Decision simulator (Monte Carlo)
Give it a real decision (rent vs buy, job A vs job B) with your real numbers, and it simulates 10,000 possible futures. It shows where they cluster and how bad the worst cases get. By Sunday, it is a tool on your machine for your own decisions.
05, Decision simulator: 10,000 futures for a real decision Difficulty: Advanced Time: Full day What it does: Give it a real decision (rent vs buy, job A vs job B) with your real numbers, and it simulates 10,000 possible futures. It shows you where the futures cluster, how bad the worst cases get, and which variable actually moves the outcome. Why build this The trap: deciding rent vs buy on ONE average scenario in a spreadsheet. The average scenario will never happen: interest goes up and down, markets move, your life moves. Monte Carlo simulation, one of the most powerful ideas in engineering and finance, replaces the single number with a distribution: you see the 10,000 versions of your future, not the one that flatters you. And you don't need to write the math yourself: Claude Code…
