ROI Calculator
Calculate return on investment - simple ROI, annualized ROI, and compare multiple investments side by side.
Total value received (not just profit)
Understanding ROI
- Simple ROI = (Net Profit / Cost of Investment) x 100. Quick but ignores the time dimension.
- Annualized ROI = ((Final Value / Cost) ^ (1/Years) - 1) x 100. Lets you compare investments of different durations on an equal footing.
- Payback period tells you how long until you recover your initial investment, assuming returns arrive linearly.
- Limitations: ROI does not account for risk, cash flow timing, or opportunity cost. A 50% ROI over 10 years is very different from 50% ROI over 1 year.
- Always consider annualized ROI when comparing investments with different timeframes.

Understanding return on investment for business decisions
Return on investment (ROI) is the most widely used metric for evaluating business expenditures, capital investments, and project proposals. At its simplest, ROI measures how much profit or loss an investment generates relative to its cost, expressed as a percentage. A positive ROI means the investment returned more than it cost; a negative ROI means it lost money.
The limitation of simple ROI is that it ignores time. A 50% return over one year is very different from a 50% return over ten years. Annualized ROI solves this by expressing the return as a compound annual growth rate (CAGR), making it possible to compare investments with different timeframes on an equal basis.
How to use this ROI calculator
- Enter the initial investment amount (the total cost outlay at the start).
- Enter the final value or total return received from the investment.
- Specify the investment period in years to calculate annualized ROI.
- To compare investments, add up to three options side by side and review the annualized ROI and payback period for each.
ROI benchmarks for Australian businesses
When comparing multiple investment options - whether that is new equipment, software, marketing campaigns, or hiring decisions - annualized ROI provides the fairest comparison. Australian businesses typically target different ROI thresholds depending on the investment type: capital equipment in mining and construction often requires 20-30% annualized ROI to justify the risk, software and SaaS investments are expected to pay back within 12-18 months, and marketing spend is benchmarked against a 5:1 return ratio. However, ROI alone should not drive the decision. Consider cash flow timing, risk, strategic value, and opportunity cost alongside the numbers.
What is the ROI of automating accounts payable?
Most businesses that automate AP see ROI within 3-6 months through reduced processing time, eliminated data entry errors, captured early payment discounts, and freed-up finance staff time. The typical cost to process an invoice manually in Australia is $15-$30; automation brings that below $5. For an industrial business processing 500 invoices per month, that is a saving of $5,000-$12,500 monthly - delivering a clear, measurable return that compounds as invoice volumes grow.
