Project cost calculator

Software project cost calculator

I built this to give founders a planning range for a software project, not a vendor quote. Answer eight sizing questions, choose who would typically build the work, and you get a low, base, and high rough order of magnitude in USD.

Project sizing questions

What are you building?
Who would typically build this?

Labor market changes the hourly rate band. It does not change the estimated effort.

How many core workflows?
Who uses it?
What must it connect to?
Which platforms?
AI features?
Compliance needs?
Design readiness?

How the range is built

The calculator follows the same sequence I use when sanity-checking an early budget: size the work, convert size to effort, price the effort at a vendor rate band, then add overhead and contingency.

  1. Size drivers: project type, workflows, roles, integrations, platforms, AI scope, compliance, and design readiness.
  2. Effort: base developer-days by project type, adjusted by documented multipliers, capped to prevent runaway stacking.
  3. Rate: 2026 hourly bands for the labor market you select: agency vendors by region, or an individual freelancer / solo developer option.
  4. Overhead: 12% for solo freelancers and Asia direct hires, 20% for agency vendors (QA, project management, and DevOps).
  5. Contingency: 10% to 30% based on uncertainty such as vague scope, legacy integrations, regulated data, or missing designs. Clear focused MVPs start lower.

The result is a vendor-neutral industry ROM. It is useful for budgeting conversations before discovery. It is not a contractual quote.

FAQ

Is this a fixed quote?+

No. The calculator returns a rough order of magnitude planning range with low, base, and high figures. A fixed quote needs a written scope, acceptance criteria, and discovery on integrations and non-functional requirements.

Why does labor market change the price but not the effort?+

The questionnaire sizes the work in developer-days first. The labor market you select only changes the hourly rate band applied to that effort. Choose a vendor region, or pick individual freelancer for a solo developer planning band without agency markup.

Does AI cut the whole project cost in half?+

No. AI-assisted tools can speed up some implementation tasks, but review, QA, security, product clarification, and integrations still take human time. This calculator does not apply a blanket AI discount to the entire estimate. At most, a small discount can apply to the implementation slice for a very simple focused MVP.

Where do COCOMO and Function Points fit in?+

COCOMO II and Function Point Analysis are useful as a sanity check and for portfolio-level forecasting, especially when you have calibrated historical data. They are not enough alone for an early startup quote when requirements are still moving. This page uses a founder checklist instead of asking for KSLOC or story points.

Does the result map to a specific vendor package?+

No. The output is a vendor-neutral industry ROM based on size drivers, effort, overhead, and contingency. It is not tied to any single agency offer or catalog price on this site.
