Before you write

You may find your answer faster in our FAQ:

My calculation looks wrong. What should I check first?
Common causes: (1) interest rate entered as percentage vs decimal — we use percentage (12, not 0.12); (2) tenure in years vs months — check the field label; (3) compounding frequency mismatch in older calculators. If the numbers still look wrong, email bugs@finsiderai.com with the URL and your inputs — we'll investigate within 24 hours.
Can you build a custom calculator for me / my company?
Possibly — email partnerships@finsiderai.com with your use case. We've built custom calculators for businesses that need branded tools embedded in their own sites.
Can I republish your calculators on my site?
No, our content is copyrighted and not licensed for republication. However, you're welcome to link to our calculator pages. For licensing inquiries, email legal@finsiderai.com.
Do you offer financial advice?
No. FinsiderAI is a calculation platform, not a financial advisory service. We don't recommend specific funds, stocks, or investments. For personalized advice, consult a SEBI-registered investment advisor (RIA) or chartered accountant.
I want to advertise on FinsiderAI. Who do I contact?
All advertising on FinsiderAI runs through Google AdSense. We don't sell direct ads at this time. If you're interested in sponsored content (clearly disclosed), email partnerships@finsiderai.com.
Is there a phone number I can call?
Not currently. We're a small remote team and email gives us time to respond carefully. For urgent security issues, email security@finsiderai.com — we monitor that inbox closely.
For users in India: If your inquiry is about a specific Indian tax provision, please mention the Section number (e.g. 80C, 87A) — it helps us reply faster.
