Formula Used
The calculator uses the following formula to determine the monthly investment needed:
Monthly Investment Formula
Monthly Investment = (Savings Goal - (Monthly Income - Monthly Expenses) × Timeframe) / (Timeframe × 12)
Where:
- Savings Goal is the total amount you want to save.
- Monthly Income is your combined monthly income.
- Monthly Expenses is your combined monthly expenses.
- Timeframe is the number of years you have to reach your savings goal.
The formula accounts for your current savings rate and projects how much you need to invest each month to reach your goal.
Worked Example
Let's say a couple has:
- Combined monthly income of $8,000
- Combined monthly expenses of $5,000
- Savings goal of $100,000
- Timeframe of 10 years
Using the formula:
Calculation
Monthly Investment = ($100,000 - ($8,000 - $5,000) × 10) / (10 × 12)
Monthly Investment = ($100,000 - $30,000) / 120
Monthly Investment = $70,000 / 120 = $583.33
This means the couple needs to invest approximately $583.33 each month to reach their $100,000 savings goal in 10 years.
Interpreting Results
The results from the calculator provide several key pieces of information:
- Monthly Investment Needed: The amount you need to invest each month to reach your savings goal.
- Current Savings Rate: Your current monthly savings based on your income and expenses.
- Projected Savings: The total amount you will have saved by the end of the timeframe if you maintain your current savings rate.
Use these results to adjust your financial plan as needed. If the monthly investment amount seems too high or too low, consider adjusting your savings goal or timeframe.
