Compound decay
contacts × [1 − (1 − annual rate)^(months ÷ 12)] avoids counting the same record as newly decayed more than once.

How the calculation works
Health and modeled cost
Healthy records equal total minus decayed records. Cost equals decayed records multiplied by your documented cost per bad record.
Verification scenario
Full cleansing cycles multiply total records by verification cost. Residual cost applies the uncaught share of decay.
Savings and ROI
Net savings compare inaction with verification plus residual cost. ROI divides net savings by verification spend.
Frequently asked questions
What is CRM data decay?
The gradual loss of record accuracy or usefulness as contact details, roles, companies, preferences, and other attributes change.
Does Arches CRM assume a standard rate?
No. The calculator uses the rate you enter. Industry is report context only.
Why compound decay?
It applies the rate to records that remain healthy and avoids repeatedly counting the same record.
What is expected catch rate?
The share of modeled decay you assume verification will identify or prevent from creating the selected cost. It is not a guarantee.
Must I submit a form to see results?
No. The form unlocks only the PDF report.
