The ARR Trap: Grey-Zone Tactics SaaS Founders Use to Pump Their Numbers
Annual Recurring Revenue (ARR) has become the gold standard in the SaaS world. Investors use it to value companies, founders proudly cite it in pitch decks and on LinkedIn, and the media point to it as proof of growth. Yet ARR is not a standardized accounting figure — and that is precisely what makes it vulnerable to manipulation.
What ARR actually measures
Annual Recurring Revenue describes the annualized value of recurring income from subscription contracts. The calculation is straightforward: Monthly Recurring Revenue (MRR) multiplied by twelve. A customer paying 500 euros per month therefore generates 6,000 euros in ARR.
Unlike traditional revenue figures, however, ARR is not an accounting metric. Neither GAAP nor IFRS prescribe what counts as ARR. Every startup can apply its own definition, as long as it discloses that definition to investors. “ARR is an operational metric, not a financial accounting one,” says a Vienna-based venture capital partner who wishes to remain anonymous. “That makes it flexible. And that is exactly what makes it vulnerable.”
“The best companies communicate ARR with context,” says one founder who successfully sold his startup. “They explain what they include, what they don’t, and they deliver the supporting metrics alongside it.”
Three interests, one metric
The popularity of ARR can be explained by the overlap of different interests. For founders, the metric offers a forward-looking view: it shows what the company would theoretically earn if all current contracts ran for a full year. For young companies without profitable annual results, that is an important argument.
Investors, in turn, use ARR as a basis for comparison. SaaS companies are typically valued as a multiple of their ARR. Industry data points to multiples between 5x and 20x, depending on growth rate, market, and profitability. A company with 5 million euros in ARR and a 10x multiple arrives at a valuation of 50 million euros on paper.
For the public, finally, ARR suggests stability: recurring revenue sounds more reliable than one-off sales.
Where the metric has its grey zones
Because ARR is not standardized, room for interpretation arises. Industry insiders identify several recurring practices that companies use to make the number look better.
One common method is to report one-time income such as setup fees, onboarding costs, or implementation services as part of ARR. An initial setup worth 10,000 euros is declared as an “annual license” and thus flows into recurring revenue — even though it occurs only once.
Contract terms can also be used to steer the figure. When startups offer discounts for converting short trial contracts into annual contracts, the entire annual value is immediately counted as ARR, even if the customer could theoretically cancel after a short time.
A third grey zone involves cancellations. Not every company adjusts ARR immediately after a cancellation. Some wait until the formal end of the contract, which can take weeks or months. During that period, the customer continues to be reflected in the metric.
Then there is the question of gross versus net ARR. Upsells to existing customers (expansion revenue) are booked as new ARR, without offsetting cancellations (churn). The more meaningful Net Revenue Retention (NRR) often remains in the background. Finally, there are timing strategies around quarterly closings: contracts that only begin in the following year are sometimes booked as ARR in the current quarter — a practice particularly widespread in the fourth quarter.
ARR is a projection, not a result
The key difference compared with traditional revenue metrics such as Trailing Twelve Months (TTM) lies in the character of the figure. While TTM reflects the income actually earned over the past twelve months, ARR is a snapshot with a projective character. It shows what could be earned under status-quo conditions over the next twelve months — not what has already been booked.
For investors, that means ARR should never be viewed in isolation. The number becomes more meaningful only in the context of Net Revenue Retention, churn rate, customer acquisition cost, and gross margin. Without these supporting metrics, ARR remains what its critics accuse it of being: a hopeful calculation with a polished surface.
