Our investment calculator uses your input parameters to project the future value of your investments. It takes into account your initial investment, regular contributions, expected annual rate of return, investment time horizon, tax rate, and inflation rate to provide a comprehensive estimate of your investment growth.

The calculator uses compound interest formulas to model the growth of your investments over time, assuming that your contributions are made at the end of each month and that your returns are compounded annually.

The annual rate of return is the percentage increase or decrease in the value of your investment over a one-year period. This rate reflects the average annual growth you expect your investment to achieve. For example, if you invest $1,000 and it grows to $1,070 after one year, your annual rate of return is 7%.

When estimating your annual rate of return, it's important to consider the type of investments you're making. For example, stocks historically have an average annual return of around 7-10%, while bonds typically have lower returns. Keep in mind that past performance is not indicative of future results.

The difference between pre-tax and post-tax contributions lies in when your contributions are taxed:

• Pre-tax contributions (e.g., Traditional IRA, 401(k)) are made with money that has not yet been taxed. This reduces your taxable income in the year you contribute, but withdrawals in retirement are taxed as ordinary income.
• Post-tax contributions (e.g., Roth IRA, Roth 401(k)) are made with money that has already been taxed. Contributions are not tax-deductible, but qualified withdrawals in retirement are tax-free.

When you select the "Pre-tax contributions" option in the calculator, it assumes that your contributions reduce your taxable income now, but your investment growth and withdrawals will be taxed. If you don't select this option, the calculator assumes your contributions are made with after-tax dollars, and only the investment growth is taxed upon withdrawal.

Inflation is the rate at which the general level of prices for goods and services is rising, and subsequently, purchasing power is falling. Over time, inflation reduces the value of money. For example, if the inflation rate is 2% per year, $100 today will be worth the equivalent of $98 next year.

When you adjust for inflation in the calculator, it shows your investment's future value in today's dollars, accounting for the eroding effect of inflation. This gives you a more realistic idea of what your money will be able to buy in the future. If you don't adjust for inflation, the future value represents the nominal value of your investment without considering the loss of purchasing power.

For long-term investments, it's important to consider inflation because even a relatively low inflation rate can significantly reduce the purchasing power of your money over time.

The investment calculator provides estimates based on the information you provide. While it uses standard financial formulas to project investment growth, it's important to understand that actual investment results may vary significantly from these estimates due to several factors:

• Market fluctuations can cause the actual rate of return to be higher or lower than the rate you enter.
• Investment fees and taxes may be higher or lower than assumed.
• Inflation rates may differ from the rate you enter.
• You may not maintain a consistent contribution schedule.
