How it works

The College Savings Strategy Planner helps you determine how long it will take to reach your college savings goal for your child. By inputting your child's current age, the target amount you wish to save, your monthly contributions, the expected annual return rate, and your tax rate, the calculator uses a logarithmic formula to estimate the time required to achieve your savings goal. For example, if your child is currently 3 years old, you aim to save $100,000, contribute $400 monthly, expect a 7% return, and have a tax rate of 22%, the calculation will show you how many months it will take to reach your target. Using the formula, you can find that it will take approximately 15 years, or 180 months, to accumulate the target amount. Additionally, the tool calculates the potential tax-free growth in a 529 plan, allowing you to see how much of your investment can grow without being taxed, maximizing your savings potential.

Formula


                Months to target = ln(target / (monthly × rate)) ÷ ln(1 + rate). 529 tax benefit = Growth × Tax rate.
              

Tips

  • Start saving early: The earlier you begin, the more time your money has to grow through compound interest.
  • Consider a 529 plan: These plans offer tax advantages and can significantly boost your college savings.
  • Review your investment options: Diversify your investments to balance risk and return based on your time horizon.
  • Adjust contributions as needed: Regularly assess your financial situation and adjust your monthly contributions to stay on track.
