TL;DR — cost at a glance
A neobank is cheaper to build than most founders expect — because the expensive part (the bank) is rented, not built. The essentials:
- MVP cost: $250,000–$500,000 on a banking-as-a-service (BaaS) platform — apps, onboarding/KYC, accounts, a debit card and core payments.
- Production neobank: $500,000–$1,000,000+ with lending, multiple products and a richer feature set.
- You don't build the bank: a sponsor bank holds the licence and deposits via a BaaS provider; you build the product.
- Cost is in compliance and the banking core — KYC/AML, accounts/ledger, card issuing — not the app screens.
- Run-cost matters more than build-cost: BaaS, KYC and card fees per account decide whether the unit economics work.
- Phase the MVP — one account, one card, core payments first; lending and extras later.
What a neobank is — and what you actually build
A neobank is a digital-first bank with no branches, delivered through a mobile app. But "building a neobank" rarely means building a bank. It means building four layers on top of a banking partner:
- Customer apps — iOS, Android, sometimes web. The experience customers see.
- Onboarding & identity — KYC/AML, document and identity verification, sanctions screening.
- Banking core — accounts, balances, a transaction ledger, statements. Usually provided by the BaaS partner, orchestrated by your backend.
- Card program — issuing virtual and physical debit cards, spend controls, real-time transaction notifications.
Around these sit fraud monitoring, support tooling, notifications and analytics. The budget is spread across all of them — see our fintech industry page for how these pieces fit together.
Build vs banking-as-a-service
This is the decision that sets the cost. Two routes:
Banking-as-a-service (BaaS) — you build on a provider that supplies accounts, cards and a sponsor-bank relationship via API (Unit, Treasury Prime, Stripe Treasury in the US; Solaris, Swan in the EU). You own the product; the bank owns the charter, deposits and core regulatory burden. This is how almost every modern neobank launches: fastest, cheapest, compliant.
Building your own banking core / pursuing a licence — multi-year, multi-million-dollar, and only rational at significant scale once the BaaS fees outweigh the cost of owning the stack. For a launch, this is the wrong route.
Cost breakdown by module
Indicative build costs for a BaaS-based neobank MVP, by module. Ranges vary with scope, market and partner.
| Module | Build cost | Notes |
|---|---|---|
| Mobile apps (iOS + Android) | $70k–$140k | Cross-platform or native; the visible product |
| Onboarding + KYC/AML | $40k–$90k | Vendor integration + flows; per-check fees separate |
| Accounts, ledger & BaaS integration | $60k–$130k | Orchestration, reconciliation, statements |
| Card program (issuing, controls) | $40k–$90k | Virtual + physical, notifications, limits |
| Payments (top-up, transfer, spend) | $30k–$70k | Rails depend on market (ACH/SEPA) |
| Support, fraud, ops tooling | $30k–$80k | The layer teams routinely under-budget |
That lands an MVP in the $250,000–$500,000 range. For how the app layer alone is costed, see our mobile app development cost guide; for payment specifics, our payment gateway integration guide.
Licensing and the sponsor-bank reality
In both the US and EU, moving money and holding deposits requires a licence — which the sponsor bank holds, not you. Through a BaaS provider, the chartered bank carries the regulatory obligation while you operate the brand and product. This single arrangement is the difference between launching in months and launching in years, and it is why neobank build cost is measured in hundreds of thousands rather than the tens of millions a charter implies. The deeper compliance backdrop is covered in our fintech app development guide.
Compliance and run-cost
Two cost streams continue after launch and decide viability:
- Compliance: KYC/AML verification and monitoring, transaction screening, dispute and chargeback handling, and the controls the sponsor bank requires. Mostly per-user and ongoing.
- Platform run-cost: BaaS platform and per-account/per-card fees, card scheme and processing fees, cloud infrastructure, and support.
Model these per-user before building. A neobank that wins customers but loses money on each account is in a worse position than one that scopes carefully and proves the spread first.
Timeline, team and MVP phasing
A BaaS-based neobank MVP typically takes 6–9 months. Crucially, BaaS/sponsor-bank onboarding, KYC vendor contracting and program approval run in parallel and are often the critical path — start them in week one. A typical team: product/delivery lead, mobile engineers, two backend engineers (one on the ledger/integration), QA with security skills, and part-time DevOps and compliance input.
Phase the MVP: onboarding + one account + a debit card + core payments first; defer lending, savings/interest, multi-currency, business accounts and rich personal-finance features to later. This keeps the first build in the $250,000–$400,000 range and gets you to market and to data faster. Many fintechs assemble the team through a dedicated development team to control cost.
How to control the cost
- Launch on BaaS — never build the bank for an MVP.
- Scope a tight MVP — one account, one card, core payments; defer the rest.
- Model run-cost first — unit economics decide viability more than build budget.
- Start partner & compliance onboarding in week one — it's the critical path.
- Choose a partner who has shipped a regulated fintech before — the operational layer is where inexperience gets expensive.
This is core mobile and custom software work; the right team and a phased plan are the main cost levers.
FAQ
How much does it cost to build a neobank in 2026?
A neobank MVP on a banking-as-a-service platform typically costs $250,000–$500,000 — apps, onboarding/KYC, accounts, a debit card and core payments. A broader production neobank with lending and multiple products runs $500,000–$1,000,000+. The cost is dominated by KYC/AML, the banking core and compliance, not the app screens. Ongoing BaaS and compliance fees are separate.
Do I need a banking licence?
Almost certainly not. Most neobanks run on a sponsor-bank model through a BaaS provider: the chartered bank holds the licence and deposits while you own the product. Getting your own charter is a multi-year, multi-million-dollar undertaking that only makes sense at significant scale.
What is the cheapest way to launch?
Build on a BaaS provider (Unit, Treasury Prime, Stripe Treasury in the US; Solaris, Swan in the EU) and scope a tight MVP — onboarding, one account, a debit card and core payments. That route typically lands at $250,000–$400,000 and is the fastest compliant path.
What drives most of the cost?
Compliance and the banking core — KYC/AML, the accounts/ledger layer, card issuing, transaction monitoring and the controls the sponsor bank requires — not the UI. Two apps with identical screens can differ several-fold in cost because of what sits behind a neobank's screens.
Can a startup afford it?
Yes, with a tight MVP on BaaS and a cost-efficient engineering partner. The bigger risk is unit economics, not the build budget — prove the spread between revenue and per-user cost before scaling features.
