ARR answers one question: if nothing changed today, how much revenue would our existing subscription book generate over the next twelve months? Everything else about SaaS reporting is a derivative of that number.
ARR, or annual recurring revenue, is the normalized annual value of a company's recurring subscription contracts. It counts the subscription portion of signed, active agreements, excluding one-time services and most usage overages. ARR is calculated by annualizing every active subscription and summing the result. It is the primary metric subscription businesses use for forecasting, valuation, and investor conversations because it isolates predictable, repeating revenue from everything else on the invoice.
The six things to get right about ARR before it ends up in a board deck or a term sheet. Each one is a place real companies lose credibility by reporting the wrong number.
ARR is the subscription portion of your active contracts, annualized. A monthly plan is multiplied by twelve. A multi-year contract is divided by its term to get the annual value. The point is to express every recurring agreement in the same, comparable, twelve-month unit so the whole book can be summed into one number.
ARR includes committed subscription fees under an active contract. It excludes one-time setup fees, professional services, implementation, training, hardware, and in most reporting conventions, usage overages. If the revenue would not reliably repeat next year under the same contract, it does not belong in ARR.
ARR equals the sum, across every active subscription, of its annualized recurring price. For a monthly plan, multiply the monthly fee by twelve. For a quarterly plan, multiply by four. For a two-year prepaid deal, divide the total by two. Then add every subscription together. That is the number.
ARR moves in four directions. New ARR comes from net new logos. Expansion ARR comes from existing customers buying more seats or upgrading tiers. Contraction ARR is downgrades. Churned ARR is cancellations. Net new ARR is the sum of all four: new plus expansion minus contraction minus churn. That is the growth signal.
Public and private subscription businesses are routinely valued as a multiple of ARR because it isolates predictable revenue. Boards forecast off ARR. Investors underwrite off ARR. Compensation plans are tied to ARR. The number earns outsized attention because it approximates the recurring economic engine of the business more honestly than top-line revenue.
The most common ARR mistake is accidentally including one-time revenue, counting bookings instead of active contracts, mixing a quarter of billings with a year of ARR, or forgetting to subtract applied discounts. Each error inflates the number in a way that looks fine on a slide and falls apart in diligence. Clean definitions prevent the embarrassment.
The ARR definition is short. The way ARR actually moves across a quarter is where most of the complexity hides. The six cards below are the mechanics every operator, founder, and finance lead should be able to explain in their sleep, because they come up on every board call and in every due-diligence conversation.
For every active subscription, take the recurring price and extend it to a twelve-month equivalent. A monthly subscription times twelve. A quarterly subscription times four. A two-year contract divided by two. Then sum every subscription in the book. That total is ARR as of the point in time you ran the calculation.
New ARR is the annualized subscription value of brand new customer contracts signed in the period. The deal must be signed and the subscription must be active in the measurement window. Pilots, free trials, and letters of intent are not new ARR. A signed order form with a start date is.
Expansion ARR is the annualized increase from upsells and cross-sells inside the existing customer base. More seats, higher tier, added modules, price step-ups at renewal. If the customer was already in the ARR book and is now contributing more, the delta is expansion. Expansion is the quietest growth lever and often the most profitable.
Contraction ARR is the annualized decrease from downgrades, seat reductions, or negotiated discounts on existing accounts. The customer stayed, but the contract shrank. Contraction is subtracted when calculating net new ARR and watched closely because it is often a leading indicator of a churn risk that has not yet decided to leave.
Churned ARR is the annualized value of the subscriptions that cancelled or did not renew in the period. It is the single hardest line in the ARR movement because it directly offsets new ARR and compounds against future growth. Separating voluntary churn (the customer chose to leave) from involuntary churn (failed payment) matters for the fix.
Net new ARR equals new plus expansion minus contraction minus churn. It is the honest growth rate of the subscription book. A company can post a large new ARR number while net new ARR is flat because churn and contraction erased the growth. Reporting both numbers side by side is the standard the mature boards expect.
The scariest mistake in ARR is not the math. It is categorizing non-recurring revenue as recurring. The cleanest teams write down an ARR policy, publish it internally, and apply it the same way every month. The six items below are the standard inclusions and exclusions that hold up under auditor and investor scrutiny.
The recurring fee under an active, signed contract. A monthly, quarterly, or annual subscription with a defined price and term. If the customer has agreed to pay a repeating amount for access to the product, that amount belongs in ARR, annualized to twelve months regardless of billing cadence.
If a usage-based plan has a committed floor the customer pays regardless of consumption, the floor is treated as recurring and included in ARR. The variable consumption on top of the floor is typically excluded from ARR and reported separately as usage revenue, because next period's usage is not contractually guaranteed.
Implementation, onboarding, training, custom development, migration projects. These are real revenue, but they do not repeat next year under the same contract. They belong in a services or professional-services line, not in ARR. Including them makes the subscription business look larger than it is.
In most reporting conventions, usage above a plan floor is excluded from ARR because it is not committed. Some companies annualize a trailing average of overages into a separate "run-rate" number, but that number is not ARR and should not be labelled as such. Keep the two cleanly separate.
If the business resells hardware, phone numbers, SMS traffic, or any third-party cost, the resold revenue is typically excluded from ARR because it is not the product's recurring software value. Report it as resale or pass-through revenue, often net of the carrier or vendor cost, outside the ARR line.
ARR is the net price the customer actually pays after discounts. A twelve-month promo at half price is annualized at the discounted rate for the duration of the discount, not the list rate. When the promo ends, the ARR step-up is treated as expansion ARR, assuming the customer continues on the new price.
A finance team can build an ARR report in a spreadsheet, and many still do. The problem is reconciling the spreadsheet to the actual customer book every month. A CRM shortens the loop by holding the three data sources ARR movements come from: closed-won deals, renewals, and expansion activity on the same accounts the sales team is already working. The six cards below are the pattern Strkr customers use.
Every new logo deal that closes carries the annualized subscription value as a field on the opportunity. When the stage flips to closed-won, that value is new ARR for the period. The CRM is the system of record for the deal, so the ARR total ties directly to the sales activity leadership already reviews weekly.
A renewal pipeline shows every subscription expiring in the next ninety days with the owning customer success manager, the renewal amount, and the risk level. The CRM lets the team work the renewal like any other deal, which turns churn from a surprise in the finance report into a managed workflow in the sales motion.
Expansion ARR is tracked as its own deal type on the existing account, with its own pipeline stage. When a customer adds seats or upgrades a tier, the deal records the increase and the stage advances to closed-won. The expansion number in the ARR report is the sum of those closed-won expansion deals in the period.
Because every subscription record is tied to an account, the CRM rolls ARR up by segment, industry, geography, product, cohort, and rep. The weekly revenue meeting can slice the number by any dimension the business cares about, without exporting data to a spreadsheet and losing a day in reconciliation.
When ARR goes up or down, the CRM records the deal, the user, the date, and the field change behind the movement. That audit trail is what makes an ARR report defensible in a board meeting or an investor diligence. "Where did that number come from?" has a one-click answer instead of a spreadsheet forensic exercise.
The CRM takes the open pipeline, applies stage-based probability, and projects the ARR adds for the quarter. The projected number sits next to the committed ARR from already-closed deals, so leadership sees both the floor (what has already landed) and the realistic add (what the open book will likely deliver) in one view.
Strkr is a CRM that captures new ARR from closed-won deals, expansion ARR from upsell pipelines, and churned ARR from the renewal workflow, all against the same account record. No spreadsheet reconciliation at month end. The ARR report ties to the system the sales team is already using.
Revenue, as reported on an income statement, is all money earned in a period under accounting rules. ARR is a subset: only the recurring subscription portion of active contracts, annualized. Services, one-time fees, hardware resale, and in most conventions usage overages are in revenue but not in ARR. ARR is a management metric that approximates the recurring engine of the business, while revenue is the full accounting number.
For every active subscription, annualize the recurring price (monthly fee times twelve, quarterly fee times four, multi-year total divided by the number of years), then sum across all active subscriptions. The resulting total is ARR at that point in time. Movement across a period equals new ARR plus expansion ARR minus contraction ARR minus churned ARR, which gives you net new ARR for the period.
MRR is monthly recurring revenue. ARR is annual recurring revenue. They measure the same thing on different cadences. For a book made up only of monthly subscriptions, ARR equals MRR times twelve. In practice, most subscription businesses have a mix of monthly, annual, and multi-year contracts, so operators track both and reconcile them to the same contract list.
The committed floor on a usage-based plan is usually included in ARR because it is contractually recurring. Variable usage above the floor is usually excluded, because next period's consumption is not guaranteed. Some teams report a separate "run-rate" number that annualizes a trailing average of usage, but that number is not ARR and should not be labelled as such.
Net new ARR is the honest growth number of the subscription book. It equals new ARR plus expansion ARR minus contraction ARR minus churned ARR. A business can post a strong new ARR quarter while net new ARR is flat because churn and contraction erased the growth. Reporting both numbers side by side is the standard mature boards expect.
Including non-recurring revenue like implementation fees or hardware, counting bookings instead of active contracts, mixing quarterly billings with annual ARR, forgetting to apply discounts to the annualized value, double-counting a renewal as both a renewal and a new deal, and not separating variable usage from the committed subscription floor. Each inflates the number in a way that looks fine on a slide and falls apart in diligence.
Subscription businesses are routinely valued as a multiple of ARR because it isolates predictable, repeating revenue. A business with high ARR, high retention, and healthy net new ARR growth has a far more valuable recurring engine than a business with the same top-line revenue made up of one-time services. ARR is the metric that captures that quality distinction, which is why it sits at the top of almost every SaaS term sheet and board deck.
Monthly for internal operating cadence, quarterly for board reporting, and at a point-in-time snapshot for any investor conversation. The point-in-time ARR number should always be labelled with the date it was taken, because the book moves every day. Many teams also publish a trailing twelve-month view of net new ARR so the growth trajectory is visible, not just the ending balance.
