子女教育金计算器 Education Fund Calculator

考虑通胀(Inflation)与收益率(Return),估算未来教育资金需求,并给出每月/每年建议储蓄额。
Estimate your child’s future education funding needs with inflation and investment return, and see suggested monthly/annual savings.

仅影响显示格式,不改变计算逻辑。
This only changes display format, not the math.
以“今天”的价格估计一年总费用。后续将按通胀推算未来金额。
Estimate one-year total cost in today’s money. We’ll inflate it into future values.
从现在到“开始用教育金”的时间。比如孩子 8 岁、18 岁上大学 → 约 10 年。
Time from now until funding begins (e.g., 10 years until college).
资金支出将按“每年一笔”来近似模拟(可理解为每学年的预算)。
Spending is approximated as one withdrawal per year (a yearly budget model).
用于推算未来学费上涨(也可理解为教育成本的年增幅)。
Used to project rising education costs over time.
简化假设:从现在到未来、以及未来支出期间,资金都按同一收益率增长(现实中可更保守)。
Simplified: assumes a constant return before and during the spending years (you may use conservative inputs).
已经专门为教育准备、并计划继续投资的资金。会参与未来增长。
Current money earmarked for education, assumed to grow at the same return rate.
如果你已经有目标每月存款,工具会计算“未来够不够”与缺口。
If you already have a monthly plan, the tool checks whether it’s enough and shows shortfall/surplus.
3. 使用说明 · Notes 中英更详细版
  • 这不是“猜学费”,而是“把不确定性拆开” · This is not guessing tuition, it’s structuring uncertainty:
    现实里教育成本会受很多因素影响:学校选择、地区、汇率、住宿、补习、留学签证成本等。这个工具做的事情是把问题拆成两个关键变量:
    ① 通胀/成本增幅 (Inflation):未来每年的费用会不会比今天更贵?贵多少?
    ② 资金增长 (Return):你准备的教育金是否会在未来增长?增长多少?
    By separating inflation (cost growth) and return (money growth), you can run scenarios instead of relying on one “perfect” number.
  • 入学时需要准备多少?· Required Fund at Start:
    工具会先把“今天的一年教育费用”按通胀推算到入学时,再继续推算到第 2 年、第 3 年……直到持续年数结束。
    然后把这些未来支出按收益率折现回“入学时刻”,得到你在入学那一年开始时需要准备的总资金池(教育金本金)。
    We project each year’s cost forward with inflation, then discount those future withdrawals back to the enrollment start using the return rate.
  • 为什么“总名义支出”≠“入学时需要准备的钱”?· Why total nominal cost ≠ fund needed at start:
    因为“入学后那几年”,钱不一定躺着不动——如果教育金仍按收益率增长,那么后面几年的支出可以部分由收益覆盖。
    That’s why the required fund at start is often smaller than simply summing all nominal costs.
  • 建议每月存入的逻辑 · How monthly saving is calculated:
    工具把“你已有的教育金”先按收益率滚到入学时(Existing Savings → grows into the future),再计算为了达到入学时目标资金,还需要每月补多少(PMT)。
    若你填写了“计划每月存入”,工具会反算你入学时能攒到多少,并给出缺口/富余。
    If you enter a planned monthly contribution, the tool checks your future fund and shows shortfall or surplus.
  • 重要假设(务必读) · Key assumptions (please read):
    1) 费用按“每年一笔”估算(更像每学年预算),并默认在每年年末发生支出(折现模型更直观)。
    2) 收益率与通胀率为固定值(现实里会波动)。你可以用“偏保守”的收益率、偏高的通胀率做压力测试。
    3) 未包含税费、手续费、汇率波动、投资亏损年份、突发支出等。
    We assume yearly withdrawals, constant rates, and ignore taxes/fees/FX/market drawdowns. Use conservative rates for safer planning.
  • 如何用这个工具做“情景推演” · How to use it for scenario planning:
    ✅ 先做“基准场景”:通胀 3%,收益 5%~6%,看每月大致要存多少。
    ✅ 再做“保守场景”:通胀 4%~6%,收益 3%~4%,看压力测试下缺口多少。
    ✅ 最后做“激进场景”(仅用于了解上限):收益 7%~9%,对比你能减少多少月存压力。
    Run baseline → conservative → aggressive to understand the range, not a single answer.
  • 一个实用建议 · A practical tip:
    教育金的本质是“目标资金池”,越接近入学,越要把波动降下来(比如逐步降低高风险资产比例),避免在要用钱的年份遇到大回撤。
    As enrollment approaches, consider reducing volatility so the money is there when you need it.
