MTTR Calculator

Translate your mean time to respond into annual financial exposure — and model the saving from cutting it by 70%.

  • Uses IBM Cost of a Data Breach benchmark data
  • Models incident cost per hour of response time
  • Projects annual exposure at current and target MTTR
  • Shows saving at 70% and 90% MTTR reduction scenarios

How this tool works

1

Enter your current MTTR

Input your mean time to respond in hours. If you measure in days, multiply by 24. Use your last quarterly MTTR report.

2

Set your incident frequency and average cost

Enter how many incidents you contain per month and your estimated average incident cost including analyst time and remediation.

3

See annual cost of slow response

The calculator models how each hour of MTTR adds to your annual incident exposure, and what a 70% MTTR reduction would save.

What to do with the result

Turn MTTR into dollars

Present the annual MTTR cost to your board as a concrete security investment justification.

Set a reduction target

Use industry benchmarks to set a realistic 90-day MTTR reduction goal and track progress against it.

Correlate with breaches

Layer in breach probability data to show how faster response translates to reduced breach likelihood.

MTTR calculator: frequently asked questions

What is a good MTTR benchmark for enterprise security teams?

Industry median MTTR is 16 hours according to IBM's Cost of a Data Breach report. Top-quartile teams with automation achieve under 3 hours. ManySignal customers average 23 minutes for contained incidents after deployment.

Does the calculator account for the full incident lifecycle?

The MTTR in this calculator covers detection to containment. It does not include recovery and eradication time, which are captured in the Incident Cost Calculator. Toggle 'Full lifecycle mode' to include remediation hours.

How does ManySignal reduce MTTR so dramatically?

Three factors: the triage agent issues a verdict in under 4 minutes on average (vs 45-90 minutes manual); the investigation agent reconstructs attack chains automatically; and response workflows execute containment actions with one approval click.

What cost per incident hour does the calculator assume?

The default is $15,400 per hour of incident duration, sourced from IBM's 2024 Cost of a Data Breach report (average US enterprise). You can override this with your own figure based on revenue at risk, regulatory exposure, or contractual SLA penalties.

Can I use this to quantify cyber insurance premium reduction?

Some insurers offer premium reductions for documented MTTR improvements and automated response capabilities. The calculator output, combined with ManySignal's audit trail evidence, is suitable for insurance underwriter submissions.

How do I measure my current MTTR accurately?

MTTR should be measured from the timestamp of first detection (SIEM alert or threat intelligence hit) to the timestamp of the first containment action (account disabled, network block applied, etc.). Avoid using email notification time as the start point.

What does a 70% MTTR reduction assume?

70% is ManySignal's median MTTR reduction across enterprise deployments at the 90-day mark. Some customers achieve 90%+ reduction; highly manual environments with no existing SOAR capability tend to show the largest gains.

Does dwell time factor into this calculation?

The calculator focuses on response time after detection. If you want to model the cost of dwell time (attacker present before detection), use the 'Include pre-detection phase' toggle which adds your average detection lag to the total exposure window.
