I went bottom-up, starting with households and trying to work out how often people repaint and how much paint a room takes.
Break down the US paint market into residential and non-residential segments, then estimate demand using a bottom-up approach based on number of households and commercial spaces, frequency of repainting, and average paint consumption per project. Alternatively, use a top-down approach leveraging known industry data or proxies like GDP contribution. Clearly state assumptions and validate with a sanity check.
Pro tip: Show that you understand the difference between volume (gallons) and value (revenue) and that you can segment the market by end-use (DIY vs. professional) and product type (interior vs. exterior, water-based vs. solvent-based). This demonstrates business acumen and attention to detail.
Clarify what 'paint market' includes: architectural coatings (residential/commercial), industrial coatings, and special-purpose paints. Specify whether you're estimating volume (gallons) or value (revenue).
Divide the market into key segments: residential (homeowners, renters, new construction) and non-residential (offices, retail, industrial, institutional). Consider DIY vs. professional contractors.
For each segment, estimate the number of units (e.g., households, commercial buildings), the frequency of repainting (e.g., every 5-7 years), and the average paint required per project (e.g., gallons per square foot).
Multiply the number of units by frequency and average paint consumption to get total volume. Convert to revenue using average price per gallon. Sum across segments.
Validate your estimate against known benchmarks (e.g., US Census data, industry reports) and adjust assumptions if necessary. Discuss potential sources of error and how you would improve the estimate.
