ROI memo
A memo justifying a spend — investment, expected return, payback period, downside scenario.
For when you need to spend $X on a tool / hire / project and explain why.
The prompt
Copy this into ChatGPT, Claude, Gemini or any assistant you already use — then paste your own investment + expected return underneath it.
Write an ROI memo. Sections:
**Proposed spend** (what + how much)
**Expected outcome** (the benefit, with a number)
**Math** (show how the return is calculated, with assumptions)
**Payback period** (months to break even)
**Downside scenario** (what if assumptions are 50% wrong)
**Recommendation** + decision criteria
Rules:
- Make every assumption explicit.
- No round-number gut-feel returns ("we'll 10x revenue") without basis.Example input
Spend ₹6L/mo for a senior growth marketer. Expected: 30% increase in inbound demo bookings within 6 months.
