Easement & right-of-way value impact calculator
How much does an easement reduce land value? Enter your parcel size, market value, and the proposed corridor, and this tool estimates the impact the way an appraiser would: the value lost inside the corridor plus the damage to the rest of the parcel. No account, no cost, and every assumption is shown.
Rural acreage is often 70–100% land. A small lot with a large house is often 20–35%.
Tailors the assumptions, the disclaimers, and — where state law actually bears on value — the range itself.
$4,556 – $9,762
Most likely $7,159 — about 1.6% of the property value (range 1.0% to 2.2%).
| Component | Low | Likely | High |
|---|---|---|---|
| Value lost inside the corridor$13,017 of land, 8.3% of the parcel | $4,556 | $7,159 | $9,762 |
| Damage to the remainderLand outside the corridor, affected by where it runs | $0 | $0 | $0 |
| Total estimated impact | $4,556 | $7,159 | $9,762 |
Land value used: $315,000 per acre.
- 1Land is valued at $315,000 per acre (35% of the $450,000 property value spread across 0.500 acres).
- 2The easement covers 1,800 sq ft (0.041 acres), or 8.3% of the parcel, worth $13,017 unencumbered.
- 3A underground utility line (water, sewer, electric, cable) typically costs 35%–75% of the land value inside the corridor, because the holder controls that strip but you keep title to it.
- 4Damage to the remainder starts at 0.0%–2.0% of the $144,483 of land outside the corridor.
- 5"Runs along a boundary or existing edge" reduces the remainder damage, because a corridor tucked along an edge leaves the usable interior intact.

This calculator produces a preliminary planning range, not an appraisal. Easement damages depend on local market evidence, the exact recorded language, and the improvements involved. Have a licensed appraiser, surveyor, or real estate attorney review anything you rely on for a purchase, a condemnation claim, or a construction decision.

What courts have actually awarded
Real decisions in which a court put a dollar figure on an easement. In the cases below that report both numbers, damage to the rest of the property accounted for between 26% and 98% of the total, with a middle figure near 72% — which is why the strip alone is rarely the whole story.
These awards are historical and reflect land values, uses and law at the time each case was decided. They show how courts reason about easement value; they are not a prediction of what your property is worth.
Buried water, sewer, electric, and communication lines are the most common and usually the cheapest kind of encumbrance. You keep lawn, garden, and often parking use; you lose the right to build structures or plant deep-rooted trees over the line, and the holder can excavate to repair it.
How this calculator works
Nothing here is a black box. Every figure comes from the inputs above and the five rules below, so you can argue with the assumptions instead of guessing at them.
Before-and-after (larger parcel) framework
Appraisers value a partial acquisition by appraising the whole property before the easement, then appraising it again subject to the easement. The difference is the compensable impact. This calculator reproduces that structure with two components you can inspect separately: the value lost inside the corridor, and the damage to the remainder of the parcel.
Corridor value uses a percentage of fee, not the full fee
An easement is not a sale. You keep title, you keep the property tax bill, and you usually keep some use of the strip. Market practice is to pay a percentage of the underlying land value for the encumbered area — commonly a third for a buried utility line that leaves the surface usable, and near the full fee where the holder gets exclusive, no-build control. The model applies a per-type band and then shifts it up or down based on the restriction level you choose.
Damage to the remainder is where the real money hides
A ten-foot utility strip along a back fence rarely changes what a buyer will pay. The same ten feet through the only spot the house fits can cost far more than the strip itself. The model adds remainder damage when the corridor crosses the buildable area, affects the only legal access, or splits the parcel, and reduces it when the corridor hugs an existing edge.
Land value is separated from improvements
Easement damage attaches primarily to land and to what you can build on it, so the model works from the land component of value. The land share defaults to a typical suburban split; raise it for rural acreage where land is most of the value, and lower it for a small lot with an expensive house on it.
Why the range is wide
Published easement settlements for similar corridors routinely vary by a factor of two or more between markets. A wide range is honest. Treat the low end as the outcome where the corridor is a nuisance only, the high end as the outcome where it genuinely changes what the property can become, and the midpoint as the starting point for a conversation with an appraiser.
