SaaS Startup Financial Model — 5-Year Monthly Plan (Excel Template, Investor-Ready)

A complete, investor-ready financial model for early-stage SaaS startups — built the way analysts actually build them: one Assumptions tab drives everything, and every output cell is a live Excel formula (zero hardcoded numbers).

Enter your launch MRR, ARPU, customer adds, churn, CAC, gross margin, hiring plan and funding rounds. The model instantly produces a 60-month customer and MRR/ARR build, a monthly P&L with annual summary, a simplified indirect cash flow with DSO/DPO working capital and a minimum-cash alert, and a Summary Dashboard with the metrics investors ask for first: LTV/CAC, CAC payback, burn multiple, EBITDA margin and runway.

Six tabs: Cover, Assumptions, Revenue Build, P&L, Cash Flow, Summary Dashboard — with a 12-role headcount plan (departments, salaries, start months and benefits load flowing automatically to S&M, R&D and G&A), a funding round schedule (Seed, Series A, optional Series B) wired straight into the cash flow, automatic annual summaries for Years 1 through 5, and three built-in charts: Revenue vs EBITDA, Ending ARR and Ending Cash.Ships pre-loaded with a coherent default scenario (~$5.9M ARR by Year 5, near-breakeven in Year 4) so you can see exactly how a fundable plan hangs together — then swap in your own numbers. Ideal for founders preparing a seed or Series A raise, accelerator applications and board planning. Blue-input / black-formula convention, clean formatting, no macros, works in Excel and LibreOffice.
