Expert Tip

The historic inflation-adjusted return rate for the S&P 500 is approximately 7-8% annually.

How this Calculator Works

This calculator estimates the future value of an investment portfolio by combining initial capital, periodic deposits, and annual rate of return. It serves as an essential tool to model retirement accounts, education funds, or general brokerage accounts. Individual investors use it to verify savings paths.

Formula & Methodology

Future Value of Principal = Principal * (1 + r)^t Future Value of Annuity = PMT * [ ((1 + r)^t - 1) / r ] Total Future Value = Future Value of Principal + Future Value of Annuity - Principal is the initial deposit amount. - PMT is the regular annual contribution. - r is the annual rate of return (as a decimal). - t is the total duration of investment in years.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

You start with $5,000, add $1,200 annually, and earn an average return of 8% per year for 5 years. 1. Calculate future value of principal: $5,000 * (1 + 0.08)^5 = $7,346.64. 2. Calculate future value of contributions: $1,200 * [ ((1.08)^5 - 1) / 0.08 ] = $7,039.92. 3. Sum the parts: $7,346.64 + $7,039.92 = $14,386.56. Result: The projected total investment value after 5 years is $14,386.56.

FAQ

How does compounding frequency impact investment returns?
More frequent compounding (e.g. monthly or daily vs. annually) generates higher effective annual yields (APY) because interest is calculated on accumulated interest earlier in the period.
What is the difference between Sharpe Ratio and Sortino Ratio?
The Sharpe ratio divides excess return by total standard deviation (both upside and downside volatility), whereas the Sortino ratio divides excess return by downside deviation only.
Should investment calculators replace professional wealth management?
No. Investment calculators model financial mathematics under assumed growth rates. Actual market performance fluctuates, so consult a licensed financial planner (CFP) or RIA for personalized advice.
