SaaS SLA Credit Liability Calculator

Estimate service credits owed when uptime drifts below your SLA. Provide covered MRR, the uptime guarantee, and observed uptime to surface the shortfall, equivalent downtime minutes, credit percentage after multipliers, and the cash liability hitting invoices.

Total MRR tied to the uptime guarantee for the billing cycle under review.
Availability percentage promised in your SLA terms.
Observed uptime for the same billing window, including incident downtime.
Optional. Defaults to 1×. Some contracts credit two or more times the pro-rated downtime.
Optional. Defaults to 100%. Adjust if only a slice of MRR is eligible for credits.

This tool assumes credits are calculated as a simple percentage of affected MRR. Confirm the exact credit schedule, exclusions, and claim windows in your SLA before issuing adjustments.

FAQ

How do staged credit tiers map here?

Enter the multiplier that matches the tier triggered by your downtime. For example, a 50% credit tier can be modelled with a multiplier that produces the same percentage shown in the contract.

Can I include penalty interest?

Add penalty interest or legal fees to the MRR input before running the calculation so the credit liability reflects the extra reimbursement you owe.

What if the outage only hit one region?

Reduce the impacted revenue percentage to the share of MRR located in the affected region so the liability aligns with contractual scope.

Additional Information

  • Downtime minutes assume an average calendar month (30.44 days) for quick stakeholder reporting.
  • Credit percentage scales the SLA shortfall by any multiplier promised in the contract, then caps at 100% of eligible revenue.
  • Impacted revenue lets you carve out customers excluded from SLA remedies or on usage-only billing plans.
