Education Savings Calculator

Project the future wealth of an education savings fund based on an initial deposit, monthly recurring contributions, and compound investment growth.

Calculation Results

Future Value of Savings Formula

Future Value = [Initial Deposit × (1 + r)^n] + [Monthly Deposit × (((1 + r)^n − 1) / r)]
  • Calculates combined compound growth on both initial lump sum and monthly dollar-cost averaging.
  • Breaks down principal deposits versus passive compound interest earnings.
  • Visualizes the hockey-stick acceleration of investment growth over 10+ year time horizons.
  • Adaptable for K-12 private school funds, college accounts, and vocational training savings.

Step-by-Step Worked Example

Scenario: Family starting with $5,000 and contributing $250/month for 10 years at a 7% average return.

Calculation Steps:

  1. Growth on Initial $5,000: $5,000 × (1 + 0.07/12)^120 = $10,048.
  2. Growth on Monthly $250 Series: $250 × [((1.005833)^120 − 1) / 0.005833] = $43,023.
  3. Total Future Account Value: $10,048 + $43,023 = $53,071.
  4. Total Principal Deposited: $5,000 + ($250 × 120) = $35,000.
  5. Total Compound Earnings: $53,071 − $35,000 = $18,071 (34% of final balance).
Result: After 10 years, your education fund grows to $53,071. You deposited $35,000 in principal and earned $18,071 in compound interest.

  • Taxes on earnings depend on account type (taxable brokerage vs. tax-exempt 529 plan).

Frequently Asked Questions

Should I use a 529 plan or a taxable brokerage account for college?

A 529 plan offers 100% tax-free growth and tax-free withdrawals for qualified educational expenses. A taxable account offers more flexibility for non-education expenses but requires paying capital gains taxes on earnings.
