ARPA Calculator 2026 Average Revenue Per Account

Total recurring revenue divided by total accounts. The single input most predictive of how your SaaS economics work: high ARPA tolerates long sales cycles and high CAC; low ARPA demands fast, cheap acquisition. Trend matters more than the absolute number.

Inputs

ARPA (per Account)
$500/mo
Annualised: $6,000/yr
ARPU (per User)
$55.56/mo
9.0 users per account
Segment fit: Mid-market B2B

ARPA of $500/month is typical for this segment. Benchmark your CAC, sales cycle, and gross margin against comparable peers, not against generic SaaS averages.

ARPA vs ARPU

ARPA (per Account)

Total MRR / Total Accounts

Revenue per customer relationship. Tracks the value of the full account. Use for ARR-band segmentation and LTV input.

ARPU (per User)

Total MRR / Total Users (Seats)

Revenue per seat. Useful for seat-based pricing models. Lower than ARPA when accounts have multiple users.

ARPA ranges by segment

Frequently Asked Questions

What is ARPA?
ARPA (Average Revenue Per Account) is total recurring revenue divided by the total number of accounts. Formula: ARPA = Total MRR / Total Accounts (monthly basis), or ARR / Accounts for annual. It captures the typical revenue per customer at a point in time. Tracking ARPA over time reveals whether your account-level revenue is growing (through upsell, expansion, mix shift to higher tiers) or shrinking (through downgrades, mix shift to SMB).
What is the difference between ARPA and ARPU?
ARPA is per account (per customer organisation). ARPU is per user (per seat). In B2B SaaS with seat-based pricing, ARPU is typically much lower than ARPA because one account can have many users. A company with $1,200 ARPA across 100-seat accounts has $12 ARPU. Use ARPA for revenue per customer relationship; use ARPU for unit economics on per-user contribution.
Why does ARPA matter for SaaS valuation?
ARPA correlates with go-to-market efficiency. High ARPA businesses (enterprise SaaS, $25K+ ARPA) can tolerate longer sales cycles and higher CAC because each customer generates more revenue. Low ARPA businesses (SMB SaaS, sub-$2K ARPA) need fast acquisition and low CAC because each customer cannot bear high acquisition cost. Investors model valuation differently for high-ARPA vs low-ARPA businesses; conflating the two leads to bad benchmark comparisons.
How does ARPA relate to LTV?
ARPA is the revenue input to LTV. Simple LTV formula: LTV = ARPA x Gross Margin / Churn Rate. Improving ARPA (by raising prices, adding seats, moving customers to higher tiers) directly improves LTV without any change to churn or margin. This is why pricing increases and tier upgrades are the highest-leverage moves in LTV improvement; they compound through the entire customer base immediately.
What is a good ARPA benchmark?
ARPA varies massively by segment. B2C SaaS: $5-30/month. SMB B2B: $50-500/month. Mid-market B2B: $500-4,000/month. Enterprise B2B: $4,000-40,000+/month. There is no universal ARPA benchmark. The useful metric is ARPA trend over time within your business; flat or growing ARPA signals pricing and expansion working; declining ARPA signals mix shift down market or pricing pressure.
