Know in minutes
whether a project is worth it.
Calculus turns project ideas into reliable numbers. NPV, ROI, break-even and financing scenarios, before your team commits time and budget.
The Problem
Too many projects are still
evaluated in Excel.
Teams rebuild the same model in Excel over and over. Formulas get adjusted, versions multiply and stakeholders lose track of the logic.
Repetitive model work
Teams rebuild similar cashflow models from scratch instead of getting straight to the analysis.
Errors and version chaos
Small formula changes quickly introduce errors. Multiple versions of the same calculation start to circulate.
Hard to follow
Stakeholders see the result but not the logic behind it. That slows down fast and confident decisions.
What Calculus does
Everything you need for a
well-founded project decision.
From the first cost estimate to the financing structure: Calculus maps the entire evaluation process in one clear structure.
Input
Model revenue and costs
One-time and recurring costs as well as revenue items are entered directly in the project view. No formulas needed.
KPIs
NPV, ROI, margin and break-even
All key profitability metrics are calculated automatically and visible immediately, including NPV project and NPV equity.
Plan vs. actuals
Record and compare actuals
Actual costs and revenues are entered in the table view. Budget vs. actual costs and the profit waterfall update automatically.
AI assistant
Query project data instead of searching
The built-in AI chat reads your project data from Calculus and Planner and answers specific questions in plain language. No manual exports, no menu navigation.
Financing
Add debt financing without
rebuilding the model.
Calculus shows immediately how financing shares affect cashflow, NPV and return. Interest rate, term and loan type are adjustable directly.
