Regret Minimisation Framework Calculator
Weigh a major financial decision by future regret in both directions.
Use Jeff Bezos regret minimisation framework to evaluate major financial decisions. Weigh regret of action vs inaction at a future age.
What this tool does
Regret minimisation evaluates a major financial decision by imagining yourself at a future age and comparing how much you'd regret taking action versus not taking action. You assign regret scores from 0 to 10 for each path—doing the thing and not doing it—then specify your future age reference point. The calculator returns which direction produces less regret and shows the net regret difference between the two choices. The result depends most heavily on how differently you score the two regret scenarios; if both scores are similar, the framework suggests the decision is finely balanced. This approach works for decisions like career changes, major purchases, or lifestyle shifts where long-term emotional satisfaction matters. The calculator is for personal reflection only and doesn't account for financial constraints, external circumstances, or how regret itself changes over time.

The regret minimisation framework, popularised by Jeff Bezos, asks a specific question when facing major decisions: "At age 80, will I regret doing this, or will I regret not doing this?" It's a deliberate tool for decisions where standard cost-benefit analysis produces unclear answers — especially life decisions with financial components (starting a business, taking a sabbatical, making a major investment, relocating).
The framework works because most people undervalue future regret about inaction compared to present risk of action. At the decision moment, action feels risky (loss aversion). At age 80, inaction regrets typically dominate — the things not attempted, the opportunities passed, the risks avoided. Bezos's own framing: "I knew that when I was 80 I was not going to regret having tried this. I knew that if I failed I wouldn't regret that."
The calculator formalises this. Score your estimated regret at a future age for taking the action (scale 0-10). Score your estimated regret for not taking it (same scale). The difference indicates which choice minimises future regret. This doesn't replace financial analysis — it supplements it when the financial numbers are ambiguous.
How to use it
Think of a specific major financial decision you're considering. Imagine yourself at a specific future age (70, 80, or whatever feels meaningful). Score 0-10 your estimated regret if you do it and it fails. Score 0-10 your estimated regret if you don't do it. The direction of the net indicates which path minimises long-term regret.
What the result means
If regret-of-not-doing exceeds regret-of-doing, the framework suggests taking the action — the worst outcome of trying is typically less painful than the chronic regret of not trying. If regret-of-doing exceeds regret-of-not-doing, caution is likely correct. Close scores indicate the regret framework isn't decisive, and other factors should dominate.

Sources & Methodology
Methodology
The calculator applies a regret-minimization framework by computing the net regret as the difference between two scalar inputs: regret experienced from inaction minus regret from action. Users rate both scenarios on a 0–10 scale, anchored to a specified future age reference point. A positive net value suggests that action carries lower regret; a negative value suggests inaction carries lower regret; values near zero indicate the framework offers limited decisiveness for that particular choice. The model treats regret scores as stable, cardinal estimates and assumes no change in circumstances, preferences, or external conditions between the present and the future reference age. It does not model emotional intensity drift, probability-weighting of outcomes, financial consequences, social factors, or the psychological accuracy of anticipatory regret judgments.
