Formula Used

The calculator uses the following formula to calculate your remaining money:

Final Amount Formula

Final Amount = Initial Amount - (Monthly Expenses × Number of Months) + (Monthly Savings × Number of Months) + (Future Value of Investments)

Where Future Value of Investments is calculated using the compound interest formula:

Future Value = Monthly Investments × [(1 + r)ⁿ - 1] / r

Where r is the monthly interest rate (Annual Return / 12 / 100) and n is the number of months.

This formula accounts for your starting amount, ongoing expenses, savings, and the growth of your investments over time.

Worked Example

Let's look at an example to understand how the calculator works.

Example Scenario

Initial Amount: $5,000

Monthly Expenses: $1,000

Number of Months: 12

Monthly Savings: $500

Monthly Investments: $300

Annual Return: 5%

Using these values:

Total Expenses: $1,000 × 12 = $12,000
Total Savings: $500 × 12 = $6,000
Future Value of Investments: $300 × [(1 + 0.004167)¹² - 1] / 0.004167 ≈ $4,200
Final Amount: $5,000 - $12,000 + $6,000 + $4,200 = $3,200

So, after 12 months, you would have $3,200 left.
