How the Estimator Works

This calculator estimates the future value of your 529 savings based on four key inputs:

  • Initial lump-sum contribution
  • Monthly contributions
  • Expected annual rate of return
  • Number of years to save

Compound Growth Formula

We assume monthly contributions with monthly compounding.

FV = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) - 1) / (r/n)]

Where:

  • P = Initial contribution
  • PMT = Monthly contribution
  • r = Annual rate of return (decimal)
  • n = Compounding periods per year (12)
  • t = Years invested

Case Studies

  • Initial Contribution: $2,000
  • Monthly Contribution: $150
  • Years: 18
  • Rate of Return: 6%

Estimated Balance: $66,524.77

FV ≈ 2,000*(1 + 0.06/12)^(12*18) + 150*[((1 + 0.06/12)^(12*18) - 1) / (0.06/12)]

David's Late Start

  • Initial Contribution: $0
  • Monthly Contribution: $400
  • Years: 5
  • Rate of Return: 5%

Estimated Balance: $27,125.40

FV ≈ 0 + 400*[((1 + 0.05/12)^(12*5) - 1) / (0.05/12)]

Frequently Asked Questions

A tax-advantaged savings plan to help families save for education expenses.

A higher rate of return can significantly increase your savings over time due to compound interest.

The calculator assumes consistent contributions. Skipping months will lower your total savings—use a spreadsheet or adjust the average monthly input to reflect this.

Yes. If you only have a lump-sum contribution, enter that and set monthly contributions to zero.

The calculator supports negative returns to model down markets. This will reduce your estimated balance and reflect potential loss scenarios.

No, the model assumes gross returns and does not deduct management fees or adjust for inflation. Consider reducing the rate of return to estimate net outcomes.

Yes, 529 plans now allow withdrawals for up to $10,000 annually for K–12 tuition. Adjust your saving horizon accordingly.

That depends on your college cost target, saving timeline, and expected returns. Use this calculator to test different contribution scenarios.
