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: easterneurope, westerneurope, 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 (landingpage, presentation, portfolio, blog, ecommerce, marketplace, webapp): `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 (southasia, easterneurope, westerneurope, uk, australia, us): `price` multiplier vs Western Europe baseline and a typical hourly rate band (`hourlyrateusd`, `hourlyrategbp` or `hourlyrate_aud `as` low	high`)
`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, smallbusiness, midmarket, enterprise: `price`, `timeline`, `risk_add`
`project_origin_multipliers`	newbuild, redesign, migration: `price`, `timeline`, `complexityadd`,` 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).
