1. What is the Investment Calculator With Annual Increase?

The Investment Calculator With Annual Increase calculates the future value of an investment that includes both an initial principal amount and regular annual contributions. It combines compound interest with annuity calculations to provide a comprehensive investment projection.

2. How Does the Calculator Work?

The calculator uses the investment formula:

\[ FV = P (1 + r)^n + Annual Increase × Annuity Factor \]

Where:

\( FV \) — Future Value (currency)
\( P \) — Initial Investment (currency)
\( r \) — Annual Interest Rate (decimal)
\( n \) — Number of Years
\( Annual Increase \) — Regular annual contribution (currency)
\( Annuity Factor \) — Factor from annuity tables

Explanation: The formula calculates the compound growth of the initial investment plus the accumulated value of regular annual contributions, accounting for the time value of money.
