Cloud vs. on-premises: 5-year cost calculator.
Plug in your own numbers to compare the real 5-year cost of running a server on-site versus moving to the cloud. For the categories of cost people tend to miss on both sides, see our Server vs. Cloud explainer.
On-premises (5-year total)
Cloud (5-year total)
For a real per-machine cloud VM cost instead of guessing, check the Azure Pricing Calculator or AWS Pricing Calculator for a VM sized like your current server, then plug that monthly number in above.

This compares the numbers you enter - it doesn't include harder-to-price factors like downtime risk, data-loss risk, or how well either option fits your specific applications. Read the explainer linked above before deciding based on cost alone.
