Residential Construction Cost Calculator: 2024 U.S. Median per ft²

Published reference: USD 166.00 per ft² (USD 1,786.81 per m²), NAHB: Square Foot Prices Moderate in 2024, 2024 starts.

Compare finished floor area using the reported U.S. contractor-built detached-home median. This historical contract-price reference is not an apartment or land-inclusive development budget.

Who it's for: architects, owners, and estimators who need to apply a published reference or their own dated residential construction rate using transparent arithmetic — not a market forecast — for a specific quantity and allowance set, at feasibility or schematic design.

Residential cost reference per m² or ft²

Choose a published reference, enter matching floor area, and calculate. Source facts travel with the result; you do not need to retype them.

Compare published rates and source details

Calculate from a published area rate

Choose a published reference; no rate or location is selected automatically.

Choose a reference to review its period and cost scope before calculating.

Use the selected source definition of floor area. Do not enter room, bed or seat counts.

Reference arithmetic, not a project budget. No current-price adjustment, currency conversion or extra allowance is applied. A rate's cost inclusions remain those of its source.

Have a project-specific rate or additional allowances? Use the separate manual calculation.

Calculate with your chosen rate

1. Quantity, unit and rate
2. Benchmark source and scope

Use the precision stated by the source: a year (2025), calendar quarter (2025-Q3), month (2025-08) or day (2025-08-15). Do not invent a month or copy the publication edition into this field.

State whether fees, contingency, land, external works, taxes and other costs are included. Unknown is not the same as excluded. Enter only additional, non-overlapping allowances.

3. Additional allowances
Scenario, not a forecast
Total = quantity × entered rate × (1 + entered allowances). Align currency, base date, scope, measurement basis, location, taxes, escalation and exclusions before comparing scenarios.

Method, source scope and period

1 ft² = 0.09290304 m². Divide a USD/ft² rate by this factor for USD/m². Divide m² area by the same factor before multiplying by the original rate. Only displayed values are rounded.

NIST area conversion definition. Unit conversion does not reconcile gross, net, finished or rentable area definitions.

Contractor-built detached home — national median (2024)

National median contract price per area for contractor-built single-family detached homes; excludes improved lot value. Use completely finished floor space; exclude garages, porches, carports and unfinished areas, following the survey definition. A reported median is not an individual project quote or a local range. Apartments and sale-price medians are not substituted.

NAHB: Square Foot Prices Moderate in 2024 · publication date: 2025-10-02 · period: 2024 starts.

Selected figures read 2026-09-11. That check date is not a cost observation date. Missing inclusions remain unknown, not excluded; do not automatically add land, fees, FF&E, taxes or contingency.

Two source endpoints are separate scenarios, not a statistical interval. No bed, seat or room count is converted to area.

Each button selects the stated displayed value, not a typical rate, statistical confidence interval, or recommendation. Inequality bounds are reference-only. Figures are as published on the linked page; check edition, unit, scope and what the rate includes before using one. When a base-date field is present, enter its verified date yourself; a publication year is not a benchmark base month.

How to use this calculator

1
Pick single-family or multi-family
RLB splits hard construction cost by single-family and multi-family across six cities. Enter square footage against the housing type matching your project.
2
Or use a median sale-price benchmark
NAHB gives median custom- and spec-home price per square foot by census division. Census gives median sale price and median size for a new single-family home, which is a price, not a rate.
3
Enter allowances and reconcile
Add fees, contingency, and other allowances not already inside the benchmark rate, then compare the total against a project-specific quote rather than treating it as a forecast.

The formula

Base amount = entered quantity × entered rate. Total = base amount × (1 + fees% + contingency% + other allowance%).

Worked example

Example
Illustrative arithmetic only: 1,000 square feet at a user-supplied rate of 200 per unit gives a base amount of 200,000. If the verified base rate excludes the entered 10% additional allowance, the scenario total is 220,000 in that same currency. This is not a published market benchmark.

When this estimate will be off

  • Census rows give a median sale price (417,400) and median size (2,194 sf) for a new home, not a $/sf construction rate — do not divide separate aggregate medians to create a representative construction rate.
  • NAHB price measures and RLB hard-construction measures are not interchangeable. Check the particular source population and its treatment of land, profit, and other inclusions before using any rate.
  • Benchmark rows on this page are sourced reference points, not market data for your project; no currency conversion is supplied.
  • No cost-plan, procurement, escalation, tax, finance, schedule, risk, or professional adequacy determination is made.

Frequently asked questions

Yes. Choose one of the published area references above and enter floor area in m² or ft². Its source, period and scope stay attached to the result. No unlisted model, local premium, current-price adjustment or complete project budget is inferred.

No. Room, bed and seat counts are not areas. Only the published area-reference form converts m² and ft², preserving the same area. The separate manual form needs a quantity and rate already expressed in matching units; no currency conversion is performed.

No. It applies transparent arithmetic to a user-supplied benchmark and allowances — it does not predict bids, escalation, or final cost.

Use a dated source for the same market, currency, measurement basis, scope, and project type as the residential construction project you're estimating. The benchmark table above lists sourced reference points, not market data for your project.

So nothing already included in the base rate is counted twice. Enter only allowances not already reflected in the benchmark rate itself.

Only to the extent those costs are already included in your verified base rate or explicit additional allowances. This worksheet does not separately derive or validate escalation, taxes, finance, procurement risk, or professional adequacy.
