Short answer
App development cost = (design + app + backend + testing + project management hours) x the hourly rate of the team, plus store fees. Hourly rates are the most sourced part: BLS, Clutch and Accelerance all publish them, and they disagree. Hours are scope-dependent and nobody neutral publishes them, so this site publishes its own and labels them.
A worked example, line by line
Our booking app example (iOS and Android from one cross-platform codebase, standard complexity, sign-up, profiles, push, booking, card payments, maps, analytics, one integration, managed backend, custom design), priced at the midpoint of Clutch's US development company band ($74.50 an hour):
| Workstream | Hours | Cost at mid rate |
|---|---|---|
| Design | 160 h | $12,000 |
| App development | 535 h | $40,000 |
| Backend and integrations | 189 h | $14,000 |
| Testing (QA) | 145 h | $11,000 |
| Project management | 103 h | $7,700 |
| Total | 1,132 h | $84,000 |
The range for the same scope is $48,000 to $151,000: 0.85 times the hours at $50 an hour up to 1.35 times the hours at $99. Open this example in the calculator.
Driver 1: platforms
Writing an app once for iPhone and once for Android roughly doubles the app-side work. Cross-platform frameworks share most of the code. Our multipliers on app-side hours: 1.0 for one platform, 1.25 for one cross-platform codebase, 1.9 for two native codebases, 0.9 for a web app. More on mobile platforms and web apps.
Driver 2: features
A small number of features carry most of the cost: real-time chat, social feeds, admin dashboards, booking engines and offline sync. Our hour allowance for each is on the cost by feature page, with dollar figures at three sourced rates.
Driver 3: backend
A managed backend (Firebase, Supabase or similar) replaces much of the server code with configuration. In our model it takes 60% of the server-side feature hours of a custom backend, with a 40-hour set-up instead of 160. Connecting to an API you already run costs least.
Driver 4: who builds it
The published rates, all read on 2 October 2026:
- Clutch, US development companies: $50 to $99 an hour (Software Development Pricing Guide, updated 21 September 2026).
- Clutch, app development companies overall: $25 to $49 an hour (App Development Pricing Guide, same date).
- Accelerance 2026: senior developers $60 to $75 in Latin America, $64 to $76 in Europe, $31 to $41 in Asia; junior developers $33 to $45, $31 to $39 and $24 to $31 respectively.
- BLS, US employees: software developers earned a median $65.38 an hour in May 2025; wages were 70.0% of private-industry employer costs in June 2026 (BLS ECEC), so the employer cost of that median is about $93.40 an hour.
Driver 5: what happens after launch
Upkeep is priced like the build, in hours. Apple raises its minimum Xcode and SDK version for App Store uploads each spring and Google Play raises its target API level each August, so an app that is not updated eventually cannot ship fixes. See maintenance cost.
Published project averages
Clutch reports an average app development project cost of $90,780.11 and an average software development project cost of $132,480.29, with usual timelines of about 11 and 13 months. These describe projects reviewed on Clutch, not a typical price for any one scope.
Questions
What is the formula for app development cost?+
Build cost is the hours each workstream needs multiplied by the hourly rate of whoever does it, summed across design, app development, backend, testing and project management. Fixed fees such as the Apple Developer Program (99 USD a year) and Google Play registration (US$25 once) are added on top, and upkeep is priced the same way as the build: hours times rate.
Why do app development quotes vary so much?+
Because both halves of the formula vary. Published hourly bands run from the low $20s (Accelerance's junior developers in Asia) to over $100 (our employer-cost figure for a 75th percentile US developer), and two firms reading the same brief can assume very different scope. Comparing quotes line by line in hours, rather than in total dollars, shows which of the two is driving the gap.
Is Clutch's $25 to $49 an hour figure the US rate?+
Not clearly. Clutch's App Development Pricing Guide gives $25 to $49 an hour as the average cost of hiring an app development company and also lists the United States at $25 to $49, while its Software Development Pricing Guide lists the United States at $50 to $99. We show both, attributed, and the calculator uses the $50 to $99 band for its US development company option.
How much of an app budget goes on testing and project management?+
In this site's model, testing is 20% of app and backend hours and project management is 10% of all other hours. These are our planning assumptions, not survey results; the methodology page explains them and the calculator applies them to every estimate.
Does using AI coding tools make apps cheaper to build?+
Accelerance's 2026 rate post attributes part of the recent fall in outsourcing rates to automation and AI-augmented developers, which is a rate effect. Whether a given team needs fewer hours for your scope is something to ask in the quote, line by line; this calculator does not apply a blanket AI discount.
