How to Use the Savings Timeline Calculator

The Savings Timeline Calculator allows you to estimate the time required to reach a specific savings goal. You will need to input the following parameters:

  1. Initial Savings: The amount of money you currently have saved.
  2. Target Amount: The total amount you wish to save.
  3. Monthly Contribution: The amount you plan to add to your savings each month.
  4. Interest Rate: The annual interest rate you expect to earn on your savings.
  5. Compounding Frequency: How often the interest is applied to your savings (e.g., annually, quarterly, monthly, or daily).

Formula Used in the Calculator

The calculator uses the following formula to determine how long it will take to reach your target savings amount:

Future Value of Savings Formula:

§§ FV = P \times (1 + r/n)^{nt} + PMT \times \left(\frac{(1 + r/n)^{nt} - 1}{r/n}\right) §§

Where:

  • § FV § — future value of the savings (target amount)
  • § P § — initial savings (present value)
  • § PMT § — monthly contribution
  • § r § — annual interest rate (as a decimal)
  • § n § — number of times interest is compounded per year
  • § t § — number of years

The calculator iteratively calculates the future value until it meets or exceeds the target amount, counting the number of months required.

Example

Let’s say you have the following inputs:

  • Initial Savings (P): $1,000
  • Target Amount (FV): $5,000
  • Monthly Contribution (PMT): $200
  • Interest Rate (r): 5% (0.05 as a decimal)
  • Compounding Frequency (n): Monthly (12 times a year)

Using the formula, the calculator will determine that it will take approximately 22 months to reach your target amount of $5,000.
