How to use this calculator

Enter the investment amount, revenue generated, total costs, and investment period in months. The calculator estimates profit, ROI, payback period, and annualized ROI.

What the result means

ROI shows how much return an investment generates compared with the amount invested. Positive ROI is good, but payback speed and risk also matter.

Profit = Revenue - Total Costs. ROI = Profit / Investment x 100. Payback Period = Investment / Monthly Profit.

ROI should be compared with risk, time, cash flow, and alternative uses of capital.

Example calculation

If investment is $20,000, revenue is $50,000, and costs are $30,000, profit is $20,000 and ROI is 100%.

Tips for better results

  • Include hidden costs such as labor, maintenance, fees, and taxes.
  • Compare ROI with payback period, not ROI alone.
  • Run best-case and worst-case assumptions before investing.

FAQ

What is a good ROI for a small business investment?

A good ROI depends on risk and time period, but many small business owners look for returns above 20% when capital, labor, and risk are involved.

How long should it take to recover a business investment?

Many owners prefer a payback period under 12 to 24 months, but large equipment, property, and long-term growth investments may take longer.

Is 20 percent ROI considered good?

A 20% ROI can be good if the risk is moderate and the return period is reasonable. For high-risk investments, owners may require a higher ROI.

How do I calculate ROI on new equipment purchases?

Subtract total equipment-related costs from additional revenue or savings, then divide the profit by the equipment investment amount.

Which small business investments generate the highest ROI?

High-ROI investments often include pricing improvements, conversion optimization, customer retention, automation, staff training, and high-performing marketing channels.
