Annual Recurring Revenue (ARR)
ARR is the annualized value of your recurring subscription revenue. It normalizes your monthly recurring revenue (MRR) into an annual sum (MRR × 12). For enterprise SaaS companies with multi-year contracts, ARR is the standard metric. If a customer signs a 3-year, $150,000 contract, that is $50,000 in ARR. Investors value SaaS companies based on ARR multiples (e.g., 10x ARR) because it represents highly predictable, compounding future revenue.
The Trap
The most common trap is including non-recurring revenue like one-time implementation fees or professional services in the ARR calculation. If you charge $20,000 for software (recurring) and $10,000 for setup (one-time), your ARR from that customer is only $20,000. Inflating ARR with one-time fees destroys the predictability that makes ARR valuable in the first place.
What to Do
Calculate your true ARR strictly from recurring subscriptions: Current MRR × 12. Alternatively, sum the total annual value of all active contracts. Track your ARR Growth Rate year-over-year. To reach a $100M valuation at a conservative 10x multiple, you need to build an engine that consistently generates $10M in true ARR.
Formula
In Practice
When Zoom went public, their ARR growth was legendary. In their IPO prospectus, they didn't just show total revenue; they highlighted that their ARR from customers contributing >$100,000 grew 118% year-over-year. This proved they weren't just adding small accounts, but aggressively expanding enterprise contracts, leading to their massive initial public valuation.
Pro Tips
- 01
Use 'Committed ARR' (CARR) to include signed contracts that haven't launched yet, minus known upcoming churn. This gives the most accurate forward-looking picture.
- 02
ARR implies a subscription that lasts at least a year. If your average customer churns in 4 months, you shouldn't be using ARR as your primary metric—use MRR instead.
Myth vs Reality
Myth
“ARR is just Total Annual Revenue”
Reality
Total Revenue includes EVERYTHING (services, one-off hardware, one-time fees). ARR only includes the predictable, subscription-based revenue.
Myth
“You calculate ARR by looking at the last 12 months”
Reality
ARR is a forward-looking run rate. It's MRR × 12 based on THIS month's active subscriptions, not a historical sum of the past year.

Snowflake
2019-2020
Snowflake went public with a consumption-based pricing model, but translated their usage into 'Product Revenue' run rates that functioned like ARR. By their IPO, they had 56 customers contributing >$1M in trailing 12-month revenue. Their incredibly high Net Revenue Retention (158%) meant their ARR base compounded automatically, leading to the largest software IPO in history at the time.

Fast
2021-2022
One-click checkout startup Fast raised $102M in Series B funding at a $580M valuation. Despite the massive valuation, leaked reports showed their actual revenue in 2021 was roughly $600,000 total. The company had almost no true predictable ARR, burning $10M a month to acquire users with tiny transaction volumes.

Decision scenario
The Contract Structure
You are closing your first $200K enterprise customer. They want to pay the $200K over 2 years, but they need massive custom development (worth $80K) done in the first month.
