Banking App Development Cost in 2026
Neobanks, digital banking, and challenger bank apps — modern financial experiences built on banking-as-a-service infrastructure.
Digital banking apps (neobanks) have transformed how people manage money. Building one no longer requires a banking license from day one — banking-as-a-service providers like Unit, Column, and Treasury Prime provide the regulated infrastructure while you build the customer experience. The cost varies dramatically: a basic digital banking interface costs $50K-$100K, while a full-featured neobank with lending, investing, and AI financial insights can exceed $500K.

Frequently Asked Questions
How much does it cost to build a neobank app?
A neobank MVP with accounts, cards, and transfers costs $50,000-$100,000. Full-featured digital banks with lending and investing range from $250K-$700K. Using banking-as-a-service reduces cost by 60-70% compared to building banking infrastructure from scratch.
Do I need a banking license?
Not necessarily. Banking-as-a-service providers hold the licenses and handle regulatory compliance. You build the customer experience on top of their infrastructure. This is how most modern neobanks launch.
How long does it take to launch a neobank?
An MVP takes 3-4 months with BaaS integration. The biggest timeline factor is often the banking partner's onboarding and compliance review process, which can take 2-4 months in parallel with development.
Can users deposit cash?
Yes, through retail deposit networks like Green Dot or retail partners. This is typically a feature of BaaS providers and can be enabled without building your own cash deposit infrastructure.
What about FDIC insurance?
Your banking-as-a-service partner provides FDIC insurance through their partner bank. Customer deposits are typically insured up to $250,000. This is handled at the infrastructure level, not the application level.
