Calculation Results

Required Monthly Savings Annuity Formula

Monthly Contribution = Remaining Goal Needed / [((1 + r)^n − 1) / r], where r = Annual Return / 12 and n = Months Until College
  • Compounds existing savings balance over the remaining investment horizon.
  • Calculates the net savings gap after growth of your starting nest egg.
  • Determines the exact monthly deposit needed to reach 100% of your college target.
  • Illustrates the dramatic benefit of starting early: compound earnings cover a large share of the goal.

Step-by-Step Worked Example

Scenario: Parents of a 5-year-old wanting to save $90,000 by age 18 with a $10,000 starting balance and 6.5% return.

Calculation Steps:

  1. Time Horizon: 18 − 5 = 13 years (156 months).
  2. Future Value of $10,000 Starting Balance: $10,000 × (1.005417)^156 = $23,205.
  3. Remaining Goal Needed from Contributions: $90,000 − $23,205 = $66,795.
  4. Required Monthly Contribution: $66,795 / [((1.005417)^156 − 1) / 0.005417] = $274.60 per month.
  5. Total Family Out-of-Pocket Deposits: $10,000 + ($274.60 × 156) = $52,838.
  6. Compound Investment Earnings: $90,000 − $52,838 = $37,162 generated by growth.
Result: Save $274.60 per month for 13 years to hit your $90,000 goal. Compound interest contributes $37,162 (41.3%) toward the total target.
