Cost to build an app like Robinhood
A Robinhood-like app is the most regulated shape in this library. Brokerage operations require FINRA membership or a clearing partner, and every screen showing a price is subject to market data licensing. Technically, the hard problem is real-time quote distribution — pushing live prices to hundreds of thousands of concurrent clients without falling behind the market.
What you are actually building
An app like Robinhood is three or four screens people recognise sitting on a great deal of engineering they never see. These are the screens that define the shape — and the part of each one that costs real money.
Balances are a ledger
Double-entry, not a balance column. Getting this wrong is unrecoverable, so it gets built once, slowly, by someone senior.
Moving money
Transfers, cards, rails, limits, reversals and reconciliation — each one a partner integration with a sandbox and a certification.
Identity and fraud
KYC, document capture, sanctions screening, device fingerprinting and step-up auth. Compliance here is a feature list, not a checkbox.

What makes a Robinhood-like app expensive
Three things dominate this shape of product. Everything else is comparatively ordinary app development.
Real-time market data
Licensed feeds, fan-out to every connected client, and a client that renders continuously without draining the battery.
Order handling
Order types, validation, routing to a clearing partner, fills, partial fills and cancellations — with strict idempotency because a duplicate order is a real loss.
Regulatory surface
Suitability, disclosures, statements, tax documents and audit trails, all of which have prescribed formats and deadlines.

How long, and who builds it
The $1,183,000–$1,884,000 figure assumes this schedule and this team. Both scale with the answers in the calculator above — and neither is a quote.
Delivery timeline — 8–11 months
- Discovery & product definition4–5 wks
- UI/UX design6–8 wks
- Development (app + backend)18–25 wks
- Integrations & infrastructure5–7 wks
- QA & security testing5–7 wks
- Store submission & launch2–3 wks
The team — 10 people

- Security engineer1×
- Data / ML engineer1×
The phases add to more than the total on purpose: design starts before discovery finishes and QA runs alongside development rather than after it. 10 people is about 9.5 full-time equivalents — a smaller team takes proportionally longer, and a much larger one does not go proportionally faster. The two roles most often missing from a first plan are DevOps and QA, which together are 17% of this build.
Technology considerations
A stack that would serve this product shape well. A recommendation for what you could build — not a claim about what Robinhood runs.
| Layer | Suggestion |
|---|---|
| Mobile | Native iOS and Android with a high-frequency chart and quote renderer |
| Backend | Java or Go services; order handling isolated with strict idempotency |
| Database | PostgreSQL for accounts and positions, a time-series store for market data |
| Cache | Redis for quote fan-out |
| Search | OpenSearch for symbol and company lookup |
| Real-time | WebSocket fan-out for live quotes — the hardest scaling problem in the build |
| Cloud | AWS |
| CDN | CloudFront |
| Monitoring | Datadog with order-latency and market-data-lag dashboards |
| ML serving | A managed inference endpoint (SageMaker, Vertex AI) with an offline evaluation pipeline |
Top cost drivers
- 1
Enterprise backend architecture15% of the build
Justified by a contractual uptime commitment, a regulated workload, or a user base large enough that an hour of downtime is a material financial event.
- 2
Medium scale traffic and usage15% of the build
Caching, queues and real monitoring become mandatory. That is real engineering: caching layer (redis or equivalent) in front of hot reads; background job queue for anything slower than a request; read replicas and query-level database tuning. Lower your year-one traffic assumptions and this shrinks immediately.
- 3
PCI DSS, SOC 2 Type II, KYC / AML compliance work9% of the build
Engineering and evidence work to make an audit survivable. Certification fees, legal review and auditor time are separate costs that this estimate excludes.
- 4
6 third-party integrations4% of the build
Every external service is code you write, failure modes you handle and an API that will change without asking you. The ones you can defer are the cheapest scope cuts available.
- 5
iOS + Android, native3% of the build
Two separate native codebases means the client is built twice. Moving to React Native or Flutter would cut roughly a third of your mobile hours, at the cost of native modules wherever you touch device hardware.
- 6
Premium design2% of the build
Roughly 20 screens with research, motion and accessibility work. Dropping to Custom would save a meaningful share of this without making the product look unfinished.
Infrastructure and maintenance
Neither of these is part of the build figure, and neither of them stops.
Cloud infrastructure
$3K – $18K/month
- Baseline environment$120–$420
- Application compute$2,700–$9,600
- Database$7–$27
- Object storage$105–$130
- CDN & bandwidth$2–$5
- Transaction processing infrastructure$5–$20
Annual maintenance
$177K – $471K/year
15–25% of build cost per year: bug fixes, iOS and Android version updates, SDK and dependency upgrades, security patching and small improvements. Cloud costs are the separate figure alongside.
Building an app like Robinhood — common questions
How much does it cost to build an app like Robinhood?
Using this site's default profile — 11 features, ios + android, native, a enterprise backend and medium scale traffic — the estimate is $1,183,000 to $1,884,000 for a US team, or roughly 7,822 engineering hours at a blended $168–$215 per hour. That figure covers design, both apps, backend, infrastructure, integrations, security, QA, DevOps and project management. It excludes cloud hosting, vendor fees, marketing and legal. Change any answer in the calculator on this page and the number moves with it.
How long does it take to build an app like Robinhood?
About 8–11 months with the team this estimate assumes — 10 people, roughly 9.5 full-time equivalents. Discovery and design run first and partly in parallel, development takes about half the calendar, and QA overlaps the back half rather than following it. A smaller team takes proportionally longer; a much larger one does not go proportionally faster, which is why compressing this schedule costs more than it saves below a certain point.
What team do you need to build an app like Robinhood?
1× product manager, 1× business analyst, 1× ui/ux designer, 1× mobile developer, 2× backend developer, 1× devops / sre (part-time), 1× qa engineer, 1× security engineer, 1× data / ml engineer. That is what 7,822 hours of work distributed across 10 disciplines actually requires. The roles people most often leave out of their own plan are DevOps and QA, which together are about 17% of this build.
What does an app like Robinhood cost to run each month?
Cloud infrastructure is estimated at $3,478 to $18,052 per month at the scale this profile assumes, driven mainly by compute and database. Third-party services add $600 to $7,500. Separately, budget $177,000 to $471,000 a year for maintenance — bug fixes, OS and SDK updates and security patching. None of these are part of the build figure.
Can a startup build a brokerage app?
Through a partner, yes. Apex Clearing, DriveWealth and similar providers supply the brokerage rails so you build the experience. Doing it independently means becoming a broker-dealer, which is a multi-year regulatory project rather than a software one.
What does market data cost?
Real-time US equity data is licensed per user per month, and the fees scale with your user base. It is a material operating cost that belongs in your business model, not in the build estimate.
