How we calculate

The calculation is based on the formula Monte Carlo, the data observability company, published for its own calculator, and on its surveys. Anything that is our own assumption is marked as one.

LineCalculationSource
Incidents a yearTables × 0.07.Monte Carlo 2022: about 70 incidents a year per 1,000 tables.
Downtime hoursIncidents × hours each: 19 without monitoring, 12 with manual checks, 6 with automated monitoring. Up to 8,760 hours a year.Monte Carlo survey, 2023: 15 hours to resolve and about 4 to detect. 12 and 6: our assumption.
Engineering timeEngineers × yearly cost × share of time on incidents: 40%, 25% or 12%, but never more than 3 engineer-hours per hour of downtime. Yearly cost: $112K in dollars or euros, ₪535K in shekels.Monte Carlo 2022: data engineers spend 40% of their time on bad data. $112K: Monte Carlo's $62 an hour × 1,804 hours. ₪535K: Israel's average high-tech wage (CBS 2026) with employer costs. 25%, 12% and 3 engineer-hours per downtime hour: our assumption.
Revenue impactRevenue per hour × dependency on data (5%, 10% or 15%) × downtime hours, up to $15M.The formula, levels and cap of Monte Carlo's calculator.
CapThe yearly cost never exceeds 15% of revenue. When the cap applies, the lines shrink in proportion.Redman, MIT Sloan Management Review 2017: poor data quality costs 15%-25% of revenue.
Savings with monitoringToday's cost minus the cost with automated monitoring.The calculation itself.

Each answer range is calculated at its midpoint. Exchange rate: $1 = ₪3.6.

Questions

What is a data incident?

Any time data is wrong, missing or stale: a table that didn't load, a field that changed without notice, duplicates. The incident itself is quiet; the damage comes when someone decides on a wrong number.

We don't have a data warehouse. Is this relevant?

Less so. The data value calculator fits better, and it will also show whether it's time for a central warehouse.

How does automated monitoring work?

Tools that keep checking whether tables updated on time, whether volumes look normal and whether the schema changed, and alert you before a user runs into the problem.
