If one value is uncertain, try a low and high version. That gives you a better feel for how sensitive the gmroi calculator — gross margin return on investment result is.
Step-by-step
- Enter Average inventory cost using the unit shown on the form.
- Add Starting inventory cost with the same time period, unit system, or scenario in mind.
- Look at End Inv, Beg Inv, Avg Inv before making a decision.
- Adjust one value at a time if you want to compare different gmroi calculator — gross margin return on investment cases.
Input guide
- Currency lets you choose the scenario that matches your case, such as USD, PKR, EUR, GBP.
- Average inventory cost is the number you enter for the calculation, shown in USD.
- Starting inventory cost is the number you enter for the calculation, shown in USD.
- Final inventory cost is the number you enter for the calculation, shown in USD.
- Gross profit is the number you enter for the calculation, shown in USD.
Example Calculation
For example, enter Average inventory cost = 10 USD, Starting inventory cost = 1 USD, Final inventory cost = 1 USD, Gross profit = 1 USD. The result is end inv of Calculated. Replace the example numbers with your own values when you are ready to check your case.

- Choose usd in Currency when it best matches your situation.
- For Average inventory cost, a practical example would be 10 USD, as long as that reflects your real scenario.
- For Starting inventory cost, a practical example would be 1 USD, as long as that reflects your real scenario.
- For Final inventory cost, a practical example would be 1 USD, as long as that reflects your real scenario.
- For Gross profit, a practical example would be 1 USD, as long as that reflects your real scenario.
Understanding Your Results

Useful result lines include End Inv, Beg Inv, Avg Inv, Gmroi, Gmroi2. Read them together instead of relying only on the first number.
If the answer is much higher or lower than expected, check the basics first: units, decimal places, percentages, date ranges, and whether each input belongs to the same case.
