About GrowMoneyy
GrowMoneyy exists to make everyday money math simple, fast, and free. No logins, no paywalls, no spreadsheets - just clear answers to real questions like "what will actually land in my paycheck?"
Who runs this
GrowMoneyy is an independent site created and maintained by Shivam Rai - a personal-finance and markets enthusiast who builds his own algorithmic trading and investing systems and verifies every tool here by hand. It started from a simple frustration: most online calculators are cluttered, out of date, or hide the real math. GrowMoneyy is the opposite - transparent, current, and genuinely useful.
More about Shivam RaiHow we build our calculators
- Official sources only. Tax logic is based on published figures from the IRS, the Social Security Administration, and each state's revenue department - updated for the current tax year.
- Sources are shown. Each calculator links to the primary sources behind its numbers so you can verify them yourself.
- Your data stays yours. Calculations run entirely in your browser. We never see or store the salary or figures you enter.
- Reviewed and dated. When tax rules change, we update the tools and note when they were last reviewed.
How we keep the numbers current
We re-check the figures behind every calculator against their primary sources - the IRS, the Social Security Administration, Freddie Mac's weekly rate survey, the FDIC, and each state's revenue department - on a monthly schedule, and sooner when a law or rate changes. The "Data verified" stamp on each page is the date of the last completed check. It moves only when we actually re-verify - never automatically.
An honest disclaimer
Our tools give estimates for educational purposes - they are not financial, tax, or legal advice, and they can't capture every personal detail. For decisions that matter, confirm with a qualified professional or the official source.
