A free, no-signup tool that does the maths most teams get wrong — instantly and privately.
Every week, IT managers, procurement officers, and operations teams spend hours manually calculating SLA breach penalties — cross-referencing contract PDFs, building Excel formulas, and second-guessing their arithmetic before sending a claim.
Most of them get it wrong. Either they undercount the downtime overage hours, miss the credit cap clause, or apply the wrong penalty tier. Vendors know this, and they count on it.
SLABreachCalculator.site was built to close that gap. Input your contract parameters, enter the actual performance data, and get the precise, defensible penalty figure in seconds — no spreadsheet, no signup, no data stored anywhere.
The calculator handles the three most common SLA breach scenarios found in commercial IT and service contracts:
Uptime / Availability — computes excess downtime hours vs. contracted %, applies flat, percentage, or tiered penalty structures, and enforces credit caps.
Response Time — calculates penalty across multiple breached incidents with per-incident rates and max caps.
Delivery / Milestone — calculates late penalties by day, week, flat fee, or contract percentage with grace period support.
All calculations happen entirely in your browser. No data is ever sent to a server, logged, or stored.
No account, no form submission, no waiting. Enter your numbers and get your answer immediately.
Calculations follow standard SLA penalty formulas used in enterprise cloud and managed service contracts.
Free forever, works on any device, no ads, no paywalls. Built to serve everyone from startups to enterprises.
SLABreachCalculator.site provides estimates based on the inputs you supply. The results are a starting point — a defensible, clearly-documented number to bring to a negotiation or formal claim process.
This tool is not a substitute for legal advice. For high-value disputes, breach of government contracts, or cases where the penalty language is ambiguous, always involve your legal or procurement team before submitting a formal claim.
