Entry & exterior door replacement cost
Price a front, back or side entry door from your own quoted numbers — door, labor, add-ons and a contingency buffer — then sanity-check it against the labeled installed bands.
An entry door at $1,200.00 plus labor and add-ons is about $1,760.00 (labeled bands: steel $500.00–$1,500.00, fiberglass $800.00–$2,500.00 installed). Enter your own prices — a planning estimate, not a bid.
Calculator inputs
An entry door is more than a slab: the price you pay bundles the door, the labor to pull the old one and hang and seal the new one, and the add-ons that quietly move the total — sidelights or a transom, a lockset and deadbolt, weatherstripping and threshold, exterior trim and haul-away of the old door. This estimator takes the numbers from your quote and returns a single planning total so you can compare bids on equal footing.
It covers any non-garage exterior or interior swinging door — front, back, side, patio-adjacent or an interior passage door. Garage doors and openers are a different trade and are not sized here. For a slider or a French pair, use the dedicated patio / sliding and French door tools, whose bands differ.
Formula
The cost identity is the fleet-standard estimate, with an explicit contingency multiplier:
total = (count × price/door + labor + add-ons − discount) × (1 + contingency%)
Every dollar figure is a value you enter from a real quote or bill; nothing is hard-coded. The contingency is applied to the whole subtotal because surprises — a rotted jamb, an out-of-square opening, an extra trip — scale with the size of the job, not just the door.
Worked example
One fiberglass entry door at $1,200, install labor $400, no add-ons, no discount, at a 10% contingency:
(1 × 1,200 + 400 + 0 − 0) × 1.10 = 1,600 × 1.10 = $1,760
Add a $250 lockset-and-deadbolt package and two $600 sidelights and the same formula returns (1,200 + 400 + 1,450) × 1.10 = $3,355 — a reminder that on entry doors the add-ons often outweigh the labor.
What moves an entry-door price (and common mistakes)
Slab vs pre-hung. A slab (door only) is cheaper but only works when the existing jamb is sound and square; a pre-hung brings a new jamb, weatherstrip and threshold and hangs plumb far more reliably. See the slab vs pre-hung reference before you price.
Measure the rough opening first. If the door size changes, the framed opening may need work — that is carpentry, not door cost. The door rough-opening calculator gives the pre-hung allowance.
- Under-counting add-ons. Hardware, sidelights, storm door, painting/staining and disposal are the line items that blow past a headline door price.
- Ignoring access. A tight interior turn or a second-floor entry adds labor.
- Pre-1978 homes. Disturbing old paint triggers EPA RRP lead-safe practices — budget it (reference).
Reference table
Installed price ranges are labeled planning bands (material plus labor) — a sanity check on your quote, never a substitute for it. You enter the real price; these only tell you whether a number looks unusually low or high.
| Door type | Typical installed / door | Notes |
|---|---|---|
| Entry — steel | $500.00–$1,500.00 | Value / security default |
| Entry — fiberglass | $800.00–$2,500.00 | Dent- and weather-resistant |
| Patio / sliding glass | $1,000.00–$3,500.00 | Horizontal glider |
| French | $1,500.00–$4,500.00 | Hinged single or double |
| Storm | $150.00–$600.00 | Secondary outer door |
Bands are LABELED typicals — confirm with itemized quotes from licensed, insured installers; they vary by size, glass package, hardware, sidelights, disposal and local labor.
