## What homes at different prices pay in Plainfield City

Assessments in Plainfield City averaged 24.85% of true value, which is why its general rate (8.926) is higher than its effective rate (2.460). A home is not taxed at the general rate on its full market value. The table turns each market value into an assessed value with that 24.85% average ratio ([Amended Table of Equalized Valuations 2025](https://www.nj.gov/treasury/taxation/pdf/lptval/2024/2025TEV.pdf)), then applies the general rate.

| Market value | Est. assessed value | Est. yearly tax | Per month |
| --- | --- | --- | --- |
| $300,000 | $74,550 | **$6,654** | $555 |
| $450,000 | $111,825 | **$9,982** | $832 |
| $600,000 | $149,100 | **$13,309** | $1,109 |
| $800,000 | $198,800 | **$17,745** | $1,479 |
| $1,000,000 | $248,500 | **$22,181** | $1,848 |

Individual assessments vary around the town average, so a home's real assessed value can be higher or lower than the estimate here. The figure on your own bill or assessment notice is the one that counts.
