Every number that decides
whether your pricing works

CostPad models the full picture — costs, tiers, fees, free-tier drag, and growth — so you can see your real margin before you ship a price.

Core Simulator

Costs in. Prices set. Margin out.

The three panels you start with. Everything updates the moment you change a number.

Cost of Goods Sold

Track every cost the way it actually scales

Most cost calculators only do flat monthly numbers. CostPad separates three kinds of cost so your per-user math is honest.

Fixed monthly costs — hosting, databases, base subscriptions
Per-user costs — anything that grows with headcount
Per-unit costs — API calls, LLM tokens, metered usage

Pricing Tiers + Blended Economics

Set your tiers, see the blended truth

Define each tier with a price and the usage it allows, then let CostPad blend them against your user mix into one honest margin — not a best-case-tier number.

Beyond the basics

Two surfaces worth their own page

The dashboard builder and the local MCP server are the parts that make CostPad feel like a tool, not a spreadsheet.

Dashboard Builder

A free-form grid like Grafana, but for pricing. Drag, resize from any edge, and arrange twelve panel types into the view you actually use.

MCP Server

CostPad runs a local Model Context Protocol server, so Claude, Cursor, and other MCP clients can read your model and run scenarios in their own flow.

The full set

Every panel, one purpose each

No filler panels. Each one answers a question a founder actually asks.

Payment Fees

Model Stripe rates, fixed fees, international surcharges, and App Store cuts into a blended fee per subscription.

Free Tier Impact

See how many paid subs it takes to cover your free users, plus burn rate and coverage ratio.

Growth Viability

Project MRR, ARR, break-even month, and payback from churn, growth rate, and new subs per month.

Add-On Packs

Model upsells with price and COGS to see per-pack margins and how they lift overall revenue.

Monthly at Scale

Project economics across subscriber milestones with a configurable paid-to-free ratio.

Multi-Product

Run many products from one instance — each with its own data, dashboards, and brand.

User Mix

Set how many users sit in each tier and watch revenue and margin update live.

Dark + Light

A full token system — cool-slate dark and cool-white light, by toggle or system preference.
