Cloud Migration ROI Calculator

Cloud Economics Tool

Cloud Migration ROI Calculator

Model the multi-year financial case for moving enterprise workloads to the cloud — discounted cash flow, payback period and net benefit, with sensitivity to the things that usually derail business cases: cost overruns, delays and price drift.

Strategy & horizon ▾
A rough relative price index, not live pricing. Adjust to your negotiated rates.
Used to discount future cash flows to today's money (NPV).
Upfront migration cost ▾
Engineering effort to move, test and cut over.
Annual running cost ▾
Hardware, hosting, maintenance & support you stop paying.
Lower utilisation favours cloud elasticity; higher steady load favours owned kit.
Quantified benefits / yr ▾
Avoided cost of outages from higher resilience.
Faster provisioning, less ops toil, quicker delivery.
Reduced breach risk, easier audit evidence.
New capability that drives sales. Leave at 0 if unproven.
Risk & sensitivity ▾
Delays push benefits later — and cost money while you wait.

Cumulative position over time

Discounted cash flow building to net present value. The line crossing zero is your payback point.

Annual costs vs. benefits

What you spend on the cloud each year against the legacy cost you avoid plus quantified benefits.

Cloud running cost Legacy avoided + benefits Net positive year

Strategy comparison all computed live

The same inputs run across all three migration approaches, so you can see the trade-off between upfront effort and long-term return.
