什么是 529 大学储蓄计划？
529 计划是一种专为教育支出设计的税收优惠投资账户。供款可享受免税增长，且用于符合条件的教育费用时，取款也免税，例如学费、食宿、书本和杂费。许多州还为供款提供州所得税抵扣或税收抵免，因此 529 计划是为孩子未来教育储蓄的高效方式之一。与普通券商账户不同，免税增长在大多数家庭用于储蓄的 10 到 18 年里会形成显著的复利效应。

这个计算器如何工作
该工具会按照你预期的年回报率，用复利增长来预测当前 529 余额的未来价值，然后计算你每月需要储蓄多少，才能弥补与大学总费用目标之间的差额。它使用标准的年金终值公式：供款按你的预期利率按月复利，直到孩子达到目标年龄；所需月供则通过代数求解，从而让账户正好按计划达到目标。
03
为什么尽早开始很重要
大学储蓄中最重要的杠杆是时间，而不是供款金额。孩子 3 岁时存入的 1 美元有 15 年的复利时间，而 13 岁时才存入的 1 美元只有 5 年。由于复利效应，哪怕晚 5 年开始，达到同一目标所需的每月供款也可能几乎翻倍。使用下方的逐年表格，可以看到随着投资增长超过新增供款，后期余额会加速增长。
04
如何选择预期回报率
大多数 529 计划都提供按年龄配置的投资组合：孩子年幼时更激进（股票占比更高），临近大学时逐步转向保守（债券和现金占比更高）。对于分散配置的按年龄投资组合，5% 至 7% 的平均年回报率是一个合理的长期规划假设，不过实际回报会逐年波动，市场表现也从不保证。你也可以用更低的回报率（例如 4%）再算一次，看看更保守情况下所需的供款。
05
哪些支出属于合格的 529 支出
合格支出包括学费和杂费、食宿（若至少半日制注册）、必需的书本和学习用品，以及主要用于课业的电脑。每年最多还可用于 K-12 学费的 10,000 美元，以及终身最多 10,000 美元的学生贷款偿还。非合格取款的收益部分需缴纳所得税，并加收 10% 罚金，因此与其超额储蓄，不如更现实地规划目标供款金额。
06
随时间调整你的计划
在储蓄的这些年里，大学费用、投资回报和家庭财务状况都会变化。建议每年重新查看一次这个计算器，更新当前储蓄余额和剩余年数，以保持所需月供的准确性。如果市场下跌导致余额缩水，计算器会显示未来需要更高的供款；如果某一年市场表现强劲，你也许可以减少供款。把 529 规划与更广泛的家庭预算工具结合起来，比如我们的贷款计算器或房贷计算器，可以帮助你看到完整的财务状况。

州税优惠与计划选择
Over 30 states offer a state income tax deduction or credit for 529 contributions, but you're not required to use your own state's plan — you can shop for the lowest fees and best investment options nationwide, though you may give up the state tax break by doing so. Compare expense ratios, historical performance of age-based portfolios, and any state-specific match programs before choosing a plan, since fees compound negatively the same way returns compound positively.
常见问题
How much should I have saved for college by my child's age?
A common rule of thumb is to have roughly one year of projected college costs saved by the time your child starts high school, but the right number depends on your total goal, whether you're targeting public or private school costs, and how many years remain. Use this calculator with your specific goal amount for a personalized target.
What if I can't afford the required monthly contribution?
Save what you can consistently rather than nothing at all. Even partial funding significantly reduces future student loan burden, and you can combine 529 savings with financial aid, scholarships, and student loans to cover the rest. Revisit the calculator periodically as your income grows.
Can I use a 529 plan for any college?
Yes. 529 funds can be used at any accredited college, university, or vocational school in the U.S. and many international institutions, regardless of which state's 529 plan you use.
What happens to unused 529 funds?
You can change the beneficiary to another family member, use up to $35,000 to fund a Roth IRA for the beneficiary (subject to conditions), or withdraw the funds and pay income tax plus a 10% penalty on the earnings portion only.
Does this calculator account for financial aid or scholarships?
No. This tool only projects savings growth toward your stated cost goal; it does not factor in expected financial aid, scholarships, or student loans, which can meaningfully reduce your actual out-of-pocket need.
Is this calculator financial advice?
No. This tool provides estimates for educational purposes only and is not financial, tax, or investment advice. Investment returns are never guaranteed. Consult a qualified financial advisor or tax professional for guidance specific to your situation.
