Fence Calculator
Estimate fence materials for wood privacy, chain link, split rail, farm, decorative panel, or custom fence projects by length, posts, panels, gates, concrete, waste, and cost.
Fence Project Estimate
Activity Accounts planning estimate. This is not a contract, certified estimate, or professional appraisal.
Fence project and quote calculator
Estimate fence materials and rough project cost, review a contractor proposal, or build a detailed fence bid with editable local costs.

Fence layout and materials
Total run length includes gate openings. Gate footage is deducted before panels or sections are rounded up. Post spacing is the maximum planned center-to-center distance.

Contractor quote and modeled allowances
Quote scope checklist
Check only items the proposal clearly confirms. This checklist organizes scope and does not assign prices.
Quote check results
A difference between the modeled estimate and contractor quote may reflect material grade, terrain, rock, demolition, disposal, gate construction, post-setting method, access, local labor, permits, insurance, warranty, scheduling, or site conditions not represented here.
This tool helps organize and compare quote information. It cannot verify property boundaries, inspect underground conditions, judge workmanship, or determine whether a contractor's price is fair.
Questions to ask about the quote
- Is the exact fence type and material grade stated?
- Is total linear footage stated?
- Are fence and gate heights stated?
- Is post spacing stated?
- Is the post-setting method described?
- Are gate sizes and hardware specified?
- Is existing-fence removal included?
- Are disposal and cleanup included?
- Are terrain or rock charges explained?
- Are property-line responsibilities explained?
- Are permits or HOA approvals addressed?
- Is a warranty stated?
- Are change-order conditions explained?
1. Project and materials
The shared fence inputs above calculate panels or sections, posts, gates, concrete, and their current unit-price totals.
Gate openings are deducted from panel or section footage. Gate assemblies remain priced separately through the shared cost-per-gate input.
Materials subtotal: $0.00
2. Crew and labor
Loaded hourly cost means the business's total hourly employment cost—not only the employee's wage. It may include payroll taxes, workers' compensation, insurance, benefits, paid leave, and other employer costs.
Labor subtotal: $0.00 · Crew-hours: 0.00
3. Equipment
Equipment subtotal: $0.00
4. Other direct job costs
Other direct costs subtotal: $0.00
5. Overhead, contingency, and profit
A target margin is not the same as a markup. The calculator divides cost by one minus the target margin to produce the intended gross-margin percentage.

Cost estimator
Edit the panel, post, gate, and concrete bag prices in the calculator above. The estimate separates each material category first, then applies the waste percentage to the material total so you can compare base cost and extra allowance.
Waste allowance
Default 10%. Fencing usually needs less waste than mulch or gravel, but extra material helps cover cuts, corners, damaged boards, layout mistakes, and uneven property lines. For simple straight runs, 5% may be enough; for privacy fences with corners or slopes, 10% is safer.
Common post spacing assumptions
| Fence type | Common post spacing |
|---|---|
| Wood privacy fence | 6 to 8 ft |
| Chain link fence | 6 to 10 ft |
| Split rail fence | 8 to 10 ft |
| Farm fence | 8 to 12+ ft |
| Decorative panel fence | Based on panel width |
Plain-English guide
Start with the total fence length in feet. Choose straight run for a line of fence with end posts, or closed perimeter for a loop around a yard or enclosure. Gates are subtracted from the panel length because they replace part of the fence run, but gate costs are still counted separately. Panel counts are rounded up because partial sections usually still require a full panel or section.
Fence calculator FAQ
How far apart should fence posts be?
Many wood privacy fences use posts every 6 to 8 feet. Chain link, split rail, farm, and decorative panel fences vary by product, soil, wind, terrain, and local requirements.
How many posts do I need for 100 feet of fence?
For a straight 100 ft run with 8 ft spacing, use ceiling(100 / 8) + 1, or 14 posts. For a closed perimeter, use ceiling(100 / 8), or 13 posts.
How much concrete do I need per fence post?
Small posts may use about one bag per post, while larger posts, deeper holes, loose soil, or gate posts may need more. This calculator leaves bags per post editable.
Should gates count in fence length?
Measure the full fence layout including gate openings, then enter the number and width of gates. The calculator subtracts gate width from panel length while still counting gate cost.
How much extra fence material should I buy?
A 5% to 10% extra allowance is common. Corners, slopes, cuts, damaged boards, and layout changes can push the safer estimate toward 10%.
