Formula Used

The Money Millionaire Calculator uses the following formula to calculate the time required to become a millionaire:

Future Value = Current Savings + (Monthly Contribution × ((1 + (Annual Return / 12))^(Number of Months) - 1) × (1 + (Annual Return / 12)))

Where:

Future Value is the target amount ($1,000,000)
Current Savings is your initial savings amount
Monthly Contribution is the amount you add each month
Annual Return is the expected annual return on investment (expressed as a decimal)
Number of Months is the time required to reach the target

The calculator solves for the number of months required to reach $1,000,000 based on your inputs.

Worked Example

Let's say you have $50,000 saved up, contribute $1,000 each month, and expect a 7% annual return. Here's how the calculation works:

Future Value = $50,000 + ($1,000 × ((1 + (0.07 / 12))^120 - 1) × (1 + (0.07 / 12)))

Calculating step-by-step:

Convert annual return to monthly: 0.07 / 12 ≈ 0.005833
Calculate the future value of monthly contributions: $1,000 × ((1.005833)^120 - 1) × 1.005833 ≈ $1,000 × (1.93 - 1) × 1.005833 ≈ $1,000 × 0.93 × 1.005833 ≈ $935,000
Add current savings: $50,000 + $935,000 ≈ $985,000

This means it would take approximately 10 years to reach $1,000,000 with these inputs.
