Calculadora de Caso (Expected Value)
Use this calculator to estimate whether a project, legal claim, negotiation, or investment case is financially worth pursuing.
What is this “calculadora caso” and why use it?
Most people make case decisions emotionally: “This feels important, so I should do it,” or “This sounds risky, so I should avoid it.” A better approach is to combine clarity + numbers. That is exactly what this calculadora caso does.
It estimates the expected value of a case by blending possible upside, costs, time, and probability of success. You can use it for many real-life scenarios:
- Legal or insurance claims
- Business negotiations
- Freelance payment disputes
- New side-hustle opportunities
- Product launches or pilot programs
How the calculator works
The logic is intentionally simple and transparent:
- Potential gross value = monthly benefit × months
- Expected gross value = potential gross value × probability of success
- Total costs = upfront cost + (monthly cost × months)
- Expected net value = expected gross value − total costs
- ROI = expected net value ÷ total costs
If expected net value is positive, your case may be financially attractive. If it is negative, your current assumptions suggest caution.
Break-even insight
A useful feature in this tool is the estimated break-even month. It answers: “How long until this case has paid back its upfront cost under my probability-adjusted assumptions?”
Quick example: the coffee habit analogy
Suppose your “case” is changing one habit and investing the savings:
- Monthly benefit: $150 saved/invested
- Upfront cost: $0
- Monthly cost: $0
- Time horizon: 24 months
- Success probability: 80%
The calculator won’t predict markets, but it will show your probability-adjusted upside and keep your decision grounded in realistic assumptions. This is the same mindset behind financial behavior change: small inputs, repeated over time, can produce meaningful outcomes.
How to use this calculator well
1) Be honest about probability
Overconfidence destroys planning. If you are unsure, run three scenarios: conservative, base case, and optimistic.
2) Include hidden costs
Time, admin work, emotional load, and opportunity cost matter. If possible, convert them into monthly cost estimates.
3) Compare alternatives
The best use of a case calculator is not “yes/no in isolation.” It is “which option has the best risk-adjusted return?”
4) Recalculate as facts change
Early assumptions are usually wrong. Update inputs when new evidence appears and make your next decision from current data.
Common mistakes to avoid
- Using a 100% success probability “because I’m sure”
- Ignoring monthly drag costs
- Using too short a time horizon
- Confusing revenue with actual net value
- Treating this as a guarantee instead of a decision aid
Final takeaway
A good decision is not just about confidence; it is about expected value. This calculadora caso gives you a practical framework: quantify upside, subtract true costs, apply realistic probability, and choose with discipline.
Use it before committing money, time, or attention. Better inputs lead to better decisions.
