Software Development Cost Calculator
Turn project complexity, platform scope, and team rate tier into a realistic hours and cost range — before you’re on a call with anyone quoting you a number.

How to use this tool
- Pick the complexity tier closest to what you’re building — a simple tool, a small business app, a full SaaS MVP, or an enterprise-scale system.
- Check any extra scope that applies: a mobile app on top of the web app, a public API for integrations, or an internal admin dashboard.
- Choose a team rate tier. Offshore, nearshore, and onshore rates differ by roughly 3–4x for the same hours, so this alone can swing the total more than complexity does.
- Read the range, not a single number — software estimates are inherently a range until requirements are locked down.
- Remember the estimate covers build hours only. Discovery, design, QA, and post-launch support are typically another 15–30% on top.
Every software cost estimate is really two separate numbers multiplied together: how many hours the work takes, and how much an hour costs. Most public “cost calculators” only let you adjust one of those, which is why they tend to either wildly lowball a project (using offshore rates against enterprise-scope hours) or wildly overstate it (using onshore rates against a simple tool’s hours). This calculator keeps both dials visible on purpose, because in practice rate tier moves the total further than complexity does — the same 500-hour project can cost anywhere from $12,500 to $90,000 depending purely on who’s building it and where they’re based.
The hour ranges here come from how these project sizes actually play out: a simple tool (a landing page, a single-purpose utility, a small internal script) typically runs 80–150 hours because there’s little state to manage and few edge cases. A small business app — auth, a handful of CRUD screens, one or two third-party integrations — moves into the 300–500 hour range because now there’s a real data model, permissions, and error handling to get right. A SaaS MVP (600–1,000 hours) adds subscription billing, multi-tenancy considerations, and enough polish to put in front of paying users. Enterprise-scale systems (1,800+ hours) bring compliance requirements, complex integrations, and the coordination overhead of a larger codebase and team.
The scope multiplier exists because mobile, API, and admin-dashboard work don’t just add their own hours — they add hours to everything else too. A mobile app isn’t just “the web app again on a phone”: it means a second UI to build and maintain, its own release process (app store review adds real calendar time even if it doesn’t add build hours), and often platform-specific bugs that never show up on web. A public API means designing a contract you can’t easily break once external developers depend on it, plus documentation and versioning. An admin dashboard is frequently underestimated because it looks simple on a mockup but needs the same auth, permissions, and data-integrity care as the main product.
Rate tier is where a lot of the sticker shock or sticker relief in software quotes actually comes from, and it’s not simply “cheaper is worse.” Offshore and nearshore teams can be excellent — the rate difference mostly reflects local cost of living and currency, not skill. What it does change is communication overhead (time zones, language, working hours) and, for some projects, how much hand-holding on requirements the team needs versus how independently they can run. Onshore rates buy tighter overlap with your own working hours and often faster iteration on ambiguous requirements, which matters more for an evolving MVP than for a well-specified, fixed-scope build.
Frequently asked questions
Why is the cost a range instead of one number?
Because at the stage most people use a calculator like this, requirements aren’t locked down yet. The range reflects that uncertainty honestly rather than pretending to a precision the estimate doesn’t actually have. It narrows once real requirements, wireframes, and a specific team are in place.
Does this include design, QA, or post-launch support?
No — the hours shown are build hours only. Discovery and requirements work, UI/UX design iteration, QA and testing, and post-launch support/maintenance typically add another 15–30% on top of the build estimate, depending on how much of that your own team covers versus outsourcing.
Why does rate tier matter more than complexity in some cases?
Because it’s a multiplier on every hour, not just some of them. Complexity changes the hour count; rate tier changes what each of those hours costs. A 3–4x rate spread between offshore and onshore teams can outweigh the difference between a small app and a SaaS MVP.
Is a lower rate tier actually lower quality?
Not inherently — the rate difference mostly reflects regional cost of living and currency, not skill level. What usually changes with rate tier is communication overhead (time zones, working-hours overlap) and how independently a team can operate on ambiguous requirements, not raw capability.
What should I do with this estimate?
Use it to sanity-check a quote you’ve received, or to scope a budget conversation before you talk to anyone. It’s a planning number, not a substitute for a real scoping conversation once you have specific requirements.
