The short answer
For a simple piston single, budget a base annual inspection in the low-to-mid four figures, plus whatever repairs it uncovers — which can easily match or exceed the inspection itself. Complex, twin, and turbine aircraft cost substantially more. Well-maintained airplanes with complete records have fewer surprises.
Base Cost Plus Repairs
The annual has two parts: the inspection labor (a base cost that scales with the aircraft's complexity) and the repairs the inspection uncovers (parts and labor to fix squawks and comply with Airworthiness Directives). On a simple single the base inspection is often low-to-mid four figures; the repairs are the wild card and can equal or exceed it. Twins, retractables, and turbines cost considerably more.
Reducing Annual Surprises
The best defense is a well-maintained airplane with complete, continuous records — which is exactly what a good pre-buy inspection confirms before you buy. Address squawks promptly rather than deferring them, follow service bulletins, and keep the airplane flying (idle airplanes develop problems). Budgeting a realistic annual figure — base plus a repair allowance — keeps the yearly inspection from being a financial shock.

Related Questions
Why do annuals vary so much in cost?
The base inspection is somewhat predictable, but the repairs it finds are not. A neglected airplane or one with deferred maintenance can produce a large annual; a well-kept one, a modest one.
Does a pre-buy reduce annual surprises?
Yes — a thorough pre-buy uncovers issues before you buy, so you're not surprised at the first annual. It's the best protection against inheriting deferred maintenance.
What's the difference between an annual and a 100-hour inspection?
An annual is required yearly for all aircraft; a 100-hour is required additionally for aircraft used commercially or for hire. The scope is similar.
