529 Calculator

Finance

This 529 plan calculator estimates how much an education savings fund could grow before a child starts college. Enter your annual contribution, an expected annual return, and the number of years until college, and it projects the fund's value using the future value of an annuity.

Formula

FV = PMT × [((1 + r)ⁿ - 1) / r]
  • The fund is projected with the future value of an ordinary annuity: FV = PMT × [((1 + r)ⁿ − 1) / r].
  • PMT is your annual contribution, r the annual return as a decimal, and n the number of years until college.
  • Starting earlier gives compounding more time to work, which is why small early contributions can outweigh larger late ones.
  • Enter the return as a plain percentage (e.g. 8 for 8%) and amounts in your local currency.
  • This is a simplified estimate assuming a constant return and level contributions; it ignores fees, taxes, and tuition inflation.

Example Calculation

Inputs
  • Annual Contribution (PKR): 50000
  • Annual Return %: 8
  • Years Until College: 18

Saving PKR 50,000 a year for 18 years at an 8% return projects an education fund of about PKR 1.87 million by the time college begins.

Frequently asked questions

What is a 529 plan?
It is a tax-advantaged savings plan designed to help families set money aside for future education costs, with earnings that can grow tax-free when used for qualified education expenses.
How is the projected fund calculated?
Using the future value of an annuity, FV = PMT × [((1 + r)ⁿ − 1) / r], assuming you contribute the same amount each year at a constant return.
Why start saving early?
The earlier you start, the more years compounding has to grow the balance, so early contributions typically contribute far more to the final fund than later ones.
What return should I assume?
Age-based 529 portfolios often start aggressive and grow conservative. A long horizon might assume around 7-8%, decreasing as college nears.
Does it account for tuition inflation?
No. It projects the savings side only. Because tuition tends to rise faster than general inflation, you may want to target a fund larger than today's costs.
