Website & App Project Cost Benchmarks 2026

Website & app project cost benchmarks - calibrated on 600+ project quotes and public rate benchmarks. CC-BY 4.0. Source and methodology: https://projectcostestimator.com

This is the dataset behind Project Cost Estimator, an independent website cost estimator. The canonical machine-readable source is the live endpoint https://projectcostestimator.com/api/cost-data (no auth, CORS open). The files here are a published snapshot of that endpoint plus two CSV views derived from it.

Files

File	Contents
cost-data.json	Raw snapshot of the live API response (Schema.org Dataset JSON-LD wrapper, all data under the data key)
hourly_rates.csv	Tidy table of web developer hourly rates: one row per platform x region x tier
cost_benchmarks_flat.csv	Mechanical flatten of the whole data object: category, item, attribute, value

What is in the data

All monetary values are USD unless the key says otherwise (hourly_rate_gbp, hourly_rate_aud).

hourly_rates.csv columns

Column	Meaning
platform	One of 12: wordpress, shopify, shopify_plus, woocommerce, magento2, magento1, prestashop, bigcommerce, wix, squarespace, webflow, custom
region	One of 6: eastern_europe, western_europe, uk, us, australia, south_asia
tier	freelancer or agency
low_usd_per_hour	Low end of the observed rate band
median_usd_per_hour	Median observed rate
high_usd_per_hour	High end of the observed rate band

Rate sources: Clutch (Apr 2026), Talmatic Global Snapshot, Arc.dev, Upwork medians, TechReviewer, plus other public rate benchmarks. See https://projectcostestimator.com/rate-database for the sourced, human-readable version.

cost-data.json fields (under data)

Key	Meaning
base_project_types	Per project type (landing_page, presentation, portfolio, blog, ecommerce, marketplace, web_app): base_price_usd, base_weeks, base_complexity (0-100 score), default_platform
platform_multipliers	Per platform (wordpress, shopify, woocommerce, magento, custom): price and timeline multipliers vs the WordPress baseline, complexity_modifier, hosting_monthly_usd, saas_fee_usd
geographic_multipliers	Per market (south_asia, eastern_europe, western_europe, uk, australia, us): price multiplier vs Western Europe baseline and a typical hourly rate band (hourly_rate_usd, hourly_rate_gbp or hourly_rate_aud as `low
pricing_tier_multipliers	freelancer vs agency: global price multiplier, hourly_reference_usd, service_markup
urgency_multipliers	relaxed, normal, tight, rush: price, timeline, risk_add (percentage points added to the risk score)
client_type_multipliers	startup, small_business, mid_market, enterprise: price, timeline, risk_add
project_origin_multipliers	new_build, redesign, migration: price, timeline, complexity_add, risk_add
safety_buffer	Contingency fractions: default, by_complexity (low, medium, high), by_origin
compound_multiplier_cap	Cap applied to the product of all multipliers (8)
median_project_cost_usd	Median delivered project cost, freelancer vs agency, for 12 project or platform archetypes
platform_subscription_fees_monthly_usd	Published monthly plan fees for Shopify, Wix, Squarespace, Webflow
methodology	calibration_sample (600+ quotes), markets_covered (6), accuracy_band, the 9 engine names
hourly_rate_database	The nested source of hourly_rates.csv: rates[platform][region][tier] = {low, median, high} in USD per hour

cost_benchmarks_flat.csv columns

Mechanical flatten of every leaf value in data. category is the top-level key, item the second-level key, attribute the remaining dotted path. Scalar lists are joined with | (for example a rate band 25|50 means low 25, high 50).

Methodology in one paragraph

Base prices per project type are calibrated against 600+ real project quotes across 6 geographic markets, then adjusted by platform, geography, provider tier, urgency, client type and project origin multipliers, with a compound multiplier cap and a complexity-based safety buffer. Stated accuracy band: +/-18%. Full write-up: https://projectcostestimator.com/methodology

Freshness

The live endpoint is the source of truth; this snapshot is refreshed when the upstream data changes (dateModified inside cost-data.json tells you the upstream revision date).
