It depends heavily on scope, but a useful benchmark is:
If you want to access to 250+ pre-built templates, here are all my public financial models.
| Model type | Typical time from scratch |
|---|---|
Simple budget / forecast model | 2–6 hours |
Basic 3-statement financial model | 1–2 days |
Detailed operating model for a company | 2–5 days |
SaaS / subscription model with cohorts, churn, CAC, LTV | 3–7 days |
Project finance / real estate development model | 3–10 days |
| LBO or M&A model | 1–4 days, depending on complexity |
| Board/investor-ready model with scenarios, charts, assumptions, outputs | 1–2+ weeks |
A clean, investor-ready model usually takes longer than people expect because the actual spreadsheet construction is only part of the work. Time also goes into gathering assumptions, structuring revenue and cost drivers, checking formulas, making outputs readable, building scenarios, and stress-testing the model.
As a rough rule:
Fast but basic: same day
Useful and decision-ready: 2–5 days
Polished and defensible: 1–2 weeks
For one company, a solid model from scratch usually means a 3-statement model with assumptions, revenue build, expense build, hiring plan, capex/debt if needed, scenarios, KPIs, and summary outputs. For that, I’d budget 3–5 working days if the inputs are reasonably available.
The timing above generally fits my own experiences. You can hire me for custom financial modeling work.
