Como calcular o ROI?
ROI (Return on Investment) é o ganho percentual de um investimento. A fórmula é:
ROI = (Ganho - Investimento) / Investimento × 100.
O ROI anualizado normaliza o retorno por ano, permitindo comparar investimentos com prazos diferentes:
ROI_anual = ((Final / Inicial)^(1/anos) - 1) × 100.
Esse cálculo equivale ao CAGR e é o número certo para comparar fundos, ações ou imóveis com horizontes diferentes.

ROI: Return on Investment
ROI (Return on Investment) measures the profitability of an investment as ROI = (gain − cost) / cost · 100%. It's a simple, time-agnostic ratio: invest R$ 10,000 and get back R$ 15,000 means a 50% ROI. The main limitation is precisely that it ignores time — two projects with the same 50% ROI but durations of 1 year vs 5 years are not equivalent. For time-sensitive comparisons, use CAGR (Compound Annual Growth Rate) or IRR (Internal Rate of Return) instead. Common variants include ROAS (Return on Ad Spend) in digital marketing, ROE (Return on Equity) for shareholders, and ROIC (Return on Invested Capital) for operating performance.
Applications and context
ROI is the default metric for evaluating marketing campaigns (Google Ads, Meta Ads — typically measured as ROAS), M&A decisions, internal projects, and real estate investments (rental yield plus appreciation). It's useful for quick screening, but pair it with payback period and CAGR whenever horizon matters.
Calculate your return on investment (ROI)
Did the investment actually pay off? A lot of that answer fits into one metric: ROI, return on investment. This calculator weighs what you put in against what you got out and gives the result as a percentage, so it's clear whether the money really worked for you.
Besides the percentage ROI, it shows net profit and annualised ROI, which is the figure that lets you compare investments of different lengths without skewing things. It works for sizing up a financial application as much as for gauging the return on a marketing campaign, a course or any outlay you hope will pay back.
None of your numbers are saved anywhere; the math runs in the browser the moment you type. Tweak the values, run a few scenarios, and get a feel for the return before or after you invest.

Modigliani M² Measure
Computes Modigliani's M² measure (also M-squared or RAP), which translates the Sharpe ratio back into percentage points of return. The idea is plain: scale the portfolio to the market's volatility and ask what it would have returned under those conditions, M² = Rf + (Rp − Rf)·(σmarket/σportfolio). Unlike the Sharpe ratio, a bare number, M² compares directly against the benchmark's return. Above the market return, the portfolio beat the benchmark on a risk-adjusted basis. Enter the portfolio return and volatility, the risk-free rate and the market volatility.

Burke Ratio
Computes the Burke ratio: the excess return over the risk-free rate divided by the square root of the sum of squared drawdowns. Unlike the Sharpe ratio, which penalizes all volatility, Burke focuses only on the falls, and by squaring each drawdown it punishes deep falls more than shallow ones. It's one of the tail-risk-adjusted performance metrics. Enter the portfolio return, the risk-free rate and the list of drawdowns in percent.
Residual Income
Computes a company's residual income: net income minus a charge for the use of equity capital, equal to the capital times the required cost of capital. The idea is that accounting profit doesn't tell the whole story — value is only created when earnings exceed what shareholders could earn elsewhere at the same risk. A positive residual income signals a return above the cost of capital. Enter the net income, the equity capital and the cost of equity.
Volatility Drag (Variance Drag)
Computes volatility drag: the loss of the compound (geometric) return relative to the average (arithmetic) return, approximately volatility squared divided by two. It's the reason a portfolio that does +50% and then −50% doesn't return to the start: volatility erodes compound growth. The more volatile the asset, the larger the drag, even with the same average return. Enter the arithmetic mean return and the volatility.
