I built BCZ because I was tired of rebuilding the same DCF models in Excel for every new project. Now I just plug in the numbers and get a full analysis with a PowerPoint deck in minutes. Would love your feedback — what KPIs or features would make this even more useful for you?

The Problem

Every investment decision starts with a business case. But building one usually means wrestling with complex Excel spreadsheets, debugging formulas, manually formatting slides, and hoping nothing breaks when you change an assumption. For most teams, this process takes days — and the result is still error-prone and hard to present.

The Solution

BCZ is a free, browser-based business case calculator that turns your financial assumptions into a complete investment analysis in minutes. No spreadsheet skills required. No account needed. No data ever leaves your browser.

Enter your capital expenditures, revenue streams, and operating costs — BCZ instantly calculates all key investment KPIs: Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period, Return on Investment (ROI), and Profitability Index. Every metric updates in real time as you adjust your inputs.

What Makes BCZ Different

Full Financial Model, Not Just a Calculator BCZ doesn't just spit out a single number. It generates a complete Profit & Loss statement with EBITDA, EBIT, depreciation, and net income projections across your entire planning horizon. It also produces a detailed Cash Flow analysis showing free cash flow and cumulative cash flow year by year.

Interactive Sensitivity Analysis Uncertain about your assumptions? Use built-in sliders to adjust individual revenue streams, cost items, and CAPEX positions. Watch NPV, IRR, and payback update instantly — so you can stress-test your case before presenting it.

One-Click PowerPoint Export Turn your entire analysis into a professional, board-ready 7-slide PowerPoint deck with a single click. KPI dashboards, charts, tables, and sensitivity results — all formatted and ready for your next investment committee or stakeholder meeting. No copy-pasting, no manual formatting.
