Short answer: Development vendors advertise the cost of building a fintech app at about $60,000 to more than $500,000, with investment and trading apps from about $125,000. These are marketing figures read on 5 November 2026, not quotes, and they disagree with one another. A real estimate is set by scope: the product type, licensed market data, broker or banking integrations, identity checks and compliance logging, security testing, platforms and maintenance drive both the build effort and the recurring bill. Estimates become comparable only when they rest on the same written scope, the same assumptions about third-party fees and the same definition of done, which is what a paid discovery phase produces.
Published price ranges for fintech apps rarely agree because they describe different products. A portfolio tracker on delayed prices, a stock trading front end connected to a broker and an e-money wallet share a category name, yet differ enormously in regulation, integration and security work.
This guide explains what drives the cost, which recurring fees third parties set, how licensing questions change the budget in Turkey and the UK, and how to make estimates comparable. Fincode publishes no price of its own here: the vendor ranges are other sellers' marketing figures, the person-day table is a labeled hypothetical, and third-party fees are quoted from official pages as of October 2026.
How much does it cost to build a fintech app?
A fintech app costs what its scope requires, and in fintech the scope is set less by screens than by data, integrations and regulation.
Every estimate combines three layers:
- Build: discovery, design, development, testing and launch, measured in person-days.
- Third-party fees: market data licenses, broker, banking or payment partners, identity verification, app stores, cloud and monitoring, most of them recurring.
- Run and maintain: fixes, operating system and API changes, security updates, support and compliance reporting.
Development vendors publish ranges for the build layer, but they describe different products and disagree with one another, sometimes on the same page.
| Vendor page (last update shown) | Fintech app overall | Investment or trading app |
|---|---|---|
| SoftTeco (updated 5 November 2026) | From around $60,000 to over $500,000 | $150,000 to $500,000+ |
| Purrweb (updated 23 July 2026) | $80,000 to $500,000+; a basic MVP $60,000 to $120,000 | $250,000 to $500,000+ |
| Cleveroad (updated 1 December 2025) | $90,000 to $300,000+ | Investment app MVP $125,000+ |
The figures conflict even within one page: Purrweb's article puts a basic fintech MVP at $60,000 to $120,000, while the estimator on the same page shows $40,000 to $70,000 for a lean fintech MVP. These are sellers' marketing figures, not quotes, a survey or Fincode prices. Disclosure: Fincode sells this kind of work, so this guide is not neutral on that point.
A quote that covers only the build is not the cost of the product. Automated trading systems follow the same logic, explained in trading bot cost; this guide focuses on customer-facing apps.
Fintech app development cost drivers
Eight drivers explain most of the difference between a small and a large fintech build.
| Driver | Lower effort | Higher effort |
|---|---|---|
| Product type | Read-only portfolio tracker | Trading, payment or custody flows |
| Market data | Delayed or end-of-day prices | Real-time depth with per-user licensing and entitlements |
| Integrations | One data provider | Broker, bank, payment and identity providers with webhooks and reconciliation |
| Identity and compliance | Email login | Identity checks, consent records, audit logs, regulatory reports |
| Security | Platform defaults | MASVS-based design, penetration tests, fraud monitoring |
| Platforms | Web or one mobile platform | iOS, Android and web on a shared backend |
| Availability | Business hours | 24/7 with redundancy and on-call |
| Markets | One language and jurisdiction | Several languages, currencies and regulators |
The drivers compound: real-time data brings entitlements and usage reporting, and payment flows bring reconciliation, audit logs and deeper security testing. Each higher-effort cell adds design, development and test work, not one feature.
Recurring costs: market data, app stores and partners
Recurring third-party fees often decide whether a product is viable, and some of them are published.
| Item | Published fee |
|---|---|
| Apple Developer Program | USD 99 per membership year |
| Google Play developer registration | USD 25, one time |
| Borsa Istanbul real-time Equity Level 1+, distributor fee (TR local) | TRY 18,000 a month plus TRY 235 per user a month, from 1 January 2026, VAT excluded |
| Borsa Istanbul delayed Level 1+ data and indices, distributor fee (TR local) | TRY 10,800 a month, from 1 January 2026, VAT excluded |
Hypothetical example: a stock app shows real-time Borsa Istanbul Level 1+ prices to 5,000 users. At the distributor fees above (valid from 1 January 2026, VAT excluded), the exchange's share alone is TRY 18,000 + 5,000 × TRY 235 = TRY 1,193,000 a month, before vendor margins and connection fees. The same app on delayed prices carries a TRY 10,800 monthly fixed fee, also VAT excluded.
Identity verification, payment processing and cloud services are usually priced per check, per transaction or per usage unit under private contracts, so ask each provider for a written quote at your expected volumes. Data licensing is covered in Borsa Istanbul API and market data and, for other exchanges, in stock market data APIs.
Licensing questions that change the budget
Whether the app needs a license, or a licensed partner, changes the architecture and timeline more than any feature, so settle it with legal counsel before estimating; this guide is not legal advice.
- Turkey: under Capital Markets Law No. 6362, receiving and transmitting orders is an investment service (Article 37) that only investment firms authorized by the Capital Markets Board (SPK) may provide (Article 39), and crypto-asset service providers need SPK permission under Article 35/B, added in 2024. Payment and electronic money services are governed by Law No. 6493 and the Central Bank of the Republic of Türkiye (TCMB, also CBRT), and banks by the Banking Regulation and Supervision Agency (BDDK).
- United Kingdom: the FCA must decide a new firm authorization within 6 months of a complete application or 12 months of an incomplete one, and for payment and e-money firms it aims to process 98% of complete applications within 3 months (2025/26 service metrics).
- Elsewhere: local securities, payments and data protection regulators apply, and an app serving several countries meets several regimes.
Many products work with a licensed partner instead, such as a broker API or a regulated payment provider. That moves cost from licensing into integration, partner fees and the partner's onboarding and certification process; broker integration is covered in broker API integration with REST and FIX.
Security work: OWASP MASVS and penetration tests
Security is a cost line of its own in fintech, planned from the first sprint rather than added before launch.
The OWASP Mobile Application Security Verification Standard (MASVS; v2.1.0 is the latest release on GitHub as of October 2026) groups controls into eight areas: storage, cryptography, authentication, network communication, platform interaction, code quality, resilience against reverse engineering and privacy. Its companion testing guide, the MASTG, describes how to verify them, and the former L1, L2 and R levels have been reworked into MAS profiles that OWASP says should be applied as a risk-based decision with business owners. For a finance app that usually means budgeting for threat modeling, secure token and key storage, server-side authorization checks, an independent penetration test before launch and retests after major changes.
Backend controls matter as much as the app: secrets in a vault, least-privilege access, audit logs and alerting. The same principles for trading systems are set out in API key security.
Team roles and phases of a fintech MVP
A fintech MVP needs more roles than its screen count suggests, because compliance, security and integration work run alongside the app.
| Role | Main contribution | When |
|---|---|---|
| Product owner | Scope, priorities, acceptance | Throughout |
| Business analyst | Flows, data and provider requirements | Discovery, build |
| UX and UI designer | Flows, disclosures, accessibility | Discovery, design |
| Mobile and web developers | Client apps | Build |
| Backend developers | APIs, integrations, ledgers, reconciliation | Build |
| QA engineer | Test plans, automation, regression | Build, launch |
| DevOps engineer | Environments, deployment, monitoring | Build, operation |
| Security specialist | Threat model, reviews, penetration test | Design, pre-launch |
| Legal and compliance adviser | Licensing, terms, data protection | Discovery, pre-launch |
The phases are discovery (scope, provider choice, licensing questions), design, incremental build, testing including partner certification and security tests, launch to a limited group, and operation. Discovery is where a credible estimate is made; skipping it moves its questions into the build, where answers cost more.
A hypothetical person-day breakdown
Effort is easier to compare than money, so the table scopes two hypothetical MVPs in person-days; the figures illustrate proportions and are not a quote.
Product A is a portfolio tracker for iOS and Android with delayed prices from one licensed vendor, manual holdings and price alerts. For a crypto version on exchange APIs, see a read-only portfolio tracker. Product B adds order entry through one broker's API, real-time prices with entitlements, identity checks through a provider and an audit trail.
| Work package | Product A | Product B |
|---|---|---|
| Discovery and specification | 8 | 15 |
| UX and UI design | 12 | 18 |
| Mobile apps (iOS and Android) | 30 | 45 |
| Backend and data integration | 20 | 35 |
| Broker integration and order management | 0 | 30 |
| Identity checks, entitlements and audit log | 4 | 20 |
| Security review and penetration test support | 5 | 12 |
| QA and test automation | 12 | 25 |
| DevOps, monitoring and launch | 6 | 10 |
| Total | 97 | 210 |
Multiply by each bidder's day rates to compare offers, then add the recurring fees above. Product B needs a little over twice the build effort of Product A, and its data and partner fees grow with every user, so its running costs can overtake the build within its first years.
Fixed price, time and materials, and comparable estimates
Fixed price suits a precisely specified first release, while time and materials suits work whose scope still depends on partner and regulatory answers.
| Model | Works well when | Risk for you |
|---|---|---|
| Fixed price | Scope, partners and acceptance criteria are settled | Change requests cost extra; a tight price can squeeze testing |
| Time and materials | Partner choice or licensing is still open | Open budget without caps and regular reporting |
| Phased milestones | Discovery, MVP and scale-up are separate decisions | Needs clear exit criteria per phase |
Estimates are comparable when they share one written scope, list the same assumptions about third-party fees and certification, state exclusions, and define done in testable terms, such as a passed penetration test or a clean reconciliation on the broker's test environment. A paid discovery phase produces that document; project and product analysis covers scope, data licensing requirements and a reasoned estimate, and a brief can be sent through the contact page.
Frequently asked questions
How much does a fintech MVP cost?
It depends on the product type, data, integrations and regulation: one vendor page advertises $60,000 to $120,000 for a basic MVP, a marketing figure read on 5 November 2026 and not a quote. In the hypothetical breakdown above, a broker-connected MVP needs a little over twice the effort of a delayed-data tracker. Ask for estimates in person-days against one written scope.
Is fintech app development cheaper in Turkey?
Day rates vary by country and team, but exchange data, app store and partner fees are set by the providers, not by where your developers sit. Compare the total cost, including recurring fees and maintenance, rather than day rates alone.
What is the largest recurring cost of a trading app?
Often licensed real-time market data and partner fees, because they scale with users. Under Borsa Istanbul's fee schedule valid from 1 January 2026 (TR local, VAT excluded), real-time Equity Level 1+ costs a distributor TRY 235 per user a month on top of a TRY 18,000 monthly fixed fee.
Do I need a license to launch a stock trading app?
It depends on the jurisdiction and on who performs the regulated activity. In Turkey, receiving and transmitting orders is an investment service reserved for SPK-authorized investment firms, which is why apps usually integrate with a licensed broker; confirm your model with legal counsel.
Why do quotes for the same app differ so much?
They usually rest on different assumptions about scope, partners, security testing and exclusions. Give every bidder the same written scope and ask them to list assumptions and exclusions.
