What affects the cost of subfloor repair or patch?
Size of the damaged area
A single soft spot between joists is a small patch; a rotted section spanning several joists is a much larger cut-out.
Cause of the damage
If a leak caused it, the source has to be fixed first — otherwise the new subfloor fails the same way.
Flooring above it
The finished floor has to come up and go back, and tile or glued flooring rarely survives removal.
Local labor rates
Rates vary market to market. Your quote reflects what the pro in your ZIP actually charges — not a national guess.

When should you hire a professional?
Possible if you've done this exact work before, but the margin for error is thin. One bad cut, cracked tile, or slow leak costs more to put right than the original quote — and you still end up paying a pro to finish it.
