App Development Cost Calculator

Q: What about ongoing maintenance?

We estimate upkeep at 18% of build cost per year — the SaaS industry average, which covers bug fixes, dependency updates, small feature iteration, and ~0.5–1 FTE of steady-state engineering. If you plan major feature work post-launch, budget closer to 40%.

Q: Is the team dedicated or shared?

Second Talent engineers are 100% dedicated to your build for the engagement. No context switching, no "fractional" time, no hidden overhead. Designers and PMs can be fractional if your scope does not need full-time.

Model the total build cost of your app — pick the scope, platforms, features, and team country, then compare Second Talent against a US in-house team and a US agency side by side.

How the build actually unfolds

Every app moves through the same five phases. The calculator above sums the effort in each phase for your selected features and team size.

Discovery + architecture

Scoping sessions, technical spike, system design, and stack selection. Typically 5–10% of total effort. Skipping it is the single biggest reason projects blow past budget.

Design sprint

Wireframes, user flows, design system, and clickable prototypes. Runs in parallel with architecture so engineering can start on week 3 with real screens to implement.

Core build

The bulk of the timeline — auth, data model, primary user flows, and platform integrations. This is where the feature checkboxes above add weeks one by one.

Hardening + QA

Integration testing, load testing, accessibility audit, and security review. Usually 15–20% of total effort — less if QA is embedded from the start.

Launch + iterate

Soft launch, telemetry review, and the first 4–6 weeks of rapid post-launch iteration based on real usage. Often underbudgeted and absorbs 10% of the total build cost.

What actually drives app dev cost

Each of these is a lever the calculator adjusts. They compound, which is why two "similar" apps often differ 3–5× in final cost.

App scope

An MVP is 3 core flows and a database. A launch product is 10+ flows, an admin, and a paid tier. A full product adds analytics, growth loops, and cross-platform parity — 5–8× the effort of an MVP.

Platform choice

Web is cheapest. Cross-platform (React Native / Flutter) adds 25%. Dual native iOS + Android adds 75% because you are effectively building the client twice. Always model this before committing.

Real-time features

Chat, video calls, live sync, and multiplayer are the most expensive features per hour of user value. Each adds infrastructure and 4–10 weeks of engineering time.

Payments + compliance

Stripe + basic subscriptions is ~6 weeks. Add PCI scope, marketplace payouts, tax handling, or regulated industries (health / finance) and payments can become 15–25% of total build cost.

Design fidelity

A template-based UI is 1.0×. A custom design system is 1.15×. Motion-heavy, brand-forward experiences (Linear, Superhuman tier) run 1.3× because every screen is hand-tuned.

Team location

A US agency charges $150–200/hr blended. A Second Talent team in Asia runs at 25–40% of that cost, with equivalent senior engineers — and the dev agency margin disappears into your build instead of theirs.

App development cost FAQ

How accurate are these numbers?

The baselines come from Second Talent’s own 2024–2025 project data across 80+ app builds, cross-checked against public GoodFirms, Clutch, and CB Insights figures. Your actual cost will depend on scope churn, stakeholder velocity, and stack maturity — treat the output as a planning number, not a fixed quote.

What exactly is a "person-week"?

One person working for one week on the project. A 5-person team for 20 calendar weeks = 100 person-weeks. The calculator shows total effort in person-weeks and then divides by parallel team size to give the calendar timeline.

Why is a US agency so much more expensive?

US agencies typically charge $150–200 per hour blended — that covers the developer’s salary, office overhead, sales and project management layers, and a healthy agency margin. Second Talent places the engineer directly into your team with no markup beyond our flat management fee, so you pay the engineer's rate, not the agency's.

What about ongoing maintenance?

We estimate upkeep at 18% of build cost per year — the SaaS industry average, which covers bug fixes, dependency updates, small feature iteration, and ~0.5–1 FTE of steady-state engineering. If you plan major feature work post-launch, budget closer to 40%.

Is the team dedicated or shared?

Second Talent engineers are 100% dedicated to your build for the engagement. No context switching, no "fractional" time, no hidden overhead. Designers and PMs can be fractional if your scope does not need full-time.

Do you handle the entire build or just supply engineers?

Both work. The calculator models a full build team (engineers + design + PM + QA). If you already have product and design in-house, untick those boxes above or talk to us — we can supply engineering only, and the cost drops by ~30%.
