In-House vs Agency Development Cost Calculator

Q: Is a freelancer really the cheapest option?

On raw rate, often yes. But a low hourly rate moves project management, spec-writing and quality control onto your plate, which is why we add 15% overhead. It also concentrates risk in one person: if they disappear mid-build, continuity is on you. A freelancer is a strong fit for small, well-defined scopes; larger or business-critical builds usually justify an agency's structure.

Getting custom software built, and torn between hiring in-house, using an agency, or a freelancer? Sticker rates only tell half the story, hiring costs, ramp-up and coordination overhead swing the real total. Enter your project size and rates to see which model actually costs less.

How it works

The honest way to compare in-house vs agency development cost is to hold the work constant and price each delivery model fully. This tool fixes the project at a number of developer hours, then costs out three paths: hiring your own team, hiring an agency, and hiring a freelancer.

Agencies and freelancers are straightforward, hours multiplied by their rate. For a freelancer we add 15% on top, because a solo contractor shifts real coordination, spec-writing and QA work onto you that an agency would otherwise absorb. The in-house number is where the surprises live: it is not just salary during the build, but the recruiting cost to hire and the ramp-up month before anyone is fully productive.

Because in-house cost is fixed salary while agency and freelancer cost scales with every hour, small projects favour contracting and large, long-running builds tend to favour hiring, provided you keep the team busy after launch.

In-house = devs × (loaded salary ÷ 12) × months + (devs × $15k hiring) + one ramp-up month
Agency = hours × agency rate · Freelancer = hours × freelancer rate × 1.15
months = ⌈ hours ÷ (devs × 150 productive hrs/mo) ⌉

FAQs

Is it cheaper to build software in-house or with an agency?

It depends on project size. For a one-off build of a few hundred to a couple thousand hours, an agency or freelancer is usually cheaper because you pay only for hours delivered, no recruiting, no ramp-up, no idle salary. In-house tends to win on large, long-running products where a full-time team stays busy and fixed salary spreads across far more work than an hourly rate would cover.

What hidden costs make in-house development more expensive than it looks?

The hourly rate you'd pay an agency is visible; in-house costs are not. Beyond base salary you carry payroll taxes, benefits and overhead (a fully-loaded developer usually costs 1.25-1.4× base), recruiting fees to hire, a ramp-up period before anyone ships, and the risk of paying salary during gaps between projects. This calculator prices in hiring and ramp-up so the comparison is fair.
