How to use the arr growth calculator
Prepare the values for this calculation
Calculate annual recurring revenue growth from starting and ending ARR. Use the formula below to check that it answers your question. Read the input units before transferring figures from a statement, measurement or dataset.
Enter and check each input
- Starting ARR: enter a value at least 1e-06. Use the unit named in the label or selected above. Do not leave this required field blank.
- Ending ARR: enter a value at least 0. Use the unit named in the label or selected above. Do not leave this required field blank.
The input table gives a complete example. Keep units and time periods consistent across related fields.
Calculate and resolve any input error
Choose Calculate after entering the values. Changes also update the answer after a short pause. If an error appears, follow its message, correct the field and calculate again. Reset restores the example values.
Interpret the answer
Check ARR growth first. With the unchanged example inputs, it is 30%. Compare the additional metrics with the primary result; each has its own label and unit.
Compare and keep a useful result
For a controlled comparison, keep every other example input unchanged and change Starting ARR from 500000 to 550000. The resulting ARR growth is 18.1818181818%. This illustrates the equation’s response to that input, rather than a forecast of real events.

ARR Growth Calculator formula
ARR growth = (ending ARR−starting ARR)/starting ARR × 100%.
Inputs and units
| Input | Format / range | Example |
|---|---|---|
| Starting ARR | minimum 1e-06 | 500000 |
| Ending ARR | minimum 0 | 650000 |
Worked example
Using the example inputs above, the arr growth is 30%.
- ARR growth
- 30%
- Absolute change
- 150,000
Results and assumptions
The output uses the arr growth convention and formula shown above. Match the entered units and source assumptions when comparing results.
Rates, fees and tax assumptions are entered values. This calculation does not quote a lender, determine a tax liability or guarantee an investment return.
Fix an input or unexpected result
Starting ARR is required. Enter starting arr using the format and bounds in the input table. Zero and an empty field are different: use zero only if it is allowed and represents your data.
If your answer differs from the example, choose Reset and compare every field, including selected units and options. Check percentage versus decimal entry and whether values describe the same period. Round only the final displayed answer when reproducing the formula.
If a discrepancy remains, report the calculator issue with the page address, non-sensitive example inputs, actual result, expected result and a reference for your calculation.
