How to use

Enter the values used by arr

Calculate annual recurring revenue from monthly recurring revenue. Enter the assumptions for the same time period and currency, and check any minimum or maximum values displayed next to the input fields.

01
Record your inputs

Monthly recurring revenue.

02
Compare a second case

Change one variable so you can see the effect without mixing several assumptions.

03
Check the calculation

The worked example below shows the formula and the independently rendered default-input results.

Complete worked example

Calculate arr from sample inputs

These are the same starting values loaded into the interactive calculator above. The displayed results below come from the same calculation engine as the live tool.

Step 1 — Record the inputs

Monthly recurring revenue$15,000

Step 2 — Identify the formula

FORMULAARR = MRR × 12

Step 3 — Substitute the values

For this exact worked case, use Monthly recurring revenue = $15,000. Replace named formula variables with their input values as shown below. Keep the units consistent; a percent is divided by 100 wherever the model requires a decimal rate.

NUMERIC SUBSTITUTIONARR = $15,000 × 12

Step 4 — Read the calculated answer

Annual recurring revenue$180,000.00
Monthly recurring revenue$15,000.00

Rounding follows the calculator display: whole units may be rounded up when an indivisible unit is required, while other values typically show up to two decimal places. The result is conditional on the entered assumptions, not a market quotation.

Decision interpretation

How to interpret this arr result

ARR annualizes current recurring revenue. It is not a cash forecast and does not include one-time revenue.

Apply the arr result to a decision using the same scope, time period and units as your recorded inputs.

Scenario comparison

Change one relevant assumption at a time and record which scenario changes the arr outcome materially.

Assumptions and limitations

The arr calculation covers the listed variables only. Confirm any omitted costs, eligibility rules and definitions before acting.

  • Monthly recurring revenue: Enter a finite monetary value of at least 0. Use a consistent definition across comparison cases.

Frequently asked questions

What does this calculator include?

It uses the named inputs above and the formula shown in the worked example. No other fees, revenue streams, or external data are automatically included.

Why could my real result be different?

The arr calculation covers the listed variables only. Confirm any omitted costs, eligibility rules and definitions before acting.

How should I compare two results?

Change one relevant assumption at a time and record which scenario changes the arr outcome materially. Record the assumption that changed so a higher or lower answer is interpretable.

Use with care

What this estimate does—and does not—include

This tool is designed for quick planning and comparison. For tax, accounting, legal, investment, lending, or other regulated decisions, verify the result against the rules and assumptions that apply to your situation.

CalcScoutHQ shows the calculation logic so you can check assumptions, understand the result, and reproduce the math independently when needed.
