Select the type of calculation you want to perform (Future Value, Present Value, Interest, etc.).
Click the "Calculate" button to see the result.
Review the result and use the "Reset" button to clear the form and perform another calculation.

The calculator will display the result in a clear format, along with a breakdown of the calculation.

Formula Explained

The C++ Money Calculator uses standard financial formulas to perform calculations. Here are the key formulas used:

Future Value Formula

FV = PV × (1 + r)^n

Where:

FV = Future Value
PV = Present Value (Principal)
r = Annual Interest Rate (in decimal)
n = Number of Years

Present Value Formula

PV = FV / (1 + r)^n

Where:

PV = Present Value
FV = Future Value
r = Annual Interest Rate (in decimal)
n = Number of Years

Interest Calculation

I = PV × r × n

Where:

I = Interest
PV = Present Value (Principal)
r = Annual Interest Rate (in decimal)
n = Number of Years

The calculator uses these formulas to provide accurate results based on the inputs you provide.

Worked Examples

Let's look at a few examples to see how the C++ Money Calculator works.

Example 1: Future Value Calculation

Suppose you invest $1,000 at an annual interest rate of 5% for 3 years. What will be the future value?

Using the Future Value formula:

FV = 1000 × (1 + 0.05)^3 = 1000 × 1.157625 = $1,157.63

The calculator will display the future value as $1,157.63.

Example 2: Present Value Calculation

You want to know the present value of a future amount of $1,500 at an annual interest rate of 6% over 4 years.

Using the Present Value formula:

PV = 1500 / (1 + 0.06)^4 = 1500 / 1.26247696 = $1,188.14

The calculator will display the present value as $1,188.14.

Example 3: Interest Calculation

Calculate the simple interest earned on a principal of $5,000 at an annual rate of 4% for 5 years.

Using the Interest formula:

I = 5000 × 0.04 × 5 = $1,000.00

The calculator will display the interest as $1,000.00.
