Cost calculator
App development cost calculator
Estimate what your app should cost to build in 2026. Five inputs, a sourced cost range, a timeline, and the year-one running cost. No email, no sales call.
Every app cost calculator produces a range, and most hide how they got it. This one shows its work. The base ranges come from our 21 app-by-app cost teardowns and the 2026 pricing datasets behind our mobile and web cost guides, the multipliers are either sourced or labeled as modeling assumptions, and the result links you to the full math for your category. Use it to set a realistic budget before you talk to any vendor, including us.
The calculator
Pick your app type, scope, platforms, and user roles, tick the add-ons that apply, and the calculator produces a build cost range, a typical timeline, and the year-one running cost most buyers forget to budget. All inputs live in the URL so you can save and share a specific estimate. No email required.
How to read the result
The range is a market band, not a quote. A fair vendor quote for the scope you selected should land inside it; a quote far below usually means scope was misread or quality will pay the difference, and a quote far above deserves a written explanation of what's driving it.
The most useful way to use the number: as a negotiating anchor and a sanity check. If you selected an MVP and the quotes you're getting are triple the top of the range, someone is scoping the full vision, not the MVP. If a quote is half the bottom of the range, ask what's missing, because the backend and API, roughly 40 to 50 percent of a typical build, is the part that vanishes from cheap quotes first.
How the math works
The calculator multiplies a category base range by platform and role factors, then applies add-on increments. Base ranges come from our published teardowns, the cross-platform factor from three corroborating 2026 datasets, and the add-ons from sourced figures: payments $10k to $20k, AI $30k to $100k, regulated data +30 percent.
The model runs three steps. First, your app type and scope select a base range: the MVP and full-scale bands come from the published teardowns and cost guides, and the competitive tier interpolates between them. Second, platform and role factors scale the range: two native apps at 1.45x reflects the corroborated 30 to 45 percent cross-platform saving123, and each extra user role adds 15 percent for the screens, logic, and testing it multiplies. Third, add-ons apply: payments with payouts add $10,000 to $20,000, an AI or recommendation engine adds $30,000 to $100,000, real-time features add 12 percent, and regulated data adds 30 percent, the midpoint of the published HIPAA range4.
The year-one running cost applies the 15 to 20 percent yearly maintenance benchmark to your build range and adds hosting at $200 to $500 a month5. Timelines use the published six to ten week MVP band3; the longer tiers are calculator assumptions.

Glossary
- MVP
- Minimum viable product: the smallest version of your app that delivers real value and lets you learn from real users. The calculator's MVP tier is where most first builds should start, because scope is the biggest cost lever you control.
- Cross-platform
- One codebase (React Native or Flutter) shipping to both the iOS App Store and Google Play. The calculator's baseline, because it costs 30 to 45 percent less than building two native apps and is the right default for most business apps.
- User roles
- The distinct kinds of user your app serves: customers, staff, admins, sellers. Each extra role seeing different data multiplies screens, logic, and testing, which is why the calculator scales cost with role count.
- Add-on
- A feature that moves cost in a way the base range doesn't capture: payments with payouts, real-time features, an AI or recommendation engine, or regulated data. Each applies a sourced increment or a disclosed multiplier.
- Year-one running cost
- What the app costs to keep alive after launch: maintenance at 15 to 20 percent of build cost per year plus hosting from roughly $200 to $500 a month at launch. An app that isn't maintained breaks with the next iOS or Android release.
Base ranges by app type
These are the ranges the calculator starts from, before platform, role, and add-on adjustments. Each row links to the teardown that establishes it, with the per-feature math and named sources.
| App type | MVP | Competitive | Full-scale | Full math |
|---|---|---|---|---|
| Business or utility app | $15k to $50k | $50k to $150k | $150k to $300k | Teardown |
| Two-sided marketplace | $30k to $70k | $70k to $130k | $130k to $350k | Teardown |
| Social network or community | $25k to $80k | $80k to $250k | $250k to $2000k | Teardown |
| Messaging or chat | $25k to $60k | $60k to $90k | $90k to $220k | Teardown |
| Video or media streaming | $40k to $70k | $70k to $180k | $180k to $300k | Teardown |
| E-commerce store or marketplace | $20k to $50k | $50k to $120k | $200k to $500k | Teardown |
| Fintech or trading | $30k to $150k | $100k to $300k | $300k to $500k | Teardown |

Modeling assumptions, stated plainly
Five constants in this calculator are modeling choices rather than published figures. Here they are, so you know exactly how much weight the estimate can bear.
The competitive tier interpolates
MVP and full-scale ranges come from published teardowns; the competitive tier sits between them. Real mid-tier builds vary with which advanced features they take on first.
Platform multipliers beyond native are estimates
The 1.45x for two native apps reflects the corroborated 30 to 45 percent cross-platform saving. The web-only (0.9x) and mobile-plus-web (1.35x) factors are calculator assumptions, since published data doesn't isolate them cleanly.
Role multipliers are directional
Extra user roles multiply screens, logic, and testing. The 1.15x and 1.3x factors express that direction; a complex admin surface can cost more than the multiplier implies.
Real-time is modeled at +12 percent
Live chat, tracking, and instant updates raise the engineering bar across the build. The flat 12 percent is a calculator assumption; deeply real-time products (a live marketplace, a trading floor) run higher.
Regulated data uses the midpoint
The +30 percent surcharge is the midpoint of the published 20 to 40 percent HIPAA range. Finance adds licensing costs the calculator deliberately excludes, because licenses are a timeline and legal question, not a software line item.
Frequently asked questions
How accurate is an app development cost calculator?
Accurate enough to set a budget band, not accurate enough to be a quote. This calculator's base ranges come from published 2026 cost data and our 21 app-specific teardowns, so the band it produces is a realistic market range for your category and scope. What no calculator can see is your specific feature list, integrations, and edge cases, which is what actually sets the price. Treat the result as the range a fair quote should land inside, then get a written scope and a fixed number. We turn a few sentences into exactly that, free, within 48 business hours.
Why does the app type change the estimate so much?
Because each category hides one hard problem that dominates its cost. A marketplace needs a trust stack (escrow, verification, split payments). A streaming app pays for content delivery forever. A fintech app needs licenses before its first user. A camera-first AR app needs a lens pipeline that adds 30 to 40 percent on its own. Two apps with the same number of screens can be an order of magnitude apart because of what's behind those screens, and the calculator's base ranges encode that category reality from our teardowns.
Is cross-platform really 30 to 45 percent cheaper than native?
Yes, and it's one of the best-corroborated numbers in app pricing: Netguru, Cleveroad, and Purrweb independently put the saving in the same band in their 2026 data. The mechanic is simple: two native apps mean designing, building, and testing nearly everything twice, in Swift for iOS and Kotlin for Android. A cross-platform build writes it once and ships to both stores. Native earns its premium only for heavy graphics or deep hardware access, which is why the calculator treats cross-platform as the baseline.
What does an MVP cost and how long does it take?
A focused mobile MVP commonly runs about $25,000 to $60,000 and ships in six to ten weeks, with the median cross-platform MVP at about $76,000 once it carries authentication, an API, and eight to twelve screens. The calculator's MVP tier reflects your category's published MVP band, adjusted for platforms, roles, and add-ons. The practical advice hiding in the numbers: build the MVP, launch it, and let real users decide what the competitive version needs. It's the single biggest saving available to you.
What running costs should I budget after launch?
Plan on 15 to 20 percent of your build cost per year for maintenance: bug fixes, operating-system updates, security patches, and small improvements. Hosting adds roughly $200 to $500 a month at launch and grows with usage, reaching $2,000 to $10,000 or more at real scale. Media-heavy and real-time apps run higher, and third-party APIs for maps, messaging, and payments commonly add $5,000 to $30,000 a year. The calculator folds the maintenance benchmark and launch-scale hosting into its year-one figure so the second number on your screen is the one most buyers forget to budget.
Why does regulated data add 30 percent?
The calculator models regulated data at a 30 percent surcharge, the midpoint of the published 20 to 40 percent range for HIPAA-compliant healthcare builds. The surcharge pays for encryption at rest and in transit, audit logging, access controls, compliant infrastructure, and the documentation that goes with all of it. The number worth remembering: retrofitting compliance after the fact costs several times more than building it in, so if your app touches health, payment, or financial data, scope it in from day one. For finance specifically, licensing can dwarf the software; our fintech teardowns cover which licenses apply.
