Is a Car Coating Actually Worth the Cost?
Ceramic and glass coatings can cost anywhere from a couple hundred to over a thousand dollars, but their dirt resistance can stretch out your wash intervals and cut your car wash spending. This calculator compares your wash costs before and after coating to show the payback period and total savings over the coating's lifespan, so you can see if it actually pays off.
How the calculation works
Monthly savings equals your wash cost before coating minus your wash cost after coating. The payback period is the coating cost divided by monthly savings, and the shorter it is compared to the coating's duration, the better the deal. Total savings is the accumulated savings over the duration minus the coating cost — positive means it was worth it, negative means it wasn't.
Things to consider when choosing a coating
Different coating types last different lengths of time and offer different levels of protection, so it's worth comparing a cheaper coating reapplied often against a pricier one that lasts longer based on how often you actually wash your car.
Frequently Asked Questions
Divide the coating cost by your monthly car wash savings to get the number of months needed to break even. Smaller savings mean a longer payback period.
Subtract your expected monthly wash cost after coating from your average monthly cost before coating, based on your actual wash habits.
Once the coating's effective period ends, its protection fades and your wash savings drop. Factor in reapplication cost separately.
