A website cost calculator is the first thing a business opens when it decides to commission a build, and the second thing it learns is that every calculator asks the same four questions in different words. This page says what a website design cost calculator and a web design cost calculator are actually measuring, why a website price calculator or a web design price calculator asks about page count, custom design, e-commerce and integrations, and when the right counterparty is a software development agency rather than a web design shop. The free in-house versus agency worksheet on this site sizes the retainer against a hire; Retainvia Pro keeps the brief, the shortlist and the scorecard for $49 a month.
What the calculators measure
Pages, whether the design is custom or templated, whether the site sells anything, and what it must connect to. Those four drive the hours, and hours drive the price whatever the calculator shows. A business that writes those four answers down before opening any calculator has the first page of its brief, and can compare three agencies' quotes on the same basis instead of on three different assumptions.
Design shop or software development agency
A site that presents the business and takes an enquiry is a design shop's job; a site that runs a booking engine, a customer portal or a product with logins is a software development agency's job, and pricing it with a web design calculator understates it by the whole of the software. The U.S. Bureau of Labor Statistics handbook cited below puts the median pay of a marketing manager at $165,780 a year, which is the in-house owner of the build the free worksheet on this site compares against the agency's retainer.
The brief, the shortlist and the scorecard for a build
Brief the four answers, the launch date and what the business will do itself afterwards; shortlist three agencies that have built the same kind of site; score them on the quote against the brief, the launch date held and the site's performance in the first quarter. Retainvia Pro keeps that brief, the shortlist and the scorecard, with the retainer record of what was agreed and delivered, for $49 a month.
Questions people ask about website cost calculator
Why do website cost calculators give such different answers?
Because each assumes a different hourly rate and a different definition of a page; write the four answers down and compare quotes on them instead.
When do I need a software development agency instead of a web designer?
When the site does something for logged-in users: bookings, portals, products with accounts.
Should the build be a fixed price or a retainer?
A fixed price for the build against a brief, and a small retainer afterwards for changes; score each separately.
Does Retainvia estimate the build?
No. It keeps the brief, the shortlist, the scorecard and the retainer record for the agency the business chooses.
