Appeal Savings Estimator
Most successful property-tax appeals lower the assessed value by 10% to 25%. Use the form below to project annual savings on your specific situation. Calculations run entirely in your browser.
How This Tool Works
The estimator multiplies your current assessed value by your county's effective tax rate to derive the current annual bill, then applies the reduction percentage to project a new assessed value and corresponding new bill. Annual savings is the difference; total savings projects that figure across the years you plan to remain in the home.
Choosing a Realistic Reduction Percentage
Successful informal appeals — where you present comparable sales evidence to the assessor's office without a hearing — typically yield reductions of 5% to 15%. Formal hearings before a board of equalization tend to deliver larger reductions when supported by an independent appraisal, often 15% to 25%. Reductions exceeding 30% are rare and almost always require the help of a licensed property-tax consultant or attorney. If you have not yet gathered evidence, model 10% to be conservative; if you have at least three solid comparable sales below your assessed value, 15% is a reasonable target.
Next Steps If The Numbers Look Promising
If projected savings exceed the cost of an appraisal (typically $300-$600) or the contingency fee charged by a tax-appeal firm (typically 25%-50% of first-year savings), it is usually worth pursuing the appeal. Read our step-by-step appeal guide for the procedure in your state, and use our property tax estimator to verify the rate assumptions before filing.
