What does a contingency fee really cost?
Compare hypothetical fees across separate appeal years. Results depend on your evidence, local rules and the provider’s contract; savings do not automatically repeat.
Illustrative fee difference: $1,005 over 5 years.
Assumes a new successful appeal with identical savings and fees in every selected year, and a new $49 Audit purchase each year. This is not a prediction or a claim of equivalent results. Audit availability depends on evidence. The $29 national DIY kit is a separate product; government fees and your time are excluded.
The fine print the percentage hides
Assessments and outcomes can change. Do not assume one appeal locks in a lower bill or that a renewed service charges for the same historic reduction. Check each contract and tax year.
The calculator uses illustrative percentages, not current provider quotes. Ownwell’s pricing page describes fees on savings in the year appealed, with local pricing. Sources checked September 20, 2026.
Our $29 national DIY kit gives you guidance and worksheets; you gather evidence. The $49 Audit depends on available county and address records and provides the filing or valuation output supported by them. You file yourself. Neither product guarantees the same evidence, representation or outcome as a managed service. Government fees and preparation time are separate.
