How to Use This Calculator
Enter the amount you invested (your upfront or ongoing cost) and the final value or total proceeds before subtracting the investment amount (not net profit). The ROI calculator instantly shows you the return on investment as a percentage, along with total profit, annualized return, and a visual breakdown of principal versus profit.
Use this tool to evaluate real business decisions such as marketing campaigns, equipment purchases, software subscriptions, hiring decisions, inventory investments, or any expense where you expect a measurable financial return. The calculator works for one-time investments as well as recurring costs that generate ongoing returns.
For a total-project marketing example, $9,000 gross revenue minus $3,000 fulfillment and $3,000 advertising leaves $3,000 profit on $6,000 total cost: 50% ROI. Enter Investment Amount $6,000 and Final Value $9,000. Gross revenue is not net profit.
For multi-year investments, be sure to enter the holding period in the time field so the calculator can compute the annualized ROI — this is essential for fairly comparing a 2-year equipment lease against a 5-year real estate investment or a 1-year marketing campaign.
Worked example
Example 1 — Google Ads campaign for a contractor: $9,000 gross revenue, $3,000 fulfillment costs, and $3,000 ads give $6,000 total cost and $3,000 gain: ($9,000 - $6,000) / $6,000 = 50% total-project ROI. Alternatively, return on ad investment uses $6,000 contribution before ads and $3,000 ad cost: ($6,000 - $3,000) / $3,000 = 100%. These use different cost scopes; do not subtract fulfillment twice or call revenue net profit.
Example 2 — Equipment purchase: An $8,000 truck produces an assumed $12,000 annual cash benefit net of operating costs, excluding residual sale value, financing, and tax effects. First-year simple ROI is ($12,000 - $8,000) / $8,000 = 50%. Five years of benefits total $60,000, giving 650% simple ROI. Treating that $60,000 as a single end-of-year-five terminal value gives 49.6278% CAGR. Actual annual cash receipts have different timing: this terminal-value illustration is not a money-weighted IRR.
Example 3 — Stock market investment: An investor buys $10,000 worth of an index fund and sells 3 years later for $13,500. The simple ROI is ($13,500 - $10,000) / $10,000 = 35%. The annualized return, accounting for the 3-year holding period, is (($13,500 / $10,000)^(1/3) - 1) x 100 = about 10.5% per year. This makes it easy to compare against other investment options regardless of their time horizon.
Annualized ROI and CAGR: the formula and worked examples
Annualized ROI converts a multi-year return into a single per-year rate so different investments can be compared on equal footing. The formula — also known as CAGR (compound annual growth rate) — is: Annualized ROI = ((Final Value / Investment Amount)^(1 / Years) - 1) x 100. The exponent (1 / Years) is what makes this a compound, not a simple, average: gains in later years build on earlier ones.
Worked example — 3-year hold: An investment grows from $10,000 to $13,500 over 3 years. Simple ROI is 35%, but annualized: (13,500 / 10,000)^(1/3) = 1.1049, so annualized ROI is about 10.5% per year. That is the number to compare against a savings account, bond, or another 3-year opportunity.
Worked example — 5-year hold: A project returns $76,000 on a $50,000 investment after 5 years (a separate illustration; the default period is 3 years). Simple ROI is 52%; annualized: (76,000 / 50,000)^(1/5) = 1.0872, or about 8.7% per year. Same investment, two honest numbers: use the annualized figure whenever the holding periods differ between options.
Quick reference — 100% total ROI annualized: 1 year = 100%/yr; 2 years = 41.4%/yr; 3 years = 26.0%/yr; 5 years = 14.9%/yr; 10 years = 7.2%/yr. Doubling your money takes longer to look impressive once it is annualized — which is exactly why lenders, VCs, and analysts quote CAGR rather than total return for multi-year investments.

Methodology and sources
The standard ROI formula used by this calculator is: ROI = (Final Value - Cost) / Cost x 100. This is the most widely accepted definition of return on investment and is used across finance, business analysis, and marketing measurement worldwide.
For the annualized ROI calculation, we use the compound annual growth rate (CAGR) formula: Annualized ROI = ((Final Value / Investment Amount)^(1 / Years) - 1) x 100. This accounts for the time value of money by assuming returns compound over the holding period, giving a more accurate picture for multi-year investments.
Limitations of simple ROI: The basic ROI calculation does not account for the time value of money, inflation, risk, or the timing of cash flows. Two investments with the same total ROI may have vastly different risk profiles or cash flow patterns. For this reason, we recommend using annualized ROI alongside the simple figure, especially for investments spanning multiple years.
Limitations of annualized ROI: The CAGR formula assumes steady, compounding growth every year, which rarely matches reality. Actual returns fluctuate year to year. CAGR is a useful simplification, not a precise prediction. Always review the underlying cash flows when evaluating any real investment.

How people actually search for ROI calculators
People search for ROI calculators in many different ways, and this page is built to answer the most common ones directly. If you arrived here searching for any of the phrases below, you are in the right place.
- "annual ROI" or "annual ROI formula" — this page shows both the simple total ROI and the annualized (compound) ROI side by side, with the full formula explained in the methodology section above.
- "annualised ROI" or "annualized ROI calculator" — the British and American spellings both work; the calculator accepts any positive number of years and produces an annualized figure automatically.
- "calculate my return on investment" or "how to figure out ROI" — enter your investment amount, your final value, and the holding period; the calculator does the rest and shows the math.
- "calculating ROI" or "calculator ROI" — the worked examples above walk through the calculation step by step for a Google Ads campaign, an equipment purchase, and a stock market investment.
- "percentage return on investment" or "calculate percentage of return" — the primary output is a percentage, with the underlying dollar profit also shown so you can verify the math yourself.
- "return on investment calculators" or "investment ROI calculator" — this page is a free investment ROI calculator that covers one-time investments, recurring costs, marketing campaigns, equipment purchases, and stock market holds.
- "ROI calculater" (common misspelling) — yes, the math is the same; the formula is (final value - investment amount) / investment amount, multiplied by 100.
- "ROI calculator for monthly investment" — enter the total invested as your investment amount, the ending portfolio value as your final value, and the holding period in years (a 24-month SIP becomes 2 years).
Common mistakes to avoid
- Ignoring time period: A 100% ROI over 1 year is dramatically different from a 100% ROI over 5 years. Always annualize returns to compare different investments on a level playing field. Our calculator includes an annualized ROI metric for exactly this purpose.
- Forgetting ongoing and hidden costs: The initial purchase price is rarely the total cost. A piece of equipment may require maintenance, training, insurance, software licenses, installation, and operational costs that add 20-50% to the true investment. Factor all of these into the investment amount for an accurate ROI calculation.
- Attribution errors: Did that sales increase come from your marketing campaign or from seasonal demand, a competitor going out of business, or a broader market trend? Use A/B testing, control periods, or statistical methods to isolate the actual effect of your investment. Over-attributing results inflates ROI and leads to poor decisions.
- Only measuring financial returns: Not all value shows up on a balance sheet. Investments in employee training, brand building, customer satisfaction, cybersecurity, and workplace safety have real but hard-to-quantify benefits. Consider these qualitatively even if the calculated ROI looks low or negative.
- Confusing ROI with profit margin: A 50% profit margin on a product is not the same as a 50% ROI on your business investment. ROI compares total return to total cost, whereas margin is return relative to revenue. They measure fundamentally different things and should not be used interchangeably.
- Not considering opportunity cost: If you invest $50,000 in project A and earn 8% annually, but you could have earned 12% in a different investment with similar risk, the real cost of choosing project A is the 4% gap. Always ask: what else could this money be doing?
Frequently asked questions
What is a good ROI?
A common back-of-envelope benchmark treats 50-200% first-year ROI as strong for many small-business investments (heuristic, not a target). Some marketing teams set aspirational ROI targets — illustrations exist at hundreds of percent; model the return your own project needs instead of using a market target. Investor.gov notes that some experts use roughly 7-10% as a historical planning estimate for long-term diversified U.S. stock investing. Investments have no set return, and this is not a forecast or guarantee. The definition of a good ROI depends entirely on your industry, risk tolerance, and cost of capital. A safe rule: any ROI above your weighted average cost of capital (WACC) is generating value.
How do I calculate ROI over multiple years?
For multi-year investments, first identify total proceeds over the full period and subtract total cost once; do not enter net profit as Final Value. Divide profit by cost and multiply by 100 to get total ROI percentage. To compare different time periods fairly, use the annualized ROI formula built into this calculator: ((final value / investment amount)^(1/years) - 1) x 100. For a single terminal value, a 44% total return over 5 years annualizes to about 7.6% per year. Periodic cash flows require a timing-aware measure such as IRR.
What if my investment has no direct monetary return?
Not all value is financial. Investments in employee training, customer satisfaction programs, brand awareness campaigns, cybersecurity upgrades, and workplace safety improvements often have indirect or long-term returns that are difficult to quantify in dollar terms. For these, consider using a balanced scorecard approach or multi-factor decision framework that incorporates qualitative benefits alongside the financial ROI calculation. Our calculator gives you the financial picture, but you should weigh non-monetary factors separately.
Is a negative ROI always bad?
Not necessarily. Strategic investments like research and development, employee training, brand building, and market entry often show negative ROI in the short term but create significant long-term value. Amazon famously operated at negative ROI for years while building its infrastructure and market share. The key is to have a clear thesis for when and how the investment will eventually turn positive. If there is no plausible path to positive returns, a negative ROI likely signals a poor decision.
What is the difference between ROI and annualized ROI?
Simple ROI measures total return over the entire investment period without any adjustment for time. Annualized ROI converts that total return into a per-year rate assuming compound growth. This is essential for comparing investments with different durations. For example, a 100% ROI over 5 years is impressive in total but only works out to about 14.9% per year annualized. The same 100% ROI over 1 year is a phenomenal 100% annualized. Always use annualized ROI when comparing opportunities with different time horizons.
How do I calculate ROI for a rental property?
For rental property ROI, your investment includes the down payment, closing costs, renovation expenses, and ongoing costs like property management, insurance, taxes, and maintenance. Your return includes rental income plus any property appreciation when you sell. A common metric is the cash-on-cash return: annual pre-tax cash flow divided by total cash invested. Many real estate investors use 8-12% cash-on-cash as a common screening range (heuristic, not a rule). This calculator handles the basic ROI framework; for real estate specifically, also consider For real estate specifically, also consider cap rate, IRR, and cash flow analysis.
What is the annualized ROI (CAGR) formula?
Annualized ROI uses the compound annual growth rate formula: ((final value / investment amount)^(1/years) - 1) x 100. For example, $10,000 growing to $13,500 over 3 years is (1.35)^(1/3) - 1 = 10.5% per year. Use the annualized figure whenever you compare investments with different holding periods, because a 35% total return means very different things at 1 year versus 10 years.
