"How much will an app cost?" is one of the first questions every business asks, and one of the hardest to answer honestly with a single number. The truthful answer is: it depends entirely on what the app actually needs to do — and most quotes that give a flat number without asking a single question about your features should be treated with suspicion.
This guide breaks down realistic mobile app development cost ranges in Bangladeshi taka for common app types, explains exactly what drives the number up or down, and covers the ongoing costs that catch businesses off guard six months after launch.
The short answer: a genuine MVP typically runs ৳80,000–180,000, a mid-complexity app with payments and real-time features runs ৳180,000–400,000, and a complex marketplace or on-demand platform starts around ৳400,000 and climbs from there. Every range below assumes cross-platform React Native development, not two separate native builds.
What Actually Drives the Cost
Screen count is a weak predictor of cost. Two apps with the same number of screens can differ in price by three times, because the real cost driver is almost never how many screens exist — it's what happens behind each one.
Backend Complexity
A screen that displays a static list costs far less to build than one that shows real-time inventory, calculates a dynamic price, or syncs data across multiple users simultaneously. The backend logic behind a screen, not the screen itself, is usually where the hours go.
Third-Party Integrations
Payment gateways, live maps, push notification services, and SMS verification each add integration work, testing time, and sometimes ongoing service fees on top of the development cost itself.
Design Complexity and Custom Animation
A clean interface built from well-established UI patterns is significantly cheaper than one with heavy custom animation and bespoke interaction design — both are valid choices, but they are not the same price.
Platform Choice: React Native vs. Fully Native
As covered in more depth in our React Native guide, sharing one codebase across iOS and Android rather than building two separate native apps is the single biggest lever most businesses have to control cost, both upfront and over time.
Cost Breakdown by App Type
| App Type | Typical Features | Price Range (BDT) | Timeline |
|---|---|---|---|
| Simple booking / informational app | Login, listings, booking form, push notifications | ৳80,000 – ৳180,000 | 4–7 weeks |
| E-commerce app | Product catalog, cart, checkout, payment gateway, order tracking | ৳180,000 – ৳400,000 | 8–12 weeks |
| On-demand delivery / service app | Real-time location, dual customer/rider apps, live order status | ৳350,000 – ৳700,000 | 12–18 weeks |
| Internal business / enterprise tool | Role-based access, offline sync, reporting dashboards | ৳250,000 – ৳600,000 | 10–16 weeks |
| Marketplace / multi-vendor app | Vendor onboarding, commission logic, multi-party payouts | ৳500,000 – ৳1,200,000+ | 16–26 weeks |
Ranges reflect typical BengalTech project scopes as of 2026 and will vary based on exact feature depth, design complexity, and agency. Treat this as a planning reference, not a binding quote.
React Native vs. Native: Cost Comparison
| Factor | React Native | Fully Native |
|---|---|---|
| Initial build cost | Lower — one codebase for both platforms | Higher — two separate codebases and teams |
| Time to launch both platforms | Parallel, typically faster overall | Often sequential unless two full teams run at once |
| 2-year maintenance cost | Lower — one codebase to patch and update | Higher — every fix built and tested twice |
| Best fit | E-commerce, booking, delivery, internal tools | Extreme performance or deep hardware-specific apps |
Hidden Costs Businesses Forget to Budget For
Backend Hosting & Servers
Ongoing server costs scale with users and data — a launch budget rarely accounts for what year two of real usage costs.
App Store & Play Store Fees
Apple charges an annual developer program fee; Google charges a one-time registration fee. Small individually, easy to forget when budgeting the whole project.
Push Notification & SMS Services
Third-party services for notifications and OTP verification typically bill per message or per active user once volume grows past free tiers.
Ongoing Maintenance
OS updates break things that used to work. Budgeting nothing for post-launch maintenance is the most common planning mistake we see.
How to Reduce Cost Without Cutting Corners
- Scope a genuine MVP first — one core feature done well, not ten features done half-well.
- Reuse an existing backend or admin system if one already exists for a web platform, rather than building a second one from scratch.
- Phase the rollout: launch with core functionality, add secondary features based on real user feedback instead of guessing upfront.
- Choose established UI patterns for v1 and reserve custom animation for after the app has proven demand.
Red Flags in a Quote
- A fixed price given before any real conversation about features — either padded heavily or missing scope that surfaces as change requests later.
- A price dramatically below every other quote you've received, with no clear explanation of what is being cut to hit it.
- No mention of who owns the source code and design files after the project ends.
- No separate line for post-launch maintenance, as if the app will need zero support after handover.
Frequently Asked Questions
What is the cheapest way to get a mobile app built in Bangladesh?
Scope a genuine MVP — the smallest version that solves one real problem for one type of user — and build it cross-platform with React Native. Skipping custom animation and building on proven UI patterns also keeps early cost down without hurting core usability.
Is React Native cheaper than hiring separate iOS and Android developers?
Almost always, both at build time and over the following two years of maintenance, since one codebase means one set of bugs to fix and one feature to build instead of two.
Do app development quotes in Bangladesh usually include Play Store and App Store submission?
This varies by agency and should always be confirmed in writing before signing. Some quotes include submission handling; others treat it as a separate line item, and the developer account fees themselves are always paid directly by the app owner.
How much should I budget for app maintenance after launch?
A commonly used industry benchmark is 15 to 20 percent of the original build cost per year, covering OS updates, bug fixes, and minor feature adjustments — budget for it from day one rather than being surprised six months post-launch.
Can I build just an MVP first and add features later without a full rebuild?
Yes, if the MVP is architected properly from the start with a real backend and clean data models. Problems only arise when an MVP is built as a disposable prototype never meant to scale, which then forces a rebuild once real usage begins.
Get a Number Based on Your Actual App, Not a Guess
Every range in this guide is a planning tool, not a quote. The only way to get an accurate number is to walk through your actual feature list, your integrations, and your timeline with someone who will ask questions before naming a price.
