About Author , Founder of Calculate Online :
I’m Vrushabh Deshmukh, the person behind this website Calculateonline.org.
By background, I’m a Commerce graduate with a strong interest in finance and tech. I also work as a WordPress and Android developer, and I run Codebage, where I build digital tools and plugins.
This site came out of my own frustration, honestly. I was looking for some good calculators online especially for SIPs, solar savings, or simple finance tasks — but most of them were either clunky, too basic, or filled with ads. So I thought to build it for more user like me.
And that’s how Calculateonline.org started. Every calculator you see here is something I personally built not copied from anywhere. I try to make them simple, accurate, and actually useful, not just for myself but for anyone who needs them.
Thanks for stopping by.
If you find something useful here that makes my day.
