Worksheet
Score your product idea
Last updated: November 2026
How do I score my product idea?
Score your product idea by rating, from 1 to 5, how ready you are at each of the six stages of Cydney Mar's Concept-to-Reality Pathway, then focus on the lowest number. The total out of 30 matters less than the weak spot it reveals, because a gap in clarity, samples, suppliers, costs, production or launch is where founders most often lose time and money.

Rate your readiness at each stage
Answer honestly. Choose one rating per stage, then select Show my score. Your answers stay in your browser and are not sent or saved anywhere.
Check your margin
The Cost and Margins stage asks you to build for real profit. Enter your unit cost and planned selling price. Commas, a currency sign and spaces are fine; empty, negative or zero figures are rejected.
What scoring tools usually cover, and what they miss
What most idea scorecards measure
Most published ways to evaluate a startup or product idea look at demand: whether people want it, how big the market is, whether you can reach buyers and whether anyone else already sells it. Those are useful questions. Business guides such as SCORE cover developing a business idea in general terms, and many templates score ideas against a fixed list of metrics.
What this worksheet adds for physical products
A consumer product also has to be made. This worksheet scores the making as well as the market: whether you know which samples to build, whether your suppliers have been checked for quality, communication and reliability, whether your margin survives real costs and whether your specifications are ready for consistent manufacturing. Those stages come from Cydney Mar's 45+ years in fashion and product.

Common questions
Short answers here. Read all 43 questions on the FAQ page.
- How do I score my product idea?
- Rate how ready you are at each stage of getting a product made: clarity on what it is and who it is for, prototypes, suppliers, costs and margins, production readiness, and a launch plan. The worksheet on this site scores those six stages from 1 to 5, and the free workbook from Cydney Mar walks you through a fuller scoring exercise. More in the FAQ
- What counts as a good score for a product idea?
- There is no universal passing mark. A self-score is most useful for showing where you are weakest, not for proving an idea will sell. On this site, the lowest-rated stages are flagged as the place to focus next. Treat any score as an estimate and a planning aid, never as a guarantee of sales or success. More in the FAQ
- What's the quickest way to validate a product idea?
- Start by writing down exactly what the product is, who it is for and what problem it solves, then check your costs against a realistic selling price. The Product Clarity stage of the Concept-to-Reality Pathway comes first for this reason. Clear answers there make every later step, from samples to suppliers, cheaper to get right. More in the FAQ
- Should I score my idea before making a prototype?
- Yes. The Product Development Roadmap from Cydney Mar names jumping into sampling without clarity as one of the most common reasons product ideas stall. Scoring first shows whether you know what you are making and who it is for, so your prototype budget goes toward the right samples instead of rework. More in the FAQ
- What if my idea scores low?
- A low score usually means you have not had a map yet, not that the idea is wrong. Cydney Mar puts it plainly: it is rarely the idea, it is not knowing which step comes next. Use the low-scoring stages as your to-do list, then rescore once you have answers. More in the FAQ
- How do I calculate my product margin?
- Subtract your unit cost from your selling price, then divide by the selling price. For example, a product that costs 10 to make and sells for 25 has a gross margin of 60 percent. The margin check on the score page does this math and rejects empty, negative or zero figures. More in the FAQ
