On-Call Incident Cost Model
00
Estimate the total monthly financial cost of on-call incident resolution.
NOTEAbout This Model
## Estimate the total monthly financial cost of on-call incident resolution. This model estimates **Total On Call Cost** based on uncertain inputs: Alert Volume, MTTR Hours. Run the simulation to see the distribution of possible outcomes.
VARIABLEAlert Volume
poisson(55)
Number of alerts per month.
alert_volume
VARIABLEMTTR Hours
triangular(0.5, 2.25, 4)
Time in hours spent per incident. Note: Units changed from 'rate' to 'unitless' to allow values > 1 but retain MtTR logic.
mttr_hours
FORMULATotal Resolution Hours
alert_volume * mttr_hours
Total labor hours required to resolve all incidents.
total_resolution_hours
FORMULATotal On Call Cost
total_resolution_hours * hourly_labor_rate
Total financial cost based on hourly labor rates ($500/hr).
total_on_call_cost
OUTPUTTotal On Call Cost
total_on_call_cost
Total cost of on-call incident response including labor and downtime. High values suggest investing in reliability engineering or reducing MTTR would have strong ROI.
CONSTANTHourly Labor Rate
500
Fully-loaded cost per hour of on-call engineer time.

What is Carlo?
Carlo is a visual tool for Monte Carlo simulation. Model uncertainty by dragging probability distributions, connecting them visually, and running thousands of scenarios instantly.
