# Vibemath

Vibemath is a web-based calculator for AI coding economics.

## Purpose

Help users compare the real monthly cost of AI-assisted software development across:

- coding subscriptions
- direct model APIs
- self-hosted local hardware
- rented cloud GPUs

## Audience

- developers
- indie hackers
- technical founders
- CTOs
- teams evaluating AI coding workflows

## What the tool models

- monthly lines of code or app-equivalent output
- work hours per month
- accepted LOC per hour
- parallel AI workstreams
- context-heavy token consumption
- subscription quotas and overage
- self-hosted amortization and electricity
- productivity penalties for weaker local models
- break-even points between different delivery setups

## Important terms

- `tokens per net LOC`: total tokens consumed per accepted line of code, including context and output
- `productivity multiplier`: quality-adjusted throughput factor for the selected model
- `home-hosted cost`: monthly amortization plus variable electricity cost
- `saved local profile`: browser-stored calculator state
- `share URL`: query-string encoded calculator state
