📈 复合增长Compound Growth

使用说明与常见问题How-to & FAQ

「复合增长」是什么？What is the Compound Growth tool?

终值 = 初值 × (1+r)^n。本地处理。可设置「初值」、「每期增长率 %」、「期数」。Final = start × (1+r)^n. Processed locally. Settings: Start, Rate % per period, Periods.

如何使用「复合增长」？How do I use the Compound Growth tool?

在「复合增长」中，填写「初值」、「每期增长率 %」、「期数」等参数，结果会随输入实时计算并显示在下方。In the Compound Growth: Fill in "Start", "Rate % per period", "Periods"; results are recalculated instantly as you type.

能用连续复利吗？Can it use continuous growth?

本页按离散复利计算：终值 = 初值 × (1 + r)ⁿ。连续增长为 初值 × e^(r·n)，在相同 r 下结果稍大。It uses discrete compounding: final = start × (1 + r)ⁿ. Continuous growth is start × e^(r·n), slightly larger for the same r.

能举个计算实例吗？Can you show a worked example?

例如在「复合增长」中填 初值 = 1000，每期增长率 % = 7，期数 = 10，结果区显示：终值：1,967.15；总增长：967.15For example, entering Start = 1000, Rate % per period = 7, Periods = 10 in the Compound Growth gives: Final: 1,967.15; Total growth: 967.15

哪些输入会被检查？Which inputs are validated?

「复合增长」会检查这些输入——「初值」：必须填写，须大于 0；「每期增长率 %」：必须填写；「期数」：必须填写，不能为负数，须为整数；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Compound Growth checks its inputs — "Start": required, must be greater than 0; "Rate % per period": required; "Periods": required, cannot be negative, must be a whole number; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.

有哪些选项可以调整？What options can I adjust?

「复合增长」的设置：「初值」默认 1000；「每期增长率 %」默认 7；「期数」默认 10。每次生成结果都按当前设置处理。Settings in the Compound Growth — "Start" default 1000; "Rate % per period" default 7; "Periods" default 10. The result always uses the current settings.

计算结果可以作为最终依据吗？Can I rely on the result?

「复合增长」按标准公式计算，结果仅供参考；实际金额以银行、券商或税务机关的规则和四舍五入方式为准。The Compound Growth uses standard formulas and is for estimation only; actual figures depend on your bank, broker or tax authority's rules and rounding.
