What this estimate covers
Three paving bids can look like three prices while describing three different jobs. The cheapest one often skips base repair, uses thinner asphalt, or drops the warranty — costs you don't see until the pavement fails early. This tool reframes the comparison around value, not sticker price.
Enter each bid's price and expected life, then check off which scope items it actually includes. You'll get each bid's cost per year of useful life, a ranking, and a clear list of what's missing from each — the questions to get answered in writing before you sign.

How this calculator works
Cost per year of useful life. Price divided by the years of service each bid buys — the fairest apples-to-apples comparison, and often a different winner than the lowest price.
Scope-gap check. Toggle the items that separate a solid bid from a risky one (base repair, thickness, prep, drainage, warranty, striping) for each bid.
Ranked with gaps flagged. Bids are ranked by cost per year, with each one's missing scope items called out so you know exactly where to push back.
Frequently asked questions
How do I compare paving bids fairly?
Compare the scope, not just the bottom line. Put each bid on a cost-per-year-of-useful-life basis, then check that each includes the same base repair, asphalt thickness, surface prep, drainage, warranty, and striping. A price is only comparable when the work behind it is the same.
Why is the cheapest paving bid often the most expensive?
Because the savings usually come from things you can't see: thinner asphalt, skipped base repair, no drainage work, or no warranty. Those omissions shorten the pavement's life, so the low bid can cost more per year of service and fail years sooner than a complete one.
What does 'cost per year of useful life' mean?
It's the bid price divided by how many years of service it buys. A $42,000 job lasting 15 years costs $2,800/year; a $31,000 job lasting 8 years costs about $3,875/year. It lets you compare a durable bid against a cheap short-lived one on equal footing.
What scope items should every paving bid include?
At minimum: base and subgrade repair, a stated asphalt thickness, surface prep and crack sealing, drainage handling, a written warranty, and striping. Missing items aren't necessarily deal-breakers, but they should be priced and put in writing so you're comparing equivalent jobs.
