The scoring formula (simple, but powerful)

A trade‑off is just a weighted comparison. This tool uses two layers: importance weights (what matters to you) and option ratings (how well each choice performs). The result is a normalized 0–100 score per option, plus a “confidence” signal based on the gap.

You set importance from 0 to 10 for each criterion. Internally we normalize them so they add up to 1.0. If all weights are 0, we fall back to an even split so the tool always works.

For each option, we compute:
Weighted Score (1–10) = Σ (rating_i × weight_i)
Then we scale it to 0–100:
Score (0–100) = ((Weighted Score − 1) / 9) × 100

Confidence is based on how far apart the two scores are. A 1–2 point difference (out of 100) is basically a coin flip, while a 15–25 point difference is usually clear. We clamp the meter to 0–100 and show it visually.

Some decisions fail not because they’re “lower average”, but because they violate a minimum: a job that pays well but destroys your health, or a project that’s exciting but impossible within your timeline. If an option scores below your “must‑have” threshold on a criterion you marked as important, we flag it.

Frequently Asked Questions

• Is this just a fancy pros/cons list?

  It’s a structured upgrade. A pros/cons list treats every point as equal. Weighted scoring lets you express “impact matters twice as much as speed” (or vice versa), which is often the missing piece.

• What if I don’t know the ratings?

  Use your best estimate, then run a “what would change my mind?” check: move one uncertain slider up/down by 2 points and see if the recommendation flips. If it flips easily, you need more information.

• Why are Cost/Time/Risk labeled “higher = better”?

  It reduces confusion. Instead of rating “cost” as high when it’s expensive (which would lower the score), you rate cost efficiency (10 = very affordable). Same logic for time/effort and safety.

• Can I use this for business or money decisions?

  Yes — just be honest about uncertainty. For high‑stakes choices, pair this with hard numbers: runway, cash flow, unit economics, and downside planning.

• Does the tool store my inputs?

  Only if you click “Save”. Saved snapshots stay on this device (localStorage). Nothing is sent to a server.

Trade‑offs, explained: how to decide without overthinking

Trade‑offs feel hard because your brain is trying to do two jobs at once: evaluate the options and evaluate the criteria. When you’re stuck, it’s usually not because you lack intelligence — it’s because the decision is multi‑dimensional. One option is better for money, another is better for time, another is better for identity, and your mind keeps swapping which dimension is “the most important” moment to moment. The result is a loop: you argue yourself into Option A, then your brain remembers the best argument for Option B, and you start over.

A trade‑off analysis tool breaks the loop by locking the process into three steps: (1) define what matters, (2) score performance, and (3) apply guardrails. The goal is not to replace intuition — it’s to make intuition consistent. When you weigh criteria explicitly, you stop letting the loudest emotion of the moment decide for you. You also get a useful by‑product: you learn what you truly value, because the “importance weights” reveal your priorities more clearly than your thoughts do.

Step 1: Name the decision in plain language

Before scoring, name the decision like a headline: “Quit my job vs stay,” “Build feature X vs feature Y,” “Move to city A vs city B,” “Buy vs rent,” “Accept client A vs client B.” Simple naming matters because it prevents false complexity. Many “stuck” decisions are really a bundle of smaller decisions: a career move might involve identity, money, relationships, and lifestyle. Naming the decision helps you see whether you’re truly comparing two options — or comparing two futures with hidden sub‑choices.

Step 2: Choose criteria that actually move the needle

This calculator uses five common criteria that cover most decisions: Impact (value created), Cost efficiency (value per dollar), Time/effort fit (speed + workload), Safety/risk (downside protection), and Values alignment (identity fit). You can think of these as a “decision compass.” When you’re not sure what to include, start here. If you want a higher‑precision analysis, you can mentally map custom criteria into these buckets. For example, “career growth” often maps to Impact; “stress” can map to Time/effort fit and Risk; “family time” maps to Values alignment and Time/effort.

The most common mistake is using too many criteria. When everything matters, nothing matters. Five is intentionally small: it forces you to accept that you can’t optimize everything at once. Optimization is seductive, but real decisions are constrained. A decision tool should reveal constraints, not hide them behind a sea of sliders.

Step 3: Set importance weights like a grown‑up

Importance is where your values show up. If you make Impact a 10 and everything else a 2, you are saying “I’m willing to spend money, time, and take risk to get a big outcome.” That’s a valid strategy — but it’s a very different life than “I want safety, low stress, and steady progress.” The point is not to find the “right” weights. The point is to choose weights you can defend.

A helpful trick: set weights based on the cost of being wrong. If being wrong about risk would be devastating, increase Risk importance. If being wrong about cost is annoying but survivable, lower Cost importance. This keeps you from over‑valuing things that are emotionally salient but not actually consequential.

Step 4: Rate each option — and keep ratings honest

Ratings are estimates. Treat them like weather forecasts: useful, imperfect, and updated as new information arrives. To rate consistently, define anchors: 1 = terrible, 5 = average, 10 = excellent. For example, on Safety/risk, 10 might mean “downside is tiny and recoverable,” while 1 means “could cause major damage.” On Values alignment, 10 might mean “feels like me; I’d be proud of this,” while 1 means “this conflicts with who I am.”

Another common mistake is rating based on wishful thinking. If Option A only wins on Impact because you assume everything goes perfectly, that’s optimism, not analysis. A better approach is to rate based on the most likely scenario. If your best‑case scenario is important, you can use the Risk criterion to capture that uncertainty: a high‑upside but uncertain option should get a lower Safety/risk rating.

Step 5: Use the confidence meter correctly

Confidence is the gap between options. If the difference is tiny, don’t treat the recommendation as a command. Treat it as a prompt: “What information would make this clear?” When confidence is low, the tool is telling you the decision is under‑informed or closely balanced. Your next move is not to stare at it longer — it’s to reduce uncertainty.

A simple playbook: Low confidence → pick 1–2 uncertain sliders, gather one piece of data (quote, test, conversation), then re‑rate. Medium confidence → do a “stress test”: change your top weight by ±2 points and see if it flips. High confidence → act, then use your energy to execute rather than re‑decide.

Step 6: Guardrails prevent regret

Guardrails are your “must‑haves.” They stop you from choosing a high average option that violates a minimum. Examples: “I must sleep 7 hours,” “I must keep my runway above 6 months,” “I must be able to see my family weekly,” “I must avoid a legal risk,” “I must not accept a client who disrespects boundaries.” In this tool, the “must‑have threshold” flags options that score below your minimum on important dimensions. If an option fails a must‑have, it doesn’t necessarily mean “never choose it,” but it means “solve this first.”

Examples you can copy

Example 1: Career decision. Option A is a higher‑paying role with longer hours; Option B is a lower‑paying role with better alignment and lower stress. If you set Values alignment and Time/effort high, Option B often wins. If you set Impact and Cost high, Option A might win. Notice what the tool reveals: the “right” answer depends on what you value. That clarity is the value.

Example 2: Product roadmap. Option A is a feature that drives growth but is hard to ship; Option B is a smaller improvement that can launch quickly. If time/effort and risk are high importance (tight deadlines, limited team), Option B may win despite lower impact. If impact is the main goal and you have runway, Option A may win. Again, the tool converts “vibes” into a decision.

Example 3: Money decision. Option A is a purchase that improves quality of life but costs more; Option B is cheaper but less useful. If cost efficiency matters most, B may win. If impact and alignment (long‑term value, daily use) matter more, A may win. The tool prevents “guilt math” and helps you choose intentionally.

The real point: fewer decisions, better decisions

Most people don’t need more productivity. They need fewer unresolved decisions consuming mental bandwidth. Use this tool when you catch yourself ruminating. Run the analysis, save the result, and set a rule: either act on the recommendation, or gather one piece of new info and re‑run. What you want to avoid is looping with no new data. Clarity doesn’t come from more thinking — it comes from a better decision process.
