Free AI Project Cost Estimator
Describe your project in one step and get an instant, AI-generated budget range — with a phase-by-phase cost breakdown, project risks, and a recommended tech stack. Free, no sign-up.
This free software development cost calculator is tuned for .NET, Blazor Server, ASP.NET Core, WPF, and modern web projects — including AI integrations. Estimates are based on real solo-contractor rates, so the numbers reflect what a project actually costs to build.
Describe your project once — the AI does the research, your estimate appears on screen and a PDF copy lands in your inbox

How the Cost Estimator Works
Describe your project
Write everything in one go — what you're building, key features, timeline, plus an optional tech stack and budget. Plain English is fine; the AI works out the rest.
AI builds your estimate
The estimate is generated against real contractor rate tiers and a six-phase delivery methodology, so every number is grounded — not guessed.

How the Estimate Is Calculated
Unlike generic calculators that multiply a single hourly rate by a guess, every estimate here follows the same methodology I use to quote real client projects.
Real contractor rate tiers
- $35–45/hr — standard tasks: CRUD modules, forms, reports
- $45–65/hr — complex and architecture work: multi-tenancy, real-time features
- $65–85/hr — specialist work: legal-tech integrations, AI features
Six delivery phases
Every project is split into Discovery & Planning, UI/UX Design, Core Development, Integrations & APIs, Testing & QA, and Deployment & Handover. Each phase gets its own hours and rate, and the phase cost is exactly hours × rate — so you can see where the money goes.
A range, not a fantasy number
The low end of your estimate is the exact sum of all phase costs. The high end adds a 20% contingency for scope creep and revisions — the most common reason software projects run over budget. If a phase doesn't apply to your project, it's zeroed out rather than padded.
Sample Estimate: Blazor Booking Web App
A typical output for a Blazor Server appointment-booking app with authentication, Stripe payments, and automated email reminders.
| Phase | Hours | Rate | Cost |
|---|---|---|---|
| Discovery & Planning | 12 | $45/hr | $540 |
| UI/UX Design | 24 | $45/hr | $1,080 |
| Core Development | 90 | $55/hr | $4,950 |
| Integrations & APIs | 30 | $65/hr | $1,950 |
| Testing & QA | 24 | $45/hr | $1,080 |
| Deployment & Handover | 10 | $45/hr | $450 |
| Estimated range (incl. 20% contingency) | $10,050 – $12,060 | ||
Software Project Cost FAQ
How much does custom software development cost?
It depends on scope and complexity. As a rough guide with a solo senior contractor: small internal tools run $3,000–$10,000, mid-size web applications $10,000–$40,000, and multi-module enterprise systems $50,000 and up. This estimator gives you a range tailored to your specific project instead of a generic bracket.
How accurate is an AI-generated cost estimate?
It is a planning-stage ballpark, not a binding quote. The estimate is grounded in real contractor rate tiers ($35–85/hr) and a six-phase delivery methodology, so the range is realistic for scoping and budgeting. A precise quote always follows a scope conversation.
Is this project cost estimator really free?
Yes — completely free, no sign-up and no credit card. You describe your project in a single step, see the full breakdown on screen, and receive the same estimate as a PDF in your inbox.
How much does .NET or Blazor development cost?
Solo senior .NET contractor rates typically range from $35/hr for standard work to $85/hr for specialist work such as legal-tech or AI integrations. A typical Blazor Server business application lands between $8,000 and $30,000 depending on modules, integrations, and timeline.
What information do I need to provide?
Just one description in your own words — what you want built, the features or problem to solve, and anything you already know about timeline or team. Optionally add your preferred tech stack and any budget you have in mind. One step, about a minute — no technical knowledge required.
Does the estimate include design, testing, and deployment?
Yes. Every estimate is broken into six phases: Discovery & Planning, UI/UX Design, Core Development, Integrations & APIs, Testing & QA, and Deployment & Handover — each with its own hours, rate, and cost.
Why do I get a cost range instead of a single price?
The low end is the exact sum of all phase costs. The high end adds a 20% contingency for scope creep and revisions — the most common reason real projects exceed their initial budget.
Can I hire you to build the project after estimating?
Yes. I am a freelance .NET Technical Lead with 8+ years of experience in Blazor, ASP.NET Core, and WPF, available for remote contract work with clients in the US, UK, Canada, and Australia. Use the estimate as a starting point and book a call from the results screen.
