Custom Software Cost Estimator

Most cost guides give you a wide range and leave you to guess where your own project actually falls in it. This tool narrows that down in under a minute, three quick questions about what you're building, and you get a real estimate range based on projects of similar scope, not a single generic number that applies to nobody in particular.

How It Works

Pick your project type, website, web app, mobile app, or AI automation, then how complex it genuinely is, and tick off the features you already know you'll need, accounts, payments, integrations, an admin panel. The estimator combines these into a range grounded in the same pricing logic covered in our full guide to custom software costs in the UK, not a number invented for this tool alone.

Why a Range, Not a Single Number

Any tool claiming to give you an exact price before understanding your actual requirements is guessing, and this one is honest about that. What it gives you instead is a genuinely useful starting range, grounded in real project data, enough to sanity-check a quote you've already received, or to walk into a first conversation with realistic expectations rather than a number pulled from thin air.

A precise number only comes from a real discovery conversation, where your specific requirements, integrations, and constraints get properly scoped. This estimator is the honest, useful step before that, not a replacement for it.

What Actually Moves the Number

Project type sets the baseline, a marketing website and a full SaaS platform sit in genuinely different cost brackets before anything else is even considered.

Complexity scales that baseline significantly, a simple, single-purpose tool costs meaningfully less than a platform with multiple user roles, real business logic, and several integrations, even within the same project type.

Specific features add cost individually and predictably, user accounts, payments, third-party integrations, an admin dashboard, and offline support each represent real, identifiable engineering work, which is why the estimator asks about them directly rather than folding them into a vague complexity guess alone.

In Practice

This estimator pairs directly with our complete guide to custom software costs, which covers the full reasoning behind these ranges, including fixed price versus time and materials, what's typically included and excluded in a quote, and how to tell a realistic number from an unrealistically cheap one. Our web platform development service is where the conversation continues once you're ready to move from an estimate to an actual scoped project.

The founders who budget well are rarely the ones who found the single cheapest quote, they are the ones who understood roughly what their project should cost before ever speaking to an agency, and used that understanding to evaluate every quote that followed against a real, informed baseline.
