The honest answer: anywhere from $6,000 to $500,000+, which is why "it depends" answers dominate this topic. But the reasons it depends are knowable, and once you understand them you can predict your own number within a sensible range.
This guide breaks down 2026 pricing the way an engineer scopes a build — by project type, team model, and the multipliers that actually move the quote. If you want a number for your specific project right now, the software development cost calculator runs this exact model interactively.
Cost by project type (2026 benchmarks)
These are typical full-production ranges quoted by US/EU agencies, based on the same Clutch/GoodFirms-style pricing data our calculator is anchored to:
| Project type | US/EU agency range | Solo senior engineer |
|---|---|---|
| Landing page + backend | $8k–25k | $4k–10k |
| MVP (auth, payments, core flow) | $30k–70k | $12k–28k |
| Full SaaS product | $60k–150k+ | $25k–60k |
| Marketplace (two-sided) | $80k–200k+ | $35k–80k |
| Internal tool / dashboard | $15k–50k | $7k–20k |
Two things explain the spread between columns:
- Overhead. An agency quote carries project managers, account managers, office costs, and margin — often 40–60% of the invoice never touches code.
- Geography. A senior engineer in Berlin or Austin bills $100–150/hr. An equally senior engineer in Dhaka or Warsaw bills $45–60/hr for the same stack and the same architecture rigor. That's cost of living, not skill difference.
The five factors that actually move your price
1. Feature scope — the big one
Auth, payments, admin panels, notifications, file uploads, third-party integrations: each is days-to-weeks of work. The difference between a $12k MVP and a $28k MVP is almost always the feature list, not the idea. Cut scope before you cut quality — a smaller product built properly beats a bigger one built badly, and you can always add features to a solid foundation.
2. Complexity class
A CRUD app over a database is simple. Real-time collaboration, heavy data pipelines, 3D rendering, or ML inference are complex — they multiply both cost and calendar. Most founders overestimate their complexity class: the majority of successful SaaS products are, architecturally, well-executed CRUD.
3. Who builds it
- Agency — highest cost, most process. Good when you need a large parallel team and contractual shields.
- Freelancer marketplace — cheapest hourly rate, highest variance. The $25/hr quote that takes 4× the hours isn't cheap.
- Solo senior engineer — one accountable person, no coordination overhead. The sweet spot for MVPs and products up to a few hundred thousand users, which is further than most products ever get.
4. Fixed price vs. time and materials
Fixed price transfers risk to the builder — which only works when scope is locked in writing before the quote. Time and materials is fairer for genuinely exploratory work but requires trust and weekly demos. Beware fixed-price quotes given without a scope document: one party is about to be unhappy.
5. What "done" includes
Deployment, monitoring, documentation, and post-launch support are part of shipping software, not extras. A quote that excludes them isn't lower — it's incomplete. Ask every bidder: what happens in the 30 days after launch?
Rules of thumb that hold up
- The build is ~60% of year-one cost. Hosting, maintenance, and iteration typically add 40–70% of the initial build cost over the first year.
- Rewrites cost more than builds. Rescuing a badly-built codebase routinely exceeds the cost of having built it properly — if your current build feels wrong, an architecture audit before more feature spend usually pays for itself.
- Speed comes from scope, not headcount. Adding developers to a small product slows it down (coordination cost). A 4–6 week MVP is realistic for one senior engineer with a locked scope — that's exactly how I run MVP builds.
