How This Calculator Works
Return on investment (ROI) measures how much an investment gained or lost, as a percentage
of what you originally put in. Enter what you invested and what it’s worth now (or what you
sold it for), and this calculator shows your total percentage return, your net profit in
dollars, and — if you enter how long you held it — that same return expressed as a yearly
rate, so investments held for different lengths of time can be compared fairly.
This is deliberately the simple, single-investment version: it assumes one lump sum in and
one lump sum out. The Compound Interest Calculator instead projects a balance forward
under an assumed growth rate, and a full multi-cash-flow analysis (money going in and out at
different times) needs a more involved tool than this one.
The steady yearly rate that would turn your initial investment into the final value over exactly
that many months, letting you compare a 6-month investment against a 3-year one on equal footing.
Worked Example
Investing $10,000, now worth $15,000, held for 36 months (3 years):
Net Profit: 15,000−10,000=5,000 dollars.
ROI: 5,000÷10,000×100=50%.
Annualized ROI: (15,000÷10,000)12÷36−1≈14.47% per year.
A 50% total return sounds identical whether it took 6 months or 6 years — the annualized
figure is what actually lets you compare the two.
Cómo funciona esta calculadora
El retorno de la inversión (ROI) mide cuánto ganó o perdió una inversión, como porcentaje de lo
que originalmente invertiste. Ingresa lo que invertiste y lo que vale ahora (o por lo que lo
vendiste), y esta calculadora muestra tu retorno porcentual total, tu ganancia neta en dólares y —
si indicas cuánto tiempo lo mantuviste — ese mismo retorno expresado como una tasa anual, para que
puedas comparar de forma justa inversiones mantenidas durante distintos períodos de tiempo.
Esta es deliberadamente la versión simple, de una sola inversión: asume un único monto que entra y
un único monto que sale. La Compound Interest Calculator en cambio proyecta un saldo
hacia adelante bajo una tasa de crecimiento asumida, y un análisis completo de múltiples flujos
de efectivo (dinero que entra y sale en distintos momentos) necesita una herramienta más
elaborada que esta.
La tasa anual constante que convertiría tu inversión inicial en el valor final a lo largo de
exactamente esa cantidad de meses, permitiéndote comparar en igualdad de condiciones una inversión
de 6 meses con una de 3 años.
Ejemplo resuelto
Invirtiendo $10,000, que ahora vale $15,000, mantenidos durante 36 meses (3 años):
Ganancia neta: 15,000−10,000=5,000 dólares.
ROI: 5,000÷10,000×100=50%.
ROI anualizado: (15,000÷10,000)12÷36−1≈14.47% por año.
Un retorno total del 50% suena idéntico ya sea que haya tomado 6 meses o 6 años — la cifra
anualizada es lo que realmente te permite comparar ambos casos.
It depends heavily on the investment type, risk level, and time horizon — there's no single universal benchmark. A savings account and a small business venture have very different reasonable ROI expectations. Comparing an investment's annualized ROI against a relevant benchmark (like a broad stock market index over the same period) is usually more meaningful than judging the raw percentage alone.
Why does the annualized return differ so much from the total ROI?
Total ROI is the whole-period return with no regard for how long it took. Annualized ROI (CAGR) spreads that same return evenly across each year, compounding — so a 50% return over just 6 months annualizes to a much higher rate than a 50% return over 6 years, even though the total dollar profit could be identical.
Does this account for fees, taxes, or dividends?
No — this calculator compares a starting value to an ending value directly. If you received dividends or other income along the way, add that to the final value first. Fees and taxes reduce your real-world return but aren't subtracted automatically here, since they vary widely by account type and situation.
