I built Calcinova because I kept noticing the same problem every time I needed to check something like an SIP return or an EMI breakdown.
Almost every calculator online was either buried in ads, forced a signup, or belonged to a broker/bank pushing their own product on you afterward.
I wanted something that just gave me the number, fast, with a clear explanation of what it actually means, no sales funnel attached.
It started as one or two tools and grew from there. Along the way I kept adding whatever I personally needed next- tax calculators during filing season, a FIRE calculator when I started thinking about long-term goals, PPF and compound interest tools for basic planning. The whole thing is built solo, and every tool is something I actually use myself.
Would genuinely love feedback- like if something feels off/inaccurate on an existing one, tell me, I'll fix it fast.

Curious how you keep all these calculators accurate when tax slabs and interest rate rules change every year. Is that something you update manually or do you have any data feeds behind the scenes?

@fikretsama72370 Great question! It’s manual right now..I track Budget announcements, Central Bank rate changes, and interest rate updates and push changes as soon as they’re official. No automated data feeds yet, but honestly for something like tax slabs or government scheme rates, I’d rather verify and update myself than trust a feed that might lag or misinterpret a rule change.

Love how clean this is, no signup flow is a huge plus. One thing that would make it even better is adding a side-by-side comparison mode so you can pit two loan or SIP scenarios against each other on the same screen instead of opening multiple tabs.

@ethem_topr36430 Really appreciate that.. The side-by-side comparison idea is great like being able to pit two SIP scenarios or loan options against each other without juggling tabs is something I've been thinking about too. Adding it to the roadmap!

Love that there's no signup wall or upsell hiding behind a calculation. The no-clutter approach to something as dry as SIP and PPF math feels like a real design choice rather than laziness.

@oztrurk73771 Thanks, Duru! That was very much an intentional decision from my side as financial tools shouldn't make you sign up just to run a quick SIP calculation.

Finally a finance tool that doesn't shove an account signup down my throat. The SIP and EMI calculators gave me clean numbers in seconds, no ads or popups in the way.

@ameleksah89834 That’s exactly what I built it for, just the number, no friction in the way. Really glad the tools delivered that. More tools coming :)
