ARR (Annual Recurring Revenue) and MRR (Monthly Recurring Revenue) represent the same
underlying metric at different time scales. The relationship is simple:
ARR = MRR × 12MRR = ARR ÷ 12
But founders mix up these numbers constantly — especially when dealing with annual-plan
customers, investor conversations, or financial models that use both figures.
When to use ARR vs MRR
Use MRR when:
- Tracking month-to-month growth velocity
- Computing churn impact (churn is a monthly rate)
- Calculating burn rate vs revenue
- Running short-term models (< 1 year)
Use ARR when:
- Talking to investors (most SaaS valuations use ARR multiples)
- Comparing to industry benchmarks ($1M ARR, $10M ARR milestones)
- Reporting to your board
- Calculating revenue multiples (ARR / ARR multiple = company value)
Annual plan revenue recognition
A customer who pays $1,200 upfront for a year contributes $100/month to MRR and
$1,200 to ARR — but the cash arrives all at once. This distinction matters for
runway calculations: ARR and cash flow are not the same thing.
Frequently asked questions
Is ARR the same as annual revenue?
No. ARR includes only recurring subscription revenue. One-time setup fees, professional
services, and non-recurring revenue are excluded from ARR. This is what makes ARR a
useful measure of predictable, recurring business health.
What ARR multiple should I use for valuation?
SaaS valuations typically range from 5–15× ARR depending on growth rate, net retention,
and market conditions. At $1M ARR growing 100%+ YoY, 10–15× is common. At $5M ARR
growing 50% YoY, expect 6–10×.
When to use ARR vs MRR in investor updates, board decks, and internal reporting — and how to calculate each correctly from your subscription data.
ARR and MRR measure the same thing — recurring revenue — at different time horizons.
Choosing which to report depends on your business model and audience.
When to use MRR
Use MRR when:
- Your billing cycle is monthly
- You are tracking short-term growth momentum
- You want to see the impact of churn or expansion within 30 days
- You are in early stage (MRR < $100k) where monthly changes are meaningful
When to use ARR
Use ARR when:
- You have annual contracts or significant mix of annual billing
- Reporting to investors (VCs and PE firms use ARR as the standard)
- You are above $1M MRR (ARR communication is cleaner: "$12M ARR")
- You want to compare to public SaaS benchmarks (all use ARR)
The conversion
ARR = MRR × 12. Simple — but only valid if your subscription base is stable.
If you have high monthly churn, ARR is a misleading forward projection.
What to include in ARR/MRR
Include: recurring subscription revenue (monthly and annual)
Exclude: one-time setup fees, professional services, variable usage above a
committed floor, discounts applied at the invoice level
ARR vs MRR: Which Should Your SaaS Report to Investors?
When to report ARR vs MRR to investors and board members — with guidance on which metric is appropriate at each stage and how to avoid common misreporting.
Both ARR and MRR measure subscription revenue, but they're used in different
contexts. Here is the convention that most investors and board members expect.
ARR vs. MRR: the rule of thumb
Use ARR for: investor updates, term sheet negotiations, valuations,
public comparisons, and anything with an annual time horizon.
Use MRR for: monthly operational reviews, churn analysis, growth rate
tracking, sales team quotas, and finance budgeting.
When does ARR = MRR × 12?
Always — ARR is simply MRR × 12. The question is which frame of reference you
use. Reporting "$100k ARR" and "$8,333 MRR" conveys the same underlying revenue.
Common misreporting mistakes
Mixing one-time and recurring revenue: ARR/MRR should only include
contractually recurring revenue. One-time setup fees, professional services,
and hardware are excluded.
Inflating with full-contract value: a 3-year contract for $120k paid upfront
is $40k ARR (the annual portion), not $120k ARR.
Counting trials or freemium users: ARR/MRR is for paying customers only.
Not netting downgrades and churn: net ARR = new ARR + expansion − churn −
contraction. Gross ARR only counts new bookings.
ARR milestones investors care about
$1M ARR: the first significant proof-of-concept
$3M ARR: transition from founder-led sales to first AEs
$10M ARR: Series B territory, repeatable sales motion
$30M+ ARR: growth equity / late stage

the two metrics instantly.
ARR to MRR: How Annual Plan Customers Should Be Counted
How to correctly convert an annual-plan customer's payment into MRR, why the cash you receive and the MRR you report are different numbers, and common reporting mistakes.
Annual-plan customers are where MRR and ARR reporting most commonly goes wrong, because
the cash arrives all at once but the revenue recognition — and the MRR figure — should
be spread across the year.
The correct conversion
MRR contribution = Annual contract value / 12
A customer who pays $2,400 upfront for an annual plan contributes $200/month to MRR
— not $2,400 in the month they paid, and not $0 until renewal.
The mistake to avoid
Some teams book the full $2,400 as MRR in the month of payment, which spikes that
month's MRR and understates every other month — making growth trends impossible to read.
Others wait and add nothing until the next annual payment, which understates MRR all year
and misses the recurring nature of the revenue entirely. Both distort the metric MRR
exists to provide: a smooth, comparable, month-to-month view of recurring revenue.
Cash flow and MRR are not the same thing
This is the single most important distinction for annual-plan businesses. Cash flow
shows $2,400 landing in one month. MRR shows $200/month recognized evenly. Your runway
model should use cash flow; your growth-rate and investor reporting should use MRR. Mixing
the two — for example, using annual cash spikes to claim high "MRR growth" — misrepresents
the business.
ARR for a mixed monthly/annual customer base
ARR = MRR × 12
still holds once MRR is calculated correctly per the rule above — you don't need a
separate ARR formula for annual-plan customers, you just need MRR itself to be computed
correctly first.
Frequently asked questions
What happens to MRR when an annual customer churns mid-contract?
Most SaaS companies remove the customer's MRR contribution from that point forward, even
though they may have already collected the full annual payment — MRR reflects ongoing
recurring revenue, not cash already banked.
Should upfront annual discounts change the MRR calculation?
No — MRR should reflect the actual contract value the customer is paying, discount
already applied, divided by 12. The discount affects the dollar amount, not the method.

value into its correct monthly MRR contribution.
