Frequently Asked Questions (FAQ)

Q: How do regular contributions impact the final value?

A: Regular contributions, even small ones, significantly accelerate compounding. They add to your principal, allowing your interest to earn interest on a larger and larger sum over time, leading to exponential growth. It's often more impactful than a large initial investment alone.

Q: Why is inflation-adjusted return important?

A: Inflation causes money to lose its purchasing power over time. A 7% return is great, but if inflation is 3%, your real return is only about 4%. The inflation-adjusted calculation shows you the true value of your future money in today's terms, giving you a more realistic view of your financial growth.

Q: How does the "After-Tax Future Value" work?

A: Most investment gains are subject to taxes. This calculation estimates your earnings after a specified tax rate is applied annually, providing a more accurate picture of your net worth. It helps you understand the impact of taxes on your long-term wealth accumulation.

Q: Is my data saved privately?

A: Yes. Your portfolio scenarios are securely stored in a private Firebase database linked to a unique user ID, which is automatically assigned to you. Your data is not publicly accessible and is associated only with your unique identifier, ensuring your privacy.

Q: What is the Rule of 72? How can it help me?

A: The Rule of 72 is a mental shortcut to estimate the number of years required to double your money at a given annual rate of return. You simply divide 72 by the annual interest rate. For example, at a 10% rate, your money would double in approximately 7.2 years ($72 \div 10 = 7.2$).

Q: How do investment fees and commissions affect my returns?

A: While this calculator doesn't have a specific input for fees, you can account for them by slightly lowering the Annual Interest Rate. For example, if you expect a 7% return but pay 1% in annual fees, you should calculate using a 6% rate. Fees, even small ones, can have a significant negative impact on long-term growth.

Q: Can I use this calculator to plan for my debt?

A: Yes! You can use the main calculator by viewing your debt as a negative principal and your payments as a negative contribution. Or, more simply, use our dedicated Debt Repayment Calculator to see how quickly you can pay off your loan with regular payments. The principle of compound interest works in reverse against you with debt.

Q: Does compounding frequency make a big difference?

A: Yes. The more frequently interest is compounded, the faster your money grows. While the difference between daily and monthly compounding might seem small over a few years, it can become quite significant over a long time horizon, as your interest starts earning interest sooner.

Q: What is the difference between APR and APY?

A: APR (Annual Percentage Rate) is the simple interest rate, not accounting for compounding. APY (Annual Percentage Yield) is the effective rate that includes the effect of compounding. APY is always equal to or higher than the APR. For investment calculations, APY is the more accurate measure to use.

Q: Why are my investments and contributions separate in the chart?

A: The chart visually separates your total contributions from the total interest you've earned. This helps you clearly see the "snowball effect" of compound interest. Over time, you'll notice that the interest portion of your portfolio begins to grow faster than your own contributions, demonstrating the power of passive income.
