About this tool

How this estimate works

Software project costs are determined by four main levers: the number of features (scope), the complexity of each feature, the hourly rate of the team, and how much urgency compresses the timeline. This estimator uses typical market rate ranges for development, design, and support across UK/Europe, US, and nearshore teams, then applies multipliers for complexity and timeline pressure to produce an order-of-magnitude range.

How costs break down in a typical project

For a medium-complexity web application, roughly 60–70% of budget is engineering, 20–25% is design (if included), and 10–15% is project management and QA. Support retainers are scoped separately. Infrastructure (hosting, domains, third-party APIs) is not included in these estimates — for most web apps, monthly running costs are £50–£500/month depending on scale.

Why UK/US rates differ from nearshore

UK-based and US-based developers typically charge £80–£200/hour depending on seniority and specialisation. Nearshore agencies (Eastern Europe, Latin America, South-East Asia) typically charge £30–£60/hour. The nearshore option can reduce total cost by 40–60% but requires stronger project management, clear specs, and timezone overlap planning. For highly regulated industries (fintech, health) the additional management overhead often narrows the savings gap.

These estimates reflect agency or freelance network rates, not in-house hiring costs. Hiring a full-time senior engineer costs £70,000–£120,000/year in total employment cost in the UK, which for a 6-month project works out to £35,000–£60,000 — plus recruitment, onboarding, and the risk that a single-person team creates a bus factor of one.

FAQ

Frequently asked questions

How accurate are these estimates?
These are order-of-magnitude estimates — accurate to within ±40–60% for most projects. A full project estimate requires a detailed specification, user stories, and usually a discovery sprint. Use these ranges for initial budget conversations and board-level planning. Request a formal quote from ruxox (or any development firm) for a binding figure.
Why does timeline pressure increase cost?
Compressing a timeline requires parallel workstreams, larger teams, and overtime — all of which add cost. A project scoped for 6 months will cost 20–30% more if delivered in 3 months. It also increases the risk of technical debt and QA gaps because there is less time for iteration. If budget is constrained, it is almost always more efficient to extend the timeline than to cut quality.
What is included in "ongoing support"?
A typical support retainer covers bug fixes, minor feature additions, dependency updates, server monitoring, and a guaranteed response time for incidents. It does not cover major new feature development (which is scoped as a new project). The 12-month retainer estimate is approximately 25% of the build cost per year — a common rule of thumb in the industry.
Is there a minimum project size ruxox takes on?
ruxox typically works on projects starting at £8,000. Smaller projects (under £5,000) are usually better suited to no-code/low-code tools or freelance platforms. For a free scoping estimate with no commitment, email app@ruxox.com or use the contact form.
