Handrail priced per foot, built from your costs.
Rail jobs get quoted per linear foot, but they are built from posts, material, shop hours, field hours and finish. Enter your own unit costs and labor rates. The calculator shows what each foot really costs and what it should sell for.

Every default is an example, not a market rate. Use your own costs, and confirm rail height, post spacing and load requirements from the drawings and governing code.
Linear feet hide the real cost drivers.
Two jobs with the same footage can price very differently. Count these before you trust a per-foot number.
Posts and base plates
Post count follows spacing and run breaks, not just length. Short runs carry more posts per foot.
Returns, ends and transitions
Every run start, end and stair-to-landing transition adds shop time.
Mounting condition
Core-drilled, side-mounted, embedded or bolted plates each change field hours.
Finish
Hot-dip galvanizing, powder coat and field paint carry different costs and lead times.
Infill
Pickets, cable, mesh or glass change material and labor far more than the top rail does.
Access
Lifts, stairs-only access and occupied buildings slow installation.
Same percentage, different price.
A 20% markup on cost is not a 20% margin on price. Know which one your bid sheet uses.
| On $10,000 cost | Price | Profit | Margin | Markup |
|---|---|---|---|---|
| 20% markup | $12,000 | $2,000 | 16.7% | 20% |
| 20% margin | $12,500 | $2,500 | 20% | 25% |
Calculators check one number. Bids need every quantity.
RenderDraw proposes miscellaneous metals quantities, including rail runs, posts and stair stringers, from the drawings with source references, and your estimator approves them before pricing.
- Source on every row. Each proposed quantity keeps the sheet and location it came from.
- Estimator approval before pricing. Your estimator accepts, corrects or rejects proposals; nothing is priced until it is approved.
- Addenda through the same review. Changed sheets go back through takeoff and estimator review.
- Your assemblies, your rates. Approved rows hand off to your assemblies, labor units and pricing inputs.
Handrail cost calculator, answered.
How much does handrail cost per linear foot?
It depends on material, infill, finish, mounting and access, so build it from your own costs: material and finish per foot, posts and plates per each, shop and field hours, then overhead and profit. The calculator does that roll-up.
How do I count handrail posts?
Divide each run's length by the post spacing and round up, then add one post to close the run. Use the spacing on the drawings; short runs carry more posts per foot.
What is the difference between markup and margin?
Markup is profit as a percentage of cost; margin is profit as a percentage of price. 25% markup equals 20% margin. Price = cost × (1 + markup), or cost ÷ (1 − margin).
Should shop and field labor be priced separately?
Yes. Shop rates and field rates usually differ, and field hours depend heavily on mounting and access conditions.
Does this calculator check code compliance?
No. Rail height, opening limits, post spacing and loads come from the drawings and the governing code.

A focused, no-obligation evaluation on your own drawings. Your sample files remain private while we assess the request.
- Upload one representative plan set (a legible PDF set is the most reliable starting point), plus an addendum if you have one.
- RenderDraw reviews the set and the scope you want tested.
- We follow up with what was extracted, what was flagged for review, and the most useful next step.
