About HazeGrid

HazeGrid is owned and operated by DustyHive LLP, registered in India. GST: 08AAFYD9620MIZK. All our calculators are 100 percent free to use, with no signup or paywall.

What we do

HazeGrid offers free, accurate finance calculators for India. From EMI and SIP, to income tax, salary, GST, FD, PPF, and NPS, every tool on the site implements the same formulas used by banks, mutual funds, and the Income Tax Department. Each result page also explains the underlying math and links to a focused blog post for deeper context.

Why we built it

Most finance calculator sites in India are cluttered with popups, lock users behind email gates, or push them to apps. We thought a clean, fast, no signup site that respects your time and attention would be a more honest way to help people make small but important money decisions. HazeGrid started as a side project at DustyHive LLP and has grown into a full library of tools.

How we keep it free

HazeGrid is supported by display advertising through Google AdSense. We do not sell user data, we do not run sponsored calculators, and we do not embed affiliate links inside our results. Ads are clearly marked and limited so that the calculators remain easy to use.

How we choose what to publish

Every calculator on HazeGrid is reviewed by an editor before launch. We cross check the formulas against published references from the Reserve Bank of India, the Income Tax Department, the GST Council, the National Pension System Trust, and the Pension Fund Regulatory and Development Authority. When tax laws or interest rates change, we update the affected calculators within a reasonable window and note the update on the page.

Editorial standards

Our blog posts follow a few rules. We do not promote any specific product, broker, mutual fund, or scheme. We avoid clickbait headlines and exaggerated claims. We prefer working examples grounded in Indian rupees, Indian tax law, and the kinds of decisions a typical Indian household actually faces. If we make a mistake, we correct it promptly.

Who runs it

HazeGrid is built and maintained by the team at DustyHive LLP. The editorial team brings together engineering, finance, and writing backgrounds. We work out of India and write for an Indian audience first.
