Everything you'd normally have to ask a salesperson
Very close to what you'll actually be quoted. The calculation uses the same audit day guidelines that accredited certification bodies are required to follow worldwide. Local day rates are based on real market data for your region. Your final quote may vary slightly depending on the provider, but this gives you a solid, honest baseline before any conversations.
The calculator currently provides estimates for ISO 9001, ISO 27001, ISO 45001, ISO 14001 and other ISO standards. These are the most commonly requested standards and cover a wide range of industries. The underlying calculation method is the unique across all standards, with adjustments for specific audit requirements.
Stage 1 is a documentation review — typically one day — where the certification body checks that your management system is ready for assessment. Stage 2 is the full audit of your actual operations, which is usually 2–4 days depending on your size. Your estimate breaks both out separately, plus annual surveillance costs for years 2 and 3.
Certification bodies determine how many audit days your organisation requires based on the number of people in scope — the more staff, the more time it takes to audit your processes. This is set by international certification body guidelines, not something providers make up. Alex uses your employee count to calculate the right number of audit days for your situation.
No. This estimate covers certification body costs only (the audits). It does not include any fees for an ISO consultant who might help you prepare. Many businesses hire a consultant to build their management system before the audit. If you want to compare quotes for both certification and consulting, CertBetter can match you with verified providers for a full picture.
Use it as your benchmark. When you then request quotes from certification bodies, you'll know immediately whether you're being quoted fairly. If you'd like to skip that process entirely, CertBetter can get you up to 3 competing quotes from verified providers within 24 hours — no calls required on your end.
Free and instant. No one will call you or ask you to sign anything.
