5	How to use it
6	Step 1	Open the Inputs tab. Fill every yellow cell with blue text using your own numbers. Sample values are pre-filled so you can see the format. Overwrite them.
7	Step 2	Open the Summary tab. It shows the 24-month cost of each path, the payback month, and a plain-language verdict.
8	Step 3	Work through the contract checklist at the bottom of Summary. Any 'No' or 'Unsure' can change the cost of leaving.
9	Step 4	The Model tab is the month-by-month calculation. You should not need to edit it.
10	Legend
11	Yellow cell, blue text	Input. Edit these.
12	Black text	Formula. Do not overwrite.
13	Currency	Shown as $. Enter any single currency consistently; the labels are cosmetic.
14	Read this before trusting the result
15	Sample values	The pre-filled numbers are illustrative only, matching the worked example in our blog post. They are not benchmarks and not a quote.
16	What it leaves out	Strategic factors such as vendor acquisition risk, regulatory deadlines and lost buyers are only captured if you price them into the delay and change-request inputs.
17	Want a second opinion?	Send us your completed sheet and setup at techaroha.com/contact for an independent assessment before any rebuild is proposed. If staying is the right call, we will say so.
