Future Value Formula:
From: | To: |
The Future Value (FV) calculation determines how much an investment made today (present value) will grow to at a future date based on a specified interest rate and time period. It's a fundamental concept in finance for evaluating investment opportunities.
The calculator uses the Future Value formula:
Where:
Explanation: The formula accounts for compound interest, where interest earned each period is added to the principal for the next period's interest calculation.
Details: Future Value calculations are essential for financial planning, investment analysis, retirement planning, and comparing different investment options. They help investors understand the time value of money.
Tips: Enter present value in USD, interest rate as a decimal (e.g., 0.05 for 5%), and time in years. All values must be positive numbers.
Q1: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus accumulated interest.
Q2: How often is interest compounded in this calculator?
A: This calculator assumes annual compounding. For different compounding periods, the formula would need adjustment.
Q3: What are typical interest rate ranges?
A: Rates vary widely - savings accounts might offer 0.5-2%, bonds 2-5%, stocks historically average 7-10% annually.
Q4: Can I calculate present value from future value?
A: Yes, by rearranging the formula: \( PV = FV / (1 + r)^t \). This is called discounting.
Q5: How does inflation affect future value?
A: Future value calculations typically don't account for inflation. For real (inflation-adjusted) returns, subtract expected inflation from the interest rate.
