See the golf decision, not just the number.
GolfVectorLab is a free, browser-based reasoning system for recreational golf. Instead of a lone calculator, each tool works through a full decision: the answer, what it means for your game, the assumptions behind it, and the useful next question. Nothing you enter leaves your browser.
A connected way to think through golf decisions
Recreational golf is full of decisions that depend on each other: a fair handicap depends on the tee you play, a useful practice plan depends on knowing your real club distances, and a fair event depends on both. Most golf sites answer one of these in isolation. GolfVectorLab is built around a connected model instead, so an answer from one tool can carry into the next question without re-entering the same information.
Handicap & scoring
Course and playing handicap, stroke allocation, and format scoring, worked through with the tee and rules context that actually change the result.
Bag intelligence
A visual read on your carry distances and gaps, built from what you already know about your own bag, not a generic distance chart.
Round & practice planning
Condition-adjusted planning ranges and a practical practice session plan, with the uncertainty shown plainly rather than hidden behind a single number.
What GolfVectorLab is not
GolfVectorLab does not issue an official Handicap Index, post scores to a governing body, provide live GPS or course data, or give in-competition rules rulings. It explains published concepts and produces educational estimates. For an official handicap, tournament ruling, or current Rules of Golf question, use your golf association or the USGA and The R&A directly. See the disclaimer and responsible-use page for the full scope.
Every interactive engine on GolfVectorLab is built from a sourced, tested calculation method, so each result states its confidence and where it comes from. Read the methodology page for how that works, or the about page for the reasoning behind the project.
