评估投资项目的回报率，比较不同投资方案的效果
我们的投资回报计算器帮助您快速评估任何投资项目的收益表现。只需以下几个简单步骤：
该工具适用于股票、基金、房地产、定期存款等各类投资产品的收益评估与横向比较。
Our investment return calculator helps you quickly evaluate the performance of any investment. Follow these simple steps:
This tool is suitable for evaluating and comparing returns across stocks, funds, real estate, fixed deposits, and other investment products.
ROI 衡量投资的总收益相对于初始成本的百分比回报：
例如：ROI 为 60% 意味着每投入 1 元，您获得了 0.60 元的收益。
CAGR 将投资收益平摊到每一年，反映复合增长的真实速率：
其中 n 为投资年限。CAGR 消除了不同投资期限带来的比较偏差，是评估长期投资表现的核心指标。
ROI measures the percentage return of an investment relative to its initial cost:
For example, an ROI of 60% means you earned $0.60 in profit for every $1.00 invested.
CAGR smooths investment returns into an equivalent annual rate, reflecting the true pace of compound growth:
Where n is the number of years. CAGR eliminates bias from differing investment horizons and is the key metric for evaluating long-term investment performance.
场景：小王在 2020 年初投资了 ¥50,000 购买一只指数基金，到 2025 年初基金市值增长至 ¥80,000，投资期限为 5 年，期间无额外费用。
这意味着小王的投资在 5 年间以年均约 9.86% 的复合速率增长，总回报率达 60%。
Scenario: Jane invested $50,000 in an index fund at the beginning of 2020. By the beginning of 2025, the fund's market value grew to $80,000, over an investment period of 5 years, with no additional costs.
This means Jane's investment grew at a compound rate of approximately 9.86% per year, delivering a total return of 60% over the 5-year period.
投资回报率（ROI）是衡量投资盈利能力的核心指标，计算公式为（收益 ÷ 成本）× 100%。它能直观地展示投资的总体回报比例。但 ROI 的局限在于它不考虑投资时间跨度 — 两个 ROI 相同的投资，如果持有年限不同，实际表现差异可能很大。因此，我们建议结合年化收益率（CAGR）一起分析。
判断投资回报好坏需要参照比较基准。一般来说，年化收益率超过同期无风险利率（如国债收益率或银行定期存款利率）即可视为正回报。历史上，股票市场长期年化回报约为 7%–10%。您可以使用本计算器对比不同投资方案的 CAGR，选择风险调整后收益更优的方案。
CAGR（复合年化增长率）就是年化收益率的一种计算方式，它假设收益每年以相同速率复合增长。与简单年化收益率（总收益 ÷ 年数）不同，CAGR 考虑了复利效应，更准确地反映了投资的真实增长轨迹。对于超过一年的投资，CAGR 是更科学的评估指标。
比较不同投资时，请分别输入每个方案的初始金额、期末价值和投资年限，然后重点对比"年化收益率（CAGR）"这一指标。CAGR 消除了投资金额和期限差异带来的影响，让您可以在同一标准下评估各方案的效率。同时别忘了考虑额外成本 — 高回报但费用也高的投资，净收益未必最优。
Return on Investment (ROI) is a core metric for measuring investment profitability, calculated as (Gain ÷ Cost) × 100%. It provides an intuitive picture of overall return percentage. However, ROI's limitation is that it does not account for the time horizon — two investments with the same ROI can perform very differently if held for different durations. We recommend analyzing ROI alongside the Compound Annual Growth Rate (CAGR) for a complete picture.
Judging whether a return is good requires a benchmark. Generally, an annualized return exceeding the risk-free rate of the same period (such as government bond yields or fixed deposit rates) counts as a positive real return. Historically, the stock market has delivered long-term annualized returns of roughly 7%–10%. Use this calculator to compare the CAGR of different investment options and choose the one with the better risk-adjusted return.
CAGR (Compound Annual Growth Rate) is a method of calculating annualized return that assumes profits grow at a constant compounded rate each year. Unlike simple annualized return (total gain ÷ number of years), CAGR accounts for the compounding effect, more accurately reflecting the true growth trajectory of an investment. For investments held longer than one year, CAGR is the more rigorous evaluation metric.
When comparing investments, enter each option's initial amount, ending value, and holding period separately, then focus on comparing the "Annualized Return (CAGR)" figure. CAGR eliminates the distortion caused by different investment amounts and time horizons, letting you evaluate each option on an equal footing. Also remember to factor in additional costs — a high-return investment with hefty fees may not yield the best net profit.
