
FV = P × (1 + r/n)^(nt) + (PMT × [(1 + r/n)^(nt) – 1]/(r/n))
P = Principal, *r* = annual rate, *n* = compounding periods/year, *t* = years, PMT = monthly contribution.
Example (5-Year Investment):
Initial: $10,000 | Monthly: $100 | Return: 7% | Compounded Monthly
Future Value: ~$18,240 (Interest earned: ~$2,240)
Key Factors:
Time: More years = exponential growth.
Contributions: Regular deposits boost results.
Rate of Return: Higher % = faster growth (but riskier).
Why It Matters:
✔ Retirement Planning: See how 401(k) or IRA contributions grow.
✔ Goal Savings: Calculate for a house, education, or big purchase.
✔ Debt Payoff: Compare investing vs. paying off loans.
Try It:
🔹 $5,000 + $50/month for 20 years at 6% → $_______
🔹 $20,000 lump sum for 30 years at 8% → $_______
(Note: Adjust for inflation—today’s $1M ≠ future $1M!)
Tip: Use “Rule of 72” to estimate doubling time (e.g., 7% return ≈ 10.2 years).
