Key takeaways
- Calculate ROI using the formula (Net Profit ÷ Cost of Investment) × 100 to measure whether your business spending — from marketing campaigns to equipment purchases — is generating worthwhile returns.
- Target an ROI of 10–15% or higher as a general benchmark, but adjust your expectations based on your industry, the risk level involved, and how long the investment takes to pay off.
- Recognise that ROI doesn't account for time, hidden costs, or qualitative benefits like brand reputation, so pair it with other metrics such as payback period and risk assessment for a fuller picture.
- Apply ROI analysis before committing funds to compare options objectively, justify spending decisions, and focus your resources on what actually delivers results for your business.
Key takeaways

- Apply ROI analysis to marketing campaigns, equipment purchases, new hires, and other spending decisions
- Target 10–15% ROI as a general benchmark, adjusting for your industry, risk level, and time frame
- Combine ROI with other metrics like payback period and risk assessment, since ROI alone doesn't capture time factors or qualitative benefits
What is return on investment (ROI)?
Return on investment (ROI) is a financial metric that measures the profit or loss generated by an investment relative to its cost. Expressed as a percentage, ROI helps you evaluate whether your business spending is delivering worthwhile returns, as an ROI lower than the rate of return on low-risk investments like term deposits raises questions about the overall investment.
You can use ROI to evaluate common business decisions:
- Expansion: opening new locations or purchasing equipment
- Marketing: running advertising campaigns or promotions
- Operations: switching suppliers or upgrading systems
- Staffing: hiring new employees or investing in training
Understanding the difference between ROI and rate of return helps you choose the right metric.
ROI vs rate of return: ROI measures total profitability as a single percentage, regardless of how long the investment takes. Rate of return (ROR) factors in specific time periods, making it useful for comparing investments of different durations.
How to calculate ROI
The ROI formula calculates your return as a percentage:
(Net Profit ÷ Cost of Investment) × 100 = ROI%
To use this formula, you need three figures:
- Cost of investment: the total amount you spent upfront
- Total return: all income or value generated from the investment
- Net profit: your total return minus your cost of investment
A positive percentage means you made money. A negative percentage means you lost money.
ROI calculation examples
Here are two common examples of how you can use ROI in your business.
Scenario 1: A marketing campaign
A kombucha company spent $4,000 on a one-month advertising campaign. The campaign generated $6,500 in new sales.
- Calculate net profit
$6,500 (total return) − $4,000 (investment) = $2,500
- Apply the ROI formula
($2,500 ÷ $4,000) × 100 = 62.5%
What this means: The campaign returned 62.5% on the investment. For every dollar spent, the company earned $1.63 back (the original dollar plus 63 cents profit).
Scenario 2: New equipment
A construction business purchases a new excavator for $50,000. In the first year, the machine helps complete extra jobs that generate $70,000 in additional revenue.
- Calculate net profit
$70,000 (total return) − $50,000 (investment) = $20,000
- Apply the ROI formula
($20,000 ÷ $50,000) × 100 = 40%
What this means: The excavator delivered a 40% return in its first year. The business earned back the purchase cost plus an additional $20,000 in profit.
Once you understand how to calculate ROI, the next question is what number to aim for.
What is a good ROI?
A good ROI for small businesses is typically 10–15% or higher, though the right target depends on your specific situation.
What determines a good ROI:
- Risk level: higher-risk investments should deliver higher returns to justify the uncertainty
- Time frame: short-term investments often need higher ROI than long-term ones
- Industry norms: compare your results to similar businesses in your sector
- Strategic value: some investments accept lower ROI for long-term benefits like market positioning
An ROI above your target is strong. An ROI below it signals the investment may not be worth repeating.
Knowing what counts as a good ROI is helpful, but understanding why this metric matters can help you use it more effectively.
Why ROI matters for your small business
ROI matters because it turns guesswork into data-driven decisions. Instead of hoping an investment pays off, you can measure exactly how much profit it generates.
For small businesses, ROI helps you:
- Identify winners and losers: see which investments make money and which drain resources
- Compare options objectively: evaluate different opportunities using the same metric
- Justify spending: demonstrate returns to partners, investors, or yourself
- Plan ahead: forecast potential returns before committing funds
- Track performance: monitor whether marketing, equipment, or hiring decisions deliver expected results
While ROI is valuable, it's not a perfect measure.
What are the limitations of ROI?
ROI is a useful starting point, but it doesn't tell the whole story. Use it alongside other measures when making business decisions.
What ROI doesn't account for:
- Time factor: a 20% ROI over one year is far better than 20% over five years, but the formula treats them equally
- Hidden costs: depreciation, maintenance, and financing costs reduce true profitability but may not appear in basic ROI calculations
- Qualitative benefits:brand reputation, customer satisfaction, and employee morale improvements don't show up as numbers
- Risk levels: a high-risk investment and a safe one might show identical ROI, despite very different profiles
Pair ROI with metrics like payback period and risk assessment for a more complete picture.
Understanding ROI's strengths and limitations helps you apply it effectively.

FAQs on return on investment (ROI)
Here are answers to common questions about calculating and applying ROI in your business.
How long does it take to see a return on investment?
The timeline varies by investment type. Marketing campaigns may show returns within weeks, while equipment or training investments often take months or years to deliver positive ROI.
What if my ROI is negative?
A negative ROI means your investment cost more than it returned. This is common for small businesses. Analyse what went wrong: poor planning, external factors, or flawed assumptions. Use those insights to improve future decisions.
Can I calculate ROI for non-financial benefits?
ROI requires measurable financial figures, so benefits like brand reputation, employee morale, or customer satisfaction don't fit the standard formula directly. You can estimate their value by tracking related metrics, such as customer retention rates or employee turnover costs, then applying those figures to an ROI calculation.
What costs should I include when calculating ROI?
Include all costs directly tied to the investment: purchase price, installation, training, ongoing maintenance, and financing charges. Focus only on costs directly tied to the investment, setting aside sunk costs (money already spent) and unrelated business expenses that exist regardless of the investment.
