Move the sliders and watch a real SaaS financial model recalculate instantly

This runs real financial logic, the same engine that powers the full app.

Generic templates don't fit

SaaS metrics shoved into a marketplace model. E-commerce revenue logic in a services template. Your projections are wrong before you start.

$3K for a model you can't change

Hire a consultant, wait 2 weeks, get a locked spreadsheet. Need to update a single assumption? That'll be another invoice.

Spreadsheets with no guardrails

Build from scratch, pray the formulas are right, and hope your churn assumption isn't 10x industry average. No one checks.

ModelForge solves all three.

How it works

Pick your business model

SaaS, E-commerce, Marketplace, Services, or Usage-Based. Each has its own financial engine.

2

Adjust your assumptions

50+ sliders with industry benchmarks. Real-time guardrails warn you when values are outside norms.

3

Export and present

Download Excel with real formulas, share a link, or export a branded PDF report.
