Decision-Making Calculators & Tools
Free, practical tools for thinking through a choice — weigh options against your priorities, put numbers on uncertainty and time, minimise regret, and plan when to decide.
Weighted Decision Matrix
Score options against weighted criteria and get a ranked shortlist with a clear winner. The best all-round choice for comparing several options on multiple factors.
Weighted Pros & Cons Scorer
A pros-and-cons list with teeth: weight each point 1–5 and see which way you actually lean, with a lean-yes, lean-no, or toss-up verdict.
Expected Value Calculator
Put a number on an uncertain choice. Enter outcomes, probabilities, and payoffs to get the probability-weighted average, plus the best and worst cases.
Cost-Benefit Analyzer
Weigh costs and benefits that play out over time. Returns net present value, benefit-cost ratio, and payback period, with proper time discounting.
Regret Minimization Scorer
Choose defensively when you can't put odds on the future. Finds the option with the smallest worst-case regret — the minimax-regret criterion.
Decision Deadline & Timing Planner
Decide when to decide. Turns a deadline, the stakes, and reversibility into a deliberation window and a firm 'decide by' date.
