Renewal Revenue Calculator

Calculate your annual contract renewal rate and the ARR at risk when contracts come up for renewal.

Renewal revenue is the ARR recovered when customers on annual contracts renew for another year. Renewal rate = ARR renewed ÷ ARR up for renewal × 100. A 90% renewal rate on $1M of ARR up for renewal means $900K retained and $100K lost. Tracking renewal rate separately from monthly churn is essential for annual-contract SaaS businesses.

ARR Up for Renewal

Total ARR from contracts expiring this period

ARR Successfully Renewed

ARR that actually renewed (at same or higher value)

Expansion at RenewalOptional — shows net renewal rate

Additional ARR added at renewal time (upsells closed during renewal)

The Formula

Renewal Rate = ARR Renewed ÷ ARR Up for Renewal × 100

In plain English

Divide the ARR that was successfully renewed by the total ARR that was up for renewal in the period. Multiply by 100.

Worked Example

ARR up for renewal: $500,000. ARR renewed: $450,000. Rate = $450K ÷ $500K × 100 = 90%. ARR lost: $50,000.

Renewal Rate vs Monthly Churn Rate

Monthly churn rate measures the percentage of all customers who cancel each month. Renewal rate specifically measures contract renewal success when an annual subscription expires — it's the most important retention moment for annual-contract SaaS businesses.

A company with a 90% annual renewal rate has a roughly 0.9% monthly churn equivalent — but renewal conversations happen once a year, not monthly. Building a 90-day renewal playbook (identifying at-risk accounts, QBR scheduling, commercial discussions) is different from day-to-day churn management.

Common Mistakes

⚠️

Starting renewal conversations too late

The worst time to discuss renewal is 2 weeks before expiry — by then, the customer has already decided. Best practice: start the renewal process 90 days before contract expiry for mid-market accounts, 120 days for enterprise.

⚠️

Not separating logo renewal rate from ARR renewal rate

A 90% logo renewal rate (90% of accounts renew) looks different if the 10% who don't renew are your largest accounts. Always track both logo renewal rate and ARR renewal rate to understand the revenue impact.

⚠️

Ignoring at-risk accounts until renewal time

Accounts that churn at renewal usually show warning signs 3–6 months earlier: declining usage, support tickets, champion job changes. A customer health score system identifies at-risk accounts early enough to intervene.
