SLA credits

Missing SLA has a contract price.

SLA credits are usually the cheap part of an outage — but they are the part that is contractually guaranteed. Enter your SLA target, actual uptime achieved, and monthly fee to estimate the credit owed under a typical tiered schedule.

Tier schedule

An illustrative, common tier structure.

Real SLA credit schedules vary by contract. This calculator uses a common three-tier structure as a starting point — replace it with your actual contract terms before using a figure externally.

Uptime achieved Tier Credit
At or above SLA target no breach 0%
99.0% up to target Tier 1 10%
95.0% up to 99.0% Tier 2 25%
Below 95.0% Tier 3 50%

SLA credits, answered.

Questions that come up when a real month falls short of a contracted SLA.

Is this the actual credit my contract owes? Not necessarily. This tool uses an illustrative, commonly seen tier structure. Your actual contract may use different thresholds, caps, or credit percentages — check the SLA schedule in your agreement for the exact terms.
Why are SLA credits usually a small percentage? Credits are typically capped as a percentage of fees paid, which is often far smaller than the customer's actual business impact from the outage — one reason credits alone rarely make a customer financially whole.
How does this relate to the SLA calculator? The SLA calculator shows how much downtime your target allows. This page shows what you owe once actual uptime falls short of it.
Should I use this for a customer-facing credit dispute? Use it to sanity-check a figure internally, then confirm the exact number against the contract's actual SLA credit schedule before communicating anything to the customer.

Credits are the visible cost. What's the real one?

SLA credits are contractual, not economic. See the full downtime cost calculator for the revenue and hidden-tax impact behind the breach.
