Cloud vs On-Premise TCO Estimator
Compare user-supplied costs over a chosen planning period without invented market prices.
Use figures from your own operation. The result is an indicative planning model, not a quotation or guarantee.
Your result
How this works
On-premise TCO combines initial hardware and licences with power and annual support. Cloud TCO combines setup with monthly subscription and connectivity over the same period.
Hypothetical worked example
A three-year comparison should include operating costs and migration—not only a server quote versus one month of cloud fees.
How to interpret the result
Use the output to compare scenarios and expose the assumptions that have the greatest effect. Validate the figures with process owners, finance and technical teams before making a purchasing decision.
Assumptions and limitations
- Inputs are supplied by you and are not verified by REVTEK.
- Taxes, financing, supplier terms and operational variation may be excluded.
- An estimate should be tested with measured data and sensitivity scenarios.
Common mistakes
- Using best-case assumptions only
- Ignoring support, adoption and exception handling
- Treating a calculated result as a supplier commitment
Practical next steps
- Confirm input figures with accountable owners.
- Run conservative, expected and optimistic scenarios.
- Document exclusions and review the estimate after implementation.
