What it's costing you
Cut the failure rate
One lever: your failure rate. The saving is your failure bill today minus your bill at the target rate.
That failure rate is a guess. Prefactor measures it per run and attributes cost per agent. Dev tier: 25,000 free spans a month.
How the numbers are made
Failures per month
agents × runs/day × failure rate × 30How many bad runs reach production in a month.
Failure cost / month
failures/month × cost per failureWhat those bad runs cost once they land.
Manual checking / month
hours/week × hourly cost × 52 ÷ 12The human time spent watching output by hand.
What reliability recovers
failure cost now − failure cost at targetThe saving from one lever: a lower failure rate.
A model from your inputs, not a guarantee. Prefactor measures the failure rate instead of estimating it. Agent evaluation →
Frequently asked questions
Why is the number so large?
Failure cost compounds with volume. If the total looks too high, lower the failure rate or cost per failure to match what you see. The tool makes the compounding visible, not bigger.
What counts as the cost of a failure?
Whatever a bad output costs once it lands: an escalation, a reversal, an engineer cleaning up, a credit. Use a blended average. Unsure? Start with the loaded cost of the time to detect and fix one.
How is the saving worked out?
Your failure cost today minus your failure cost at the target rate. Same volume, same cost per failure, one lever.
Is this a Prefactor quote?
No. It is a model of your current cost of unreliability, from your own numbers, with no assumption about any tool.
