SE deal economics

What's it really going to cost?

Model total cost of ownership year by year — current state vs. proposed — with NPV, breakeven, and plain-English findings you can take into a deal review. A model, not a quote.

How it works

Four steps from blank page to deal-review-ready.

1

Enter the costs

Hardware, software, support, power, facilities, admin time, downtime risk, migration — for the current state and the proposal. Or load the demo to see it working.

2

Set the horizon

Pick 3, 5, or 7 years, add your cost of capital for NPV and an annual cost-uplift assumption. Watch the math update live.

3

Read the findings

Breakeven year, biggest cost drivers, recurring-opex share, power and staffing deltas — written as SE talking points, not spreadsheet cells.

4

Download the report

A standalone HTML report with the inputs, year-by-year tables, and findings. Save the project, export it, pick it back up next quarter.

FAQ

The fine print, up front.

Is this a quote?

No. This is a model, not a quote and not financial advice. It turns your cost assumptions into year-by-year TCO, NPV, and breakeven math. Every output is only as good as the inputs — validate hardware, licensing, and services pricing against real distributor quotes before anything customer-facing.

What goes in "downtime / risk cost"?

Your best estimate of the expected annual cost of outages and incidents on the current platform: lost productivity, SLA penalties, emergency support, revenue impact. It's the fuzziest input here — keep it conservative and say so in the room.

Why does it ask for a discount rate?

Money today is worth more than money in year 5. The discount rate (your cost of capital) converts future costs into net present value so you're comparing scenarios honestly. 8% is a common default; your finance team will have an opinion.

Can I compare more than two scenarios?

Two at a time: current state vs. one proposal. To compare two proposals, run the pair twice and keep both projects saved. Named saves, export, and import make that painless.

Where is my data stored?

In your browser's localStorage — on your machine, nowhere else. Named projects, autosave, and exports never leave your device. Close the tab on a shared machine and it's still there for the next user of that browser, so use Start over on shared machines.
