pm-calculators
Estimate the ROI, payback, and NPV of an investment, project, or purchase. Use when asked to calculate ROI, build a business case, justify a purchase/initiative, work out payback period, or compare options by return. Produces a computed ROI summary (net benefit, ROI %, payback, simple NPV) with the assumptions made explicit and a sensitivity note, so a business case is defensible.
What to give it
▸Costs — upfront cost, and any ongoing/recurring cost (per period).
▸Benefits — the expected gain per period (revenue uplift, cost saved, time saved × loaded rate). Quantify; if it's an estimate, say so.
▸Time horizon — over how many periods to evaluate (e.g. 3 years).
▸Discount rate — for NPV (default ~10%); state it.
✅ The bar it holds itself to
Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.
✓Costs include recurring/ongoing, not just upfront
✓NPV is computed (time value of money), not just raw ROI
✓Benefits are given as a range (conservative/expected/optimistic), not a single optimistic point
✓Every assumption is listed explicitly
✓A sensitivity note names the assumption the verdict hinges on and its flip point
⚠️ What it refuses to do
Do not ignore ongoing costs — a low upfront, high-recurring option can lose to a pricier one-time buy
Do not present a single benefit number as fact — it's the softest input; give a range and flag it
Do not skip discounting for multi-year cases — $1 in year 3 isn't $1 today
Do not bury the assumptions — a business case is only as credible as its stated inputs
Do not omit payback — a great 5-year ROI with a 4-year payback may still be too slow to fund
