Repair vs. Replace Calculator
Compare repairing vs. replacing pavement on cost per year of useful life and your hold period — so the decision is about value, not just the sticker price.
At $1,200/yr vs. $1,500/yr, repair stretches each dollar further — provided the pavement is structurally repairable, not failing at the base.
Cost-per-year assumes the pavement is genuinely repairable. Once the base has failed, repeated repairs will not hold and replacement is usually the honest answer regardless of the math. Have a contractor assess the base first.
A repair almost always costs less today than a replacement, but that's the wrong comparison. What matters is the cost per year of service each option buys, and how long you'll actually own the property. This calculator makes both visible.
Enter what each option costs and how long it lasts, plus how long you plan to hold the property. You'll get the annualized cost of each, the total cost across your hold period, and a plain-English recommendation.
How this calculator works
Cost per year divides each option's price by the years of life it buys — the fairest apples-to-apples comparison.
Hold period matters. If you'll sell before a replacement would pay off, a repair can be the smarter use of capital even at a higher cost per year. The recommendation accounts for this.
Over-the-hold totals assume repairs repeat as needed to keep the pavement serviceable, while replacement is a single longer-lived event.
The base override. If the base has failed, repeated repairs won't hold — replacement is the honest answer regardless of the math. Always have the base assessed first.
- Repair cost/yr = Repair cost ÷ Repair life
- Replace cost/yr = Replacement cost ÷ Replacement life
- Lower cost/yr = better long-term value (if you hold long enough to use it)
Frequently asked questions
Should I repair or replace my asphalt?
Repair when the pavement is structurally sound and the damage is localized — it's far cheaper per year in that case. Replace when there's widespread alligator cracking, base failure, or the surface is at the end of its life, because repeated repairs on failing pavement don't hold and cost more over time.
What does 'cost per year of useful life' mean?
It's the price of an option divided by the number of years of service it buys. A $6,000 repair that lasts 5 years costs $1,200/year; a $30,000 replacement that lasts 20 years costs $1,500/year. It lets you compare a cheap short-term fix against a durable long-term one fairly.
Why does my hold period change the answer?
If you'll sell the property in 3 years, paying for a 20-year replacement means giving away most of that life to the next owner. A repair that covers your remaining ownership can be the better financial decision even if its cost per year is higher.
When is replacement the only real option?
When the base or subgrade has failed. Surface repairs and overlays rely on a sound foundation; if that's gone, patches and seal coats just delay a failure that will keep returning. Have a contractor evaluate the base before deciding.
Before you hire: Costs vary by region, project size, access, materials, labor, traffic control, disposal, site conditions, and scope. Use written proposals and contractor-specific pricing before making decisions.
