Step 1 · Market value
Likely range $2,073,021 – $2,437,239, from 10 comparable Plainsboro sales in the past 18 months (home size estimated from assessor data — range widened).
Step 2 · The Director's Ratio
The state's official measure of how far Plainsboro assessments sit below market value — republished every October, applied town-wide. A $2,238,685 home should be assessed near $1,698,714.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $151,286 above what the ratio math suggests (8.9%).
Step 4 · The tax rate — same for every Plainsboro home
$1.824 Schools · 66% $0.418 County · 15% $0.523 Town · 19%
Step 5 · The bill

A touch high — worth watching
This home's ratio sits above most of Plainsboro, but doesn't clear NJ's legal appeal line (87.26%).
