About this calculator
Recovery point objective (RPO) is how much data you can afford to lose, measured in time since the last good backup; recovery time objective (RTO) is how long you can afford to be down before restoring service. Both translate directly into dollars, but organizations frequently set these targets aspirationally without ever confirming their actual backup infrastructure can hit them. This calculator estimates data-loss cost from RPO (based on the value of data or transactions generated per hour, since a 4-hour RPO means you could lose up to 4 hours of that value in a worst-case failure) and separately estimates downtime cost from RTO (based on revenue and labor cost per hour of outage), then flags the total exposure if a failure hit at the worst possible moment. The gap between stated RPO/RTO targets and what a tested restore actually achieves is one of the most common findings in disaster recovery audits, so pair this calculator's output with an actual timed restore test, not just the number written in your DR policy document.
Worked example
Using the values the calculator loads with:
Inputs
- Value of data/transactions generated per hour: 8000
- RPO (recovery point objective): 4
- Revenue generated per hour: 6000
- Recovery labor cost per hour: 1200
- RTO (recovery time objective): 8
- Actual tested restore time (if known): 18
Results
- Total worst-case exposure (stated RPO/RTO): $89,600
- Data-loss cost (from RPO): $32,000
- Downtime cost (from stated RTO): $57,600
- Downtime cost at actual tested restore time: $129,600
- Extra cost if actual restore exceeds RTO target: $72,000

FAQ
What's a typical RPO/RTO for a business-critical system?
Tier-1 transactional systems (payments, order processing) commonly target RPO under 15 minutes and RTO under 1-4 hours using continuous replication, while less critical internal systems might reasonably accept an RPO of 24 hours and RTO of 1-3 days using nightly backups, since tighter targets cost significantly more in infrastructure.
Why is there almost always a gap between stated RTO and actual restore time?
Stated RTO is usually written based on how long the backup copy job itself takes, while actual restore includes rebuilding infrastructure, restoring in the correct dependency order, validating data integrity, and testing before cutover, steps that are frequently skipped or underestimated until a real DR test or real incident exposes the true timeline.
How often should RPO/RTO targets actually be tested?
At minimum annually for critical systems, and ideally quarterly for anything supporting revenue-generating operations; a policy document stating a 4-hour RTO that was last actually tested three years ago should be treated as unverified, not as a real capability, especially after any significant infrastructure change.
Does cheaper, less frequent backup ever make sense?
Yes, for genuinely low-value or easily regenerated data, a longer RPO and RTO with cheaper cold backups is the economically correct choice; the point of this calculator is matching backup investment to the actual cost of loss for each system rather than applying the same aggressive (and expensive) targets to everything uniformly.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
