What StashGrid's tools are for, what they are not for, and where each one's limits sit.
Last updated: September 10, 2026
The core point
Every StashGrid tool is an estimator. It applies a published formula to the numbers you type in. It does not know your full situation, and it is not a substitute for a professional who does. Use the results to understand a problem and to sanity-check someone else's figures — not as the final word on a decision that matters.
General
The content and tools on stashgrid.site are provided for general informational and educational purposes only. While reasonable care is taken to keep formulas correct and reference data current, no representation or warranty is made as to accuracy, completeness, or fitness for any particular purpose. You use the tools at your own risk.
Results depend entirely on the values you enter. A small mistake in an input produces a confidently wrong output — the tool cannot tell the difference.
Not financial advice
The loan, mortgage, debt payoff, savings, retirement, salary comparison, travel budget, credit card, and paycheck tools do not constitute financial, investment, or tax advice, and StashGrid's operator is not a licensed financial advisor, accountant, or tax professional.
Real lending, tax and benefits outcomes depend on factors these tools do not capture: your credit profile, lender-specific underwriting, exact filing status, deductions and credits, local taxes, benefit elections, pre-tax contributions, and rules that change from year to year. Treat every figure as an approximation and confirm with your lender, payroll provider, or a qualified tax professional before relying on it.
Tax and paycheck data
Withholding and tax figures are based on published federal and state rates for the applicable tax year. Rates change, brackets are adjusted, and local or municipal taxes may apply that the tool does not model. A paycheck estimate is not a substitute for your employer's payroll calculation or a filed return.
Not medical advice
The BMI calculator and any other health-related tool are for general information only and are not medical advice, diagnosis, or treatment. BMI in particular is a crude population-level screening measure: it does not distinguish muscle from fat, and it can misclassify athletes, older adults, pregnant people, and people of different body compositions and ethnic backgrounds. Do not use it to make decisions about your health, weight, or diet. Speak to a doctor or a registered dietitian, who can assess you as an individual.
Lottery tools
Lottery draws are random. Number generators, frequency charts, "hot and cold" numbers, and historical result tables on this site do not improve your odds of winning. No method of selecting numbers changes the probability of any outcome, because each draw is independent of every draw before it.
These tools exist for entertainment and for looking up published results. Play only what you can afford to lose. If gambling is causing you difficulty, the National Problem Gambling Helpline is available at 1-800-522-4700.
Cryptocurrency and mining tools
The mining ROI calculator produces projections from current coin prices, network difficulty, and the hardware and electricity figures you supply. All of those change constantly, and difficulty and price movements can invalidate a projection within days. Nothing on this site is investment advice or a recommendation to buy, mine, or hold any cryptocurrency. Cryptocurrency values are volatile and you can lose your entire investment.
Live data and third-party sources
Some tools display data pulled automatically from external sources — lottery results, component pricing, coin prices. That data may be delayed, incomplete, or temporarily unavailable, and StashGrid does not control its accuracy. Where a page shows a "last updated" timestamp, check it before relying on the figures. Prices and availability shown for retail products are indicative only and change without notice.
Password and security tools
Passwords, keys, and hashes generated on this site are produced in your browser and are not transmitted or stored by StashGrid. Even so, treat any credential generated in a web browser with appropriate caution, and prefer a dedicated password manager for credentials protecting anything of real value.
Affiliate and advertising disclosure
StashGrid is funded by advertising and, on some pages, by affiliate or referral links. If you click such a link and sign up or make a purchase, StashGrid may earn a commission at no additional cost to you. Affiliate links are disclosed on the pages where they appear.
Commission does not influence the calculations. A tool's output is determined by its formula and your inputs, not by any commercial relationship. An advertisement or affiliate link is not an endorsement or a recommendation that a product suits your circumstances.
External links
Links to other websites are provided for convenience. StashGrid does not control and is not responsible for the content, accuracy, or practices of any external site.
Reporting an error
If a calculator produces a result you believe is wrong, please report it through the contact form with the inputs you used. Corrections are made promptly and are worth more than a complaint left unsent.
