Notes on AI tooling prices, how Forecost's estimates are calibrated, and guides for budgeting AI-assisted projects.
Stop Relying on Cheap AI Subscriptions: How to Prepare for Usage-Based Pricing
The flat $20 AI plan you lean on today is a subsidized on-ramp, not a stable destination. Here's why metered pricing is coming, and the skills and habits to build before the meter becomes the main event.
How to Estimate Runtime AI API Costs Before You Have a Single User
Runtime AI cost is the line item most founders forget until real users show up. Here's a six-input framework for building a defensible estimate before you've shipped anything.
Subscription Seats, API Usage, or Hybrid: Choosing Your AI Coding Purchase Plan
A cost estimate tells you how much you'll spend. A purchase plan tells you what to actually buy. Here's how the three strategies work and which signals point to each one.
AI Unit Economics 101: Will Your AI Costs Eat Your Margins?
If your product calls an AI model at runtime and you charge users for it, two numbers decide whether you have a business: cost per user and break-even price.
Why “Complexity” Is the Single Biggest Lever in Your AI Build Cost Estimate
Two MVPs with nearly identical feature lists can land 5x apart in AI build cost. The difference is almost always complexity and AI coding intensity — not the feature count.
Greenfield vs Brownfield: How Your Codebase Changes AI-Assisted Build and Maintenance Costs
Adding the same feature costs more in a five-year-old codebase than in a brand-new repo — and AI agents don't erase that gap. They often pay it in tokens instead of hours.
How to Not Bleed Tokens When Building With AI Coding Agents
Agentic coding tools bill the same task very differently depending on how you use them. Seven habits that keep AI build costs near the low end of the range instead of the high end.
Budgeting in the Era of AI: Why “Dev Hours × Rate” Isn’t Enough Anymore
AI-assisted development broke the old budgeting formula. Here's the three-number framework — build, maintenance, and runtime AI cost — that replaces it.
Claude Code vs Cursor vs GitHub Copilot vs Windsurf: AI Coding Tool Pricing Compared (2026)
A side-by-side look at what the most popular AI coding tools actually cost per developer per day — seat fees, included usage, and where the bill can blow up.
The MVP AI Cost Estimate Checklist: What to Know Before You Start Building
A practical checklist for turning a rough app idea into a useful AI build, maintenance, and runtime cost estimate.
Runtime AI Cost: The Bill Most Teams Forget Until After Launch
How to think about the monthly API cost of AI features before real users start generating real usage.
How Agencies Should Quote AI-Assisted Software Projects
A quoting framework for agencies building with AI tools or delivering products that include AI features.
Your AI Budget Does Not End at Launch: Planning Monthly Maintenance Cost
Why AI-assisted products need an ongoing maintenance budget for bug fixes, prompts, models, dependencies, and support workflows.
AI Discovery vs Manual Estimate: Which Forecost Flow Should You Use?
When to start with an AI-read project brief, when to use the manual wizard, and how to combine both for a better estimate.
