About Valuation Guru
Valuation Guru provides professional-grade financial calculators and resources for investors, analysts, and finance professionals. Our flagship tool is the Valuation Guru, a free online utility for computing Internal Rate of Return, Multiple on Invested Capital (MOIC), and Total Value to Paid-In (TVPI).
Our Mission
We believe that sophisticated financial analysis should be accessible to everyone. Whether you're a seasoned private equity professional evaluating a leveraged buyout, a venture capitalist assessing portfolio company returns, or an individual investor analyzing a real estate opportunity, you need reliable tools that produce accurate results quickly.
Our IRR calculator was built to fill a gap: most free online IRR calculators are either overly simplistic (ignoring date-based XIRR calculations) or require data submission to external servers. Our calculator runs entirely in your browser, uses proper Newton-Raphson iteration for accurate XIRR computation, and respects your privacy by never transmitting your data.
What We Offer
- IRR / XIRR Calculator: Compute date-sensitive internal rate of return using the Newton-Raphson method with multiple convergence attempts for reliable results.
- MOIC Calculator: Automatically calculates the Multiple on Invested Capital alongside IRR.
- TVPI Calculator: Total Value to Paid-In ratio for comprehensive investment analysis.
- Multi-Format Export: Every calculation can be exported in three formats — copy a formatted summary to clipboard, download a CSV for Excel or Google Sheets, or paste directly into Excel with live
=XIRR()formulas intact. No rekeying, no formatting cleanup. - Multi-Currency: Over 100 currencies supported with a searchable selector. All results, exports, and labels update instantly to match your chosen currency.
- Educational Resources: Detailed guides explaining IRR, how it's calculated, and how it compares to other metrics like ROI.
Our Technology
The calculator uses pure HTML, CSS, and JavaScript with no external dependencies. The Newton-Raphson algorithm is implemented with multiple fallback starting points to handle challenging cash flow patterns. All calculations are performed client-side — no data ever leaves your browser. This means the tool is fast, private, and works offline once loaded.
The multi-format export system generates properly structured CSV files, tab-separated Excel-ready blocks with live formulas, and plain-text summaries — all client-side, all instant, all free.
