Ecosystem Overview

Engineering Cost Calculator

A REST API that measures the Sync Tax, the real dollar cost of coupling and coordination overhead in software teams.

Get Started

Engineering Cost Calculator

The Engineering Cost Calculator puts a dollar figure on something every experienced engineer feels but nobody measures: the cost of coupling and coordination overhead. That is the Sync Tax.

Why this exists

Every software team slows down as systems grow. More dependencies pile up, more meetings appear, more context switching erodes focus, and people wait on each other before they can move forward. Teams adjust timelines, add headcount, or accept that delivery gets slower and more expensive over time.

But that cost isn’t inevitable. It’s measurable. And once you measure it, you can manage it.

What the tool does

The calculator is a REST API. You send basic team and delivery data, and it returns three numbers:

  • Sync Tax multiplier: how much coupling inflates delivery effort
  • Hours lost per feature: hours lost per feature to coordination overhead
  • Annual cost projection: the total dollar impact on your team

It’s designed so you can plug it anywhere. REST API, JSON responses, one call. And it supports MCP, so you can connect Claude, Cursor, or any AI agent directly.

The problem it solves

Engineering leaders and founders sense their teams are slowing down, but they can’t quantify the friction. When you can’t put a number on it, you can’t prioritize fixing it. Expensive structure accumulates until margin is already gone.

That missing number is the Sync Tax. And it applies whether you’re a founder wondering if a rewrite is worth it, a CTO justifying a redesign to stakeholders, a team lead choosing between features and debt, or an AI agent consuming team data to recommend structural changes.

Status

The Engineering Cost Calculator is available and under active development.

I’m actively refining the scoring model, improving cost projections, and expanding integration support. The core API is live and ready to use.

Engineering cost has been invisible on too many P&Ls. If you’re building a product company and you want to know what’s burning margin, this is the tool to start with.
