What it means
A service credit is an amount credited to a customer's account when a supplier misses a defined service commitment, subject to a contract or service level agreement. The failure might involve uptime, response time or another measured target.
A credit is often applied against later fees rather than paid in cash, so it is a conditional remedy. A good service level agreement defines the covered service, target, measurement period and what counts as downtime.
For a cloud product, '99.9% availability' is not enough by itself: does maintenance count, are failures in a customer's own configuration excluded, and does measurement use the supplier's logs or an independent monitor? The answers change whether a credit is due, so a customer should read definitions before relying on the headline percentage.
Credits are commonly tiered by severity. AWS's Amazon EC2 agreement, for example, sets different percentages for availability bands and calculates them from the affected service's eligible monthly bill, subject to its detailed terms, and Google Cloud's Compute Engine agreement also uses tiered credits against future bills.
These are specific product agreements, not standard rates for every service, so the actual formula and eligibility should be checked in the specific contract. An illustrative calculation is $20,000 in eligible monthly fees multiplied by an agreed 10% credit rate, yielding a $2,000 credit.
If only one service or region was affected, the eligible fee base could be much smaller than the customer's whole invoice, and a cap, tax treatment or overlapping incident rule might also reduce the amount. Never compute a claim using the total account spend without reading the SLA's definitions.
A claim process can be a condition of payment. AWS asks customers to submit a case with specified information by a deadline under its agreement, and Google Cloud's published terms likewise describe request requirements and deadlines for particular services.
A supplier may need incident timestamps, affected users and evidence, so assign someone to review outages promptly so that a valid claim is not missed because the operations team assumed the finance team would submit it. A service credit should be compared with the business impact, not mistaken for full insurance, since a two-hour outage can cost a retailer more than the hosting fee for a month.
Some SLAs make credits the customer's sole and exclusive remedy for service-level failure, as Google's published agreement illustrates, while other contracts preserve separate rights for breach, gross negligence or other events, so the clause and governing law decide, not the label. Suppliers should price and monitor commitments they can actually meet, because a promise of nearly perfect uptime across a system with external dependencies can create disputes about responsibility, and customers should check whether the service must remain active to use a credit, since a future-invoice-only remedy has little value after termination, whether credits are capped at a month's fee, and whether repeated failures give termination and migration rights that matter more than a single credit.
In practice
Real-world examples.
Example
A cloud provider applies a percentage credit to the eligible service fee after a qualifying outage. The credit appears as a reduction on the next invoice rather than as a cash payment.
Example
A customer submits timestamps and impact evidence before the SLA claim deadline. Its operations team records the outage start and end from its own monitor, and finance files the claim within the contractual window.
Example
A buyer checks whether repeated failures permit termination as well as credits. The contract lets it exit after three qualifying breaches in a year, which matters more to the buyer than the small monthly credit.
Formula
Calculation
Service credit = eligible affected-service fee x contractual credit percentage, subject to caps and conditions.
Worked example. A fictional customer pays $60,000 a month across three services, but only the hosting service, billed at $20,000, was affected by a qualifying outage. The agreement gives a 10% credit for that availability band.
- Credit = $20,000 x 10% = $2,000.
- If the credit had wrongly been applied to total account spend, it would be $60,000 x 10% = $6,000, which overstates the claim by $4,000.
- If the contract caps credits at 25% of the affected fee, the cap is $20,000 x 25% = $5,000, so the $2,000 credit stands.
Total account spend may not be the eligible base, so always read the SLA's definitions before submitting a claim.Case study
Seen in the real world.
This illustrative and entirely fictional case follows Horizon Retail, an invented online retailer that suffers a hosting outage. Its old agreement lacks a clear credit schedule, so the dispute with the supplier drags on without a defined remedy. At renewal it negotiates a measurable target, an eligible fee base and a claim process. A later documented incident leads to a credit under the new terms, applied to the following invoice. The credit does not guarantee improved uptime or compensate every loss, which is why the retailer also negotiates termination rights for repeated failures.
Watch out
Common mistakes.
- Assuming every outage triggers an automatic cash refund.
- Calculating the credit on the entire invoice rather than the eligible fee base.
- Missing the contract's claim deadline or ignoring exclusive-remedy terms.
Questions

What is a service credit?
A contractual fee credit for a qualifying service-level failure.
Where is it set out?
Usually in an SLA or service contract defining targets, measurement and claim terms.
Are credits capped?
Often, but the cap and the interaction with other remedies depend on the specific agreement.
