The calculator uses the compound interest formula:
Where:
Explanation: The formula accounts for how interest compounds over time, with more frequent compounding leading to greater growth.
Details: Compound interest is the process where interest is earned on both the initial investment and the accumulated interest from previous periods. This creates exponential growth over time, making it a powerful force in retirement planning.
Tips: Enter your initial investment amount, expected annual return rate (as a decimal), how often interest compounds each year (e.g., 12 for monthly), and the number of years you plan to invest.
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 does compounding frequency affect growth?
A: More frequent compounding (e.g., monthly vs. annually) results in slightly higher returns due to interest being calculated on a more recent balance.
Q3: What's a realistic rate of return for an IRA?
A: Historically, stock market returns average about 7-10% annually, but this varies by investment mix and market conditions.
Q4: Are IRA contributions tax-deductible?
A: Traditional IRA contributions may be tax-deductible depending on your income and whether you're covered by a retirement plan at work.
Q5: When can I withdraw from a Traditional IRA?
A: Generally after age 59½ without penalty, with required minimum distributions starting at age 72.
