FEN-CAP-001v1.0.0Project inputs
Enter your measurements. Switching units converts the same project, including coverage and unit rates. Package yields keep the unit printed beside each field.
Refine measurements and rates at any time. Your current values are included in the material-list PDF.
Planning estimate, not engineering advice. Confirm site measurements and product specifications. Calculation limits.
Caps equal the posts you will set, rounded up after a spare allowance.
- Use the post count from the fence, vinyl or aluminum takeoff, including gate posts.
- Pyramid, flat and solar caps are a SKU, not this count.
- Concrete and rails stay companion lines.
Add your project costs
Enter supplier prices and any labour, equipment or delivery costs. Pick a currency — badges, inputs, and totals follow.
Costs use the post, panel, fabric, stain or cap rate you type. Construclytic does not fetch fence-yard prices. Gates and slope racks stay extras. For GCC projects, select QAR, AED, SAR, KWD, OMR or BHD and enter local supplier rates.

Caps equal the posts you will set, rounded up after a spare allowance.
FEN-CAP-001 is the named cap takeoff when you already know how many posts you will set. Caps = posts × (1 + spare), rounded up. Pyramid, flat and solar caps are a SKU, not this number. Concrete bags stay the post-hole tool.
Worked example. Example: 14 posts with 5% spare rounds to 15 caps.

This separate example uses the calculator's starting values in imperial units. It stays unchanged when you edit the tool above. Example rates, yields and dimensions are assumptions, not recommendations for your project.
| Input | Example value |
|---|---|
| Posts to cap | 14 count |
| Spare caps | 5 % |
Example result: Caps to order — 15 caps.
caps = ceil(posts × (1 + spare))
Use the labelled units above when reproducing this example. To work in metric, switch the calculator to Metric; applicable measurements are converted, while product-specific units remain labelled.
- 1. Use the post count from the fence, vinyl or aluminum takeoff, including gate posts.
- 2. Pyramid, flat and solar caps are a SKU, not this count.
- 3. Concrete and rails stay companion lines.
Field notes that change the number
- Use the post count from the fence, vinyl or aluminum takeoff, including gate posts.
- End posts sometimes want a different cap — count them here and pick the SKU at the yard.
- Vinyl may show a courtesy cap equal to posts. This page is the named cap line.
Common mistakes
- Forgetting gate posts.
- Folding caps into the panel SKU.
- Calling this a post-size or frost-depth design.

Questions
Questions about fence post caps
Do end posts need a different cap?
Sometimes. Count them here and pick the SKU at the yard.
Are post caps in the vinyl calculator?
Vinyl shows a cap equal to posts as a courtesy. This page is the named cap takeoff when you already know the post count.
What is the formula ID?
This fence post cap calculator publishes formula FEN-CAP-001, version 1.0.0. The ID stays on the result and on the estimate line.
