Quick answer

What is a startup score calculator?

A startup score calculator is a tool that takes a one-sentence startup idea and a small set of structured inputs (target audience, monetization model, distribution channel, technical background, and the risks the founder already sees) and returns a numeric score on a 0–100 scale, usually broken into per-dimension sub-scores. The score is a structured way to compare ideas and to surface the assumptions the plan most depends on. A score calculator does not predict whether a startup will succeed — no tool can — and any calculator that promises a correlation with success is making a claim it cannot back up. The honest use of a startup score is as a decision-making input: it tells you which of the named assumptions to test first, which of the dimensions is the weakest, and which experiment is cheapest to run. Yibud's startup score calculator is the Startup MRI engine. It produces the score in under 60 seconds, free, with no signup. The score comes from a deterministic rule engine, so the same inputs always produce the same number.

Key takeaways

What a startup score is, in plain language

  • A startup score is a 0–100 number derived from a set of structured inputs — the idea, the audience, the monetization model, the distribution channel, the technical background, and the risks the founder already sees.
  • A score is a decision-making input, not a verdict. The same score can come from very different combinations of dimensions, and the per-dimension breakdown is usually more useful than the overall number.
  • Deterministic rule engines produce more trustworthy scores than LLM-generated numbers: the same inputs always produce the same output, and every score traces back to a specific fired rule.
  • A score cannot predict whether a startup will succeed. The honest use of a score is to identify the assumption most worth testing next and to prioritize the cheapest experiment that can produce evidence.
  • Free score calculators that pair the number with a structured report (risks, MVP scope, first-customer plan) are most useful to first-time founders, who would otherwise pay consultants thousands of dollars for the same analysis.

What a score is built from

Four inputs a startup score is built from

Every score is the result of four structured inputs. The clearer the inputs, the more useful the score.

  • Input 1

    The idea itself

    A one-sentence description of what the founder wants to build and who it is for. The clearer this input, the more useful the score. 'An AI tool for marketers' is too vague; 'a Slack bot that summarizes customer-call transcripts for SMB sales teams' is clear enough to score.

  • Input 2

    The target audience

    A named, reachable segment — not 'small businesses' or 'everyone'. The narrower the audience, the sharper the score. 'Independent product designers in North America who run their own studios' is the kind of input that produces a useful score.

  • Input 3

    The business model

    Subscription, one-time purchase, freemium, marketplace, ads, or 'not sure'. The business model drives the willingness-to-pay assumption, which is the single most-tested assumption in a startup score.

  • Input 4

    The distribution channel and technical background

    How the founder plans to reach the buyer (SEO, Reddit, Product Hunt, community, cold outreach, paid ads) and the founder's technical background (non-technical, beginner, intermediate, experienced). The two together determine whether the chosen distribution matches the chosen build.

Scoring factors

Six factors that influence a startup score

The six dimensions the score is built from. Each one is scored 0–100 and combined into the overall startup score.

  • Factor 1

    Market opportunity

    How large and how reachable is the target market? The score rewards large markets with strong, repeated pain and penalizes small markets with weak workarounds already in place.

  • Factor 2

    Competition

    How saturated is the market? The score rewards sharp angles into otherwise crowded markets and penalizes me-too products entering markets dominated by well-funded incumbents.

  • Factor 3

    Distribution

    Can the founder actually reach the buyer? The score rewards chosen distribution channels that match the named target audience and penalizes mismatches (paid ads to a sub-$10/month SaaS, cold outreach to a consumer segment).

  • Factor 4

    Monetization

    Does the business model produce revenue at the chosen price? The score rewards business models with evidence of willingness to pay and penalizes business models whose only evidence is the founder's belief.

  • Factor 5

    Build difficulty

    How long will the MVP take and what skills does it require? The score rewards MVPs that match the founder's skills and penalizes ambitious builds paired with non-technical founders or limited runway.

  • Factor 6

    Founder fit

    Does the founder's skills, time, and existing audience match the work? The score rewards domain expertise, an existing audience, and shipped history; it penalizes first-time founders entering unfamiliar markets with no audience.

How to use it

How founders use a startup score

Four uses, framed as decision-making inputs. The score is a starting point for action, not a verdict.

  1. Compare two or three candidate ideas on the same dimensions

    Score each candidate through the calculator. The per-dimension breakdown shows you which one is strongest on the dimensions you care about (often distribution and founder fit) and which one is weakest on the dimensions you are most worried about (often monetization or build difficulty).

  2. Identify the single critical assumption most worth testing

    Read the report's top three risks. The single critical assumption is the one whose failure would invalidate the rest of the plan. Test that assumption first, before any other.

  3. Prioritize the cheapest validation experiment

    The calculator recommends the cheapest experiment for each dimension — usually a problem interview, a landing page, or a 30-day concierge. Pick the experiment that targets the weakest dimension and run it before you write any code.

  4. Track how the score changes as you learn

    Re-run the score after each validation experiment. The score should move as you replace beliefs with evidence, and the per-dimension shifts tell you which of your experiments is producing the strongest signal.

FAQ

Frequently asked questions about startup scoring

Short answers, in the same vocabulary the Startup Validation hub uses. Longer answers live in the linked articles.

What is a good startup score?
There is no single 'good' number. A score in the 70s across most dimensions with a clear critical assumption is very different from a score in the 90s that hides a single weak dimension. The per-dimension breakdown is usually more useful than the overall number, because it tells you which assumption to test first.
Can a startup score predict success?
No. A startup score is a structured input to a decision, not a prediction. The same score can come from very different combinations of dimensions, and no published research links any particular score to any particular success rate. The honest use of a score is to identify the assumption most worth testing next — not to predict outcomes.
How is a startup score calculated?
A startup score is calculated by scoring each of several dimensions (market opportunity, competition, distribution, monetization, build difficulty, founder fit) on a 0–100 scale and then combining the per-dimension scores into an overall number. Yibud's score is produced by a deterministic rule engine, so the same inputs always produce the same output.
What factors influence a startup score?
Six factors: market opportunity, competition, distribution, monetization, build difficulty, and founder fit. Each factor is scored on a 0–100 scale. The factors are weighted and combined into the overall score, with the per-dimension breakdown usually more useful than the overall number.
Is a startup score calculator free?
Yes. A free Startup MRI score takes about five minutes and produces a structured 6-dimension report plus the overall score. No signup, no payment, no email required for the first report. The full report is yours to keep.
How long does a startup score take?
A free Startup MRI score takes about five minutes to produce. The full validation sequence — interviews, landing page, pricing experiment, 30-day concierge — takes two to six weeks. The score is the first five minutes; the sequence is the next two to six weeks.
Should I trust a high startup score?
Treat a high score as a starting point, not a verdict. A high score across all six dimensions is rare; more often the score is high on four dimensions and weak on two, and the weak dimensions are where the work is. Read the per-dimension breakdown, not just the overall number.
What is the difference between a startup score and a startup valuation?
A startup score is a 0–100 number that describes how the idea rates across a small set of named dimensions (market, competition, distribution, monetization, build, founder fit). A startup valuation is a dollar figure, derived from revenue, growth, market size, and comparable transactions. The two are different objects: a high score is not the same as a high valuation, and a low score is not the same as a low valuation. Yibud's calculator produces a score, not a valuation.

What you receive

What's in every Startup MRI score

A numeric score plus the structured report that goes with it. The number is a starting point; the report is the part you act on.

  • Overall 0–100 score

    A single number combining six per-dimension sub-scores, derived from a deterministic rule engine. The same inputs always produce the same number.

  • Per-dimension breakdown

    Six per-dimension sub-scores — market, competition, distribution, monetization, build, founder fit — each with a short plain-language interpretation.

  • Three top risks

    The risks most likely to invalidate the plan, each with a named failure mode and a recommended validation experiment.

  • MVP blueprint

    A small list of features to build first, a list to skip, and a complexity estimate.

  • First-customer plan

    The recommended acquisition channel, why it was chosen, and a 4-step plan you can run in the first 6 weeks.

Limitations

What a startup score is not

The honest list, so you do not mistake the number for something it is not.

  • It does not predict whether your startup will succeed. No tool can. The score is a list of risks and the assumption most worth testing next — not a verdict.
  • It is not a valuation. A startup score is a 0–100 number describing how the idea rates on named dimensions. A valuation is a dollar figure derived from revenue, growth, and comparable transactions.
  • It is not a market-research number. The engine has no live data feeds; the score comes from the inputs the founder typed in.
  • It is not personalised advice. The score is calibrated to the founder's inputs and a small set of named defaults — not to a founder's specific industry or geography.
