Short answer: banking app development typically costs around $45,000–$90,000 for an MVP, $90,000–$220,000 for a full-featured mobile banking app, and $220,000+ for an advanced or neobank-style platform. The biggest cost drivers are security, compliance (KYC/AML, PCI DSS, data protection), integrations with core banking and payment systems, and the number of features.

Security and compliance requirements
- KYC and AML: identity verification and anti-money-laundering checks, usually through specialist providers.
- PCI DSS: required when handling card data.
- Data protection: GDPR and UK GDPR in Europe and the UK; GLBA and state privacy laws in the US.
- Open banking: PSD2 in the EU and Open Banking standards in the UK for account access and payments.
- Security testing: penetration tests, secure code reviews and audit logging.
Compliance work often adds a significant share to the budget, so plan it from the first day rather than adding it later.
Recommended technology
- Mobile apps: Flutter for iOS and Android from one codebase, or native Swift and Kotlin for maximum platform integration.
- Back end: ASP.NET Core is a strong choice for secure, high-performance financial services; Node.js and Java are also common.
- Cloud: Microsoft Azure or AWS with encryption, key management and monitoring.
- Integrations: core banking APIs, card processors, KYC providers and payment gateways.
Ongoing costs
- Cloud hosting, monitoring and backups.
- KYC, payment and SMS provider fees.
- Security audits and penetration tests.
- Maintenance and updates, often 15–20% of the build cost per year. See our software maintenance cost guide.
How to reduce banking app development cost
- Launch an MVP with the most important features first. See our guide to building an MVP.
- Use proven providers for KYC, payments and cards instead of building them.
- Use a cross-platform framework for iOS and Android.
- Plan compliance and security early to avoid expensive rework.
