How to Use This Calculator

Enter Annual Revenue and your target Recovery Time Objective (RTO) and Recovery Point Objective (RPO) in hours.
Input Primary Infrastructure Monthly Cost to establish the baseline.
Set Expected Outages per Year and Average Outage Duration (hours) to model downtime risk.
Review DR Monthly Cost, Annual Downtime Cost without DR, and Net Benefit to justify the investment.
Compare RPO/RTO tiers to find the cost-optimal DR configuration.

How the result changes with Recovery Time Objective (hours)

Recovery Time Objective (hours)	DR monthly cost	DR annual cost
17	$2,300.00	$27,600.00
59	$1,100.00	$13,200.00
109	$1,100.00	$13,200.00
151	$1,100.00	$13,200.00

Annual revenue ($): Total annual revenue that depends on system availability.
Recovery Time Objective (hours): Maximum acceptable downtime. <1hr = hot standby, 1-4hr = warm, 4-24hr = cold.
Recovery Point Objective (hours): Maximum acceptable data loss in hours. 0 = zero data loss (continuous replication).
Primary infra monthly cost ($): Current monthly spend on primary production infrastructure.
Expected outages per year: Historical or expected number of major outages per year.
Avg outage duration (hours): Average length of an outage without DR in place.

DR monthly cost: Total monthly cost for DR infrastructure + replication.
DR annual cost: Total yearly DR spend.
Annual downtime cost (no DR): Estimated revenue loss from outages without DR.
Net annual benefit: Avoided downtime cost minus DR spend (positive = DR pays for itself).
DR ROI %: Return on investment for DR spend.
DR infra cost / month: Monthly cost for standby infrastructure.
Replication cost / month: Monthly cost for data replication to DR site.
Max data loss value ($): Dollar value of data at risk during one RPO window.

Identify Input Parameters
4 parameters
Annual revenue ($) = 5000000, Recovery Time Objective (hours) = 4, Recovery Point Objective (hours) = 1, Primary infra monthly cost ($) = 10000 = 6 input(s) provided
Calculate DR monthly cost
DR monthly cost = drInfraMonthlyCost + replicationMonthly
2300 = $2,300
Calculate DR annual cost
DR annual cost = totalDrMonthlyCost * 12
27600 = $27,600
Calculate Annual downtime cost
Annual downtime cost = downtimeCostPerIncident * outagesPerYear
3424.66 = $3,424.66
Calculate Net annual benefit
Net annual benefit = annualDowntimeCost - totalDrAnnualCost
-24175.34 = $-24,175.34
