What it does

A free collection of investment and finance calculators focused on clarity and accuracy. Unlike many single-purpose or ad-heavy tools, all calculators are in one place and show transparent formulas, charts, and breakdowns. Supports multiple languages (EN/NL/FR/DE), works without accounts, and is built as an early-stage project with feedback-driven improvements.

Free investment calculator with compound growth, goal planning, and real S&P 500 historical backtesting. Model contributions, fees, and expense ratios.

This investment calculator is a free tool for estimating compound interest growth, planning savings goals, and testing ideas against historical S&P 500 returns. It is an investment calculator, a compound interest calculator, and an investment growth calculator in one place. It brings three calculators together on one page so you can compare a classic growth projection, a goal focused planner that estimates how many years it may take to reach a target, and an S&P 500 backtest that uses real market history. Enter a starting amount, choose how often you invest, and set an expected annual return. The calculator shows a growth chart and a yearly table so you can see how much value comes from…from investment-calculator.net

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
