RTO and RPO Calculator: Estimate Your Backup Recovery Time

By the Assured Cyber Protection team · Updated 2026 · Reviewed

Two numbers decide how badly a ransomware hit or a failed server hurts you. Your RPO is how much data you could lose, set by how often you back up. Your RTO is how long you are down while you restore, set by how much data you hold and how fast you can pull it back. Cyber insurers now ask for both, so it pays to know yours.

Your recovery figures

Sets your worst-case data loss (RPO).
The systems and files you must bring back to trade.
Local backup can be 500 to 1000+; a cloud restore is capped by your download line.
Spotting the incident, deciding, and rebuilding clean hardware before the restore starts.

Cost of being down

The restore time here assumes the copy actually works and is not itself encrypted, which is why insurers reward offline or immutable backups and a tested restore. If your RPO or RTO looks worse than you can live with, the fixes are usually more frequent backups (lower RPO) and a faster or more local restore path such as a warm standby (lower RTO).
