Freelance mobile app developer rate calculator

What actually moves a mobile app developer's rate

The word "app" hides a wide range of jobs. A single-screen internal tool that reads from one API is a different job from a consumer app with offline sync, push notifications, in-app purchases, and a backend that has to hold up under real traffic. Three things decide where a build sits on that range.

• Platform choice. A native app written separately for iOS and Android is close to two projects sharing one design, so it usually costs more than a single cross-platform codebase built with a framework like React Native or Flutter. Cross-platform saves time on the first build but can cost some of it back later, when a client wants a feature that only exists as a native library on one platform.
• Backend and data. Many apps look like "just the app" to a client but actually need a server, a database, authentication and an API behind them. If you are building or maintaining that backend as well as the app itself, price it as its own line item rather than folding it into an hourly app-building rate.
• What happens after launch. An app that ships once and is never touched again is rare. Apple and Google both retire old OS versions and change their platform rules over time, so an app that worked fine at launch can fail a store review or stop working for some users a year later without a single line of new feature code. That ongoing cost belongs in the pricing conversation from the start, not as a surprise invoice six months in.

Which pricing model fits

Hourly billing fits the early stage of a project, when the client's spec is still a page of bullet points and nobody knows yet how many screens the real app needs. It also fits bug fixes and store rejections, where the scope genuinely cannot be estimated well in advance.

Milestone pricing is the usual choice once the scope is written down: a fixed fee for the design handoff, another for a working build, another for testing and store submission. Splitting a build into milestones gives the client checkpoints to approve along the way and gets you paid across the project instead of in one invoice at the end of a multi-month build.

A maintenance retainer is where a meaningful share of freelance app income ends up. Once an app is live, someone has to keep it working through OS updates, fix the bugs that only show up with real users, and resubmit when a store policy changes. Price a retainer on the expected volume of that work rather than treating it as an afterthought tacked onto the build fee.

One request worth pricing carefully rather than turning down outright: an early-stage client who offers equity or a revenue share instead of a fee. It can work as a small addition on top of a real cash rate for the build, but treat it as speculative upside, not as the income you are counting on to cover the project.

The classic mistake

The common error is quoting one number for "an app" without naming the platforms, then finding out the client meant iOS and Android both, which doubles the build without doubling the price. A second version of the same mistake is treating store review as a formality: a rejection over a missing privacy disclosure or a broken reviewer login can add a week and another submission cycle that nobody budgeted for. Name the platforms in the quote, name what happens if a submission is rejected, and put a maintenance retainer in front of the client before the app ships, not after it breaks.

How to use this calculator

Enter your target income, the weeks you actually work, and a realistic count of hours you can bill once client calls, device testing and store back-and-forth are set aside. The calculator back-solves the hourly rate that hits your goal. From there, convert it into a build price: a $90/hour target on a build that realistically takes 120 hours end to end, design handoff through submission, prices out to a $10,800 project fee for that one platform. Price a second platform, or an ongoing maintenance retainer, separately rather than assuming the first number covers everything that follows.
