The year-by-year breakdowns are genuinely useful, especially for the retirement calculator since you can see how contribution changes actually play out over time. Nice that everything just runs in the browser with no sign up.
@bondjames Thanks so much for this, Bond! The year-by-year view was actually one of those "let's just add it and see" features early on, so it's really encouraging to hear it's landing exactly where I hoped, retirement is the calculator where seeing the compounding play out over time matters most. I'm heads-down on more development right now to push this further (more scenario modeling, more of that "show your work" transparency across the other calculators too) so GetFinCalc keeps getting more useful, not just bigger. Appreciate you taking the time to try it out!
The formulas being right there on each calculator is a really nice touch, makes it feel like it was built by someone who actually cares about the math being right.
@sonkupu12462 Really appreciate you noticing that, Şükriye! That's honestly the whole point for me, financial tools that hide their math are the ones that lose people's trust, and I wanted GetFinCalc to be the opposite of that. Getting comments like yours is great motivation, I've got a lot more development in the pipeline to keep expanding the calculators and make the whole thing even more useful as a day-to-day tool. Thanks for checking it out and for the kind words!
