Everything on CalculatNow is provided for general information and education. It is not professional advice, and it is not a substitute for a qualified human being who knows your situation.

1. What CalculatNow is, and what it is not
CalculatNow publishes free online calculators covering finance, real estate, health and fitness, math, and everyday tasks. Each calculator applies a published formula, or a rate or table from a public authority, to the values you enter. That is the whole of what it does.
A calculator is a tool for arithmetic, not a decision. It cannot see your medical history, your credit file, your dependants, your tax residency, your insurance cover, the condition of a property, or the hundred other facts that make your circumstances yours. Two people can enter identical numbers and receive an identical result while the correct course of action for each of them is completely different.
Use our results as a starting point for a better conversation with a professional. Do not use them as the conversation.
2. No professional relationship is created
Using this site does not create a doctor and patient relationship, an adviser and client relationship, an accountant and client relationship, an attorney and client relationship, an agency relationship, or a fiduciary duty of any kind between you and CalculatNow or anyone who writes for it.
We are not licensed to give you advice, and we are not holding ourselves out as licensed. We are not a bank, lender, mortgage broker, insurer, registered investment adviser, broker dealer, tax preparer, law firm, medical practice, appraiser, or real estate brokerage. Nothing on this site is an offer, a solicitation, or a recommendation to buy, sell, borrow, lend, insure, or invest in anything.
3. Health and fitness calculators
Our health calculators are not medical advice and are not a diagnosis. Tools such as BMI, BMR, TDEE, body fat, ideal weight, lean body mass, calorie and macro targets, heart rate, pregnancy and ovulation dates, GFR, A1C conversion, and blood alcohol content apply population level formulas to the figures you enter. Population formulas describe averages. They routinely misdescribe individuals.
Body composition estimates in particular are known to be unreliable for athletes and very muscular people, for older adults, for people with a great deal of muscle or very little, during pregnancy, for children and adolescents, and across different ethnic groups. A number that looks alarming may be meaningless for you, and a number that looks reassuring may be hiding something that matters.
Always seek the advice of your physician or another qualified health provider with any question you have about a medical condition, a symptom, a medication, a diet, a fasting protocol, or an exercise program. Never disregard professional medical advice, and never delay seeking it, because of something you calculated here. If you think you may have a medical emergency, call your doctor or your local emergency number immediately.
Two specific warnings. Our blood alcohol content calculator produces a rough estimate from a simplified model and must never be used to decide whether you are fit to drive, to operate machinery, or to work. Actual blood alcohol varies with factors the calculator cannot know, and it can continue rising after your last drink. If you have been drinking, do not drive. Our pregnancy, ovulation, and conception tools give date estimates only. They are not a form of contraception, not a fertility treatment, and not a substitute for prenatal care.
4. Financial, tax, and investment calculators
Our financial calculators are not financial, investment, or tax advice. Mortgage, loan, refinance, amortization, savings, compound interest, retirement, 401(k), IRA, annuity, inflation, income tax, payroll tax, capital gains, and net worth tools all produce illustrations, not quotes, offers, or filings.
- Loan and mortgage figures are illustrations. A real payment depends on the rate a lender actually offers you, your credit profile, the loan product, points, fees, escrow, and closing costs. Only a lender can quote you. Our results are not a pre approval, a commitment to lend, or a guarantee of any rate or term.
- Tax results are estimates. Tax law changes, brackets and thresholds are indexed, and credits, deductions, phase outs, state and local rules, filing status, and residency all move the answer. We state the tax year a calculator uses. We do not prepare, review, sign, or file returns, and our output is not a tax opinion. Confirm anything that affects a filing with a qualified tax professional or with the tax authority itself.
- Investment and retirement projections are not forecasts. They are arithmetic run on assumptions you supply, such as a rate of return or a rate of inflation. Real markets do not deliver a steady annual return. Past performance does not indicate future results, and no projection on this site should be read as a promise that any amount of money will be available to you at any future date.
- Currency, salary, and cost figures move. Exchange rates, wage rules, contribution limits, and benefit formulas change, sometimes with little notice. Verify time sensitive numbers at the source before you rely on them.
5. Real estate calculators
Our real estate calculators are not an appraisal, a valuation, an inspection, or investment advice. Cap rate, cash on cash return, rental property ROI, DSCR, gross rent multiplier, the 1 percent and 70 percent rules, BRRRR, house affordability, rent versus buy, PMI, closing costs, seller net proceeds, and property tax tools all rest on assumptions you enter about rent, vacancy, expenses, appreciation, and financing. Change one assumption and the conclusion can reverse.
Property tax results use state level average effective rates. Actual property tax is set locally and varies by county, city, school district, and special assessment district, and it is affected by assessment practice, assessment caps, exemptions such as homestead relief, and reassessment on sale. Two houses on opposite sides of the same street can be taxed differently. Always confirm the real figure with the county assessor or the taxing authority for the specific parcel.
Real estate transactions are legally significant and expensive to get wrong. Before you buy, sell, finance, or invest, engage a licensed appraiser, a licensed inspector, a real estate attorney, and a qualified accountant as appropriate for your jurisdiction.
6. Math, conversion, and everyday calculators
Our math, unit conversion, date, and everyday tools implement standard published methods, and we test them. Even so, results are displayed to a limited number of digits, floating point arithmetic introduces small rounding differences, and a tool cannot tell you whether the formula you picked is the right one for your problem.
Where a result feeds into engineering, construction, medical dosing, academic submission, legal filing, or anything else where an error carries real cost, check it independently before you use it. Quantities for materials such as concrete, paint, tile, mulch, and roofing are planning estimates that do not account for waste, irregular surfaces, site conditions, or local building code.
7. Where our numbers come from
We build on documented, named formulas and on data published by official bodies, and we cite our sources on the pages where they apply. Where a calculator depends on data that changes, we state the year or show when the page was last reviewed.
We cannot guarantee that a third party source was accurate when we read it, that it has not changed since, or that we have reflected every subsequent amendment. If an official source and this site disagree, the official source governs and we would be grateful if you would tell us at support@calculatnow.com.
8. Results are estimates, not guarantees
Every result depends on the accuracy and completeness of what you enter. A mistyped digit, a wrong unit, an out of date rate, or an assumption that does not hold will produce a confident looking answer that is wrong. The site cannot detect this, and it will not warn you.
We may correct, change, or withdraw any calculator, formula, or page at any time without notice. A result you saw previously may not be reproducible later.
9. No warranty
The site and everything on it are provided on an as is and as available basis. To the fullest extent permitted by applicable law, CalculatNow disclaims all warranties, whether express, implied, statutory, or otherwise, including any implied warranty of merchantability, fitness for a particular purpose, title, accuracy, and non infringement.
We do not warrant that the site will be uninterrupted, timely, secure, or free of errors, that defects will be corrected, or that any result, formula, or data set is accurate, current, or complete.
10. Limitation of liability
To the fullest extent permitted by applicable law, CalculatNow and anyone who contributes to it will not be liable for any loss or damage arising out of or connected with your use of, or your reliance on, this site or any result it produces. This includes direct, indirect, incidental, special, consequential, exemplary, and punitive damages, and it includes loss of profit, loss of savings, lost opportunity, business interruption, tax penalties or interest, loss of data, and personal injury, whether the claim is framed in contract, warranty, tort, strict liability, or any other theory, and whether or not we were told such loss was possible.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain liabilities, including liability for death or personal injury caused by negligence or for fraud. Where that is the case, the exclusions and limitations above apply only to the extent the law allows, and nothing in this disclaimer limits any right you have that cannot lawfully be limited.
11. Your responsibility before you act
You are solely responsible for how you use this site and for any decision you make. Before you act on a result, we ask you to do three things: check the inputs you entered, verify time sensitive figures such as rates and tax thresholds at the official source, and speak to a professional who is licensed in your field and your jurisdiction.
12. Local law and your circumstances
Many of our calculators reflect rules that apply in the United States, and some reflect a particular state. Tax law, lending rules, benefit formulas, employment rules, health guidance, and property taxation all differ by country and often by region within a country. If you are outside the jurisdiction a calculator was built for, treat the result as illustrative only.
13. Third party links and sources
We link to outside websites, including government and standards bodies, so you can verify our figures. We do not control those sites, we are not responsible for their content, accuracy, availability, or privacy practices, and a link is not an endorsement.
14. Changes to this disclaimer
We may update this disclaimer as the site grows and as the law changes. When we do, we will revise the date at the top of this page. Your continued use of the site after a change takes effect means you accept the updated version.
15. Contact us
If any part of this disclaimer is unclear, or if you believe a calculator is producing an incorrect result, please write to us at support@calculatnow.com. We take reports of calculation errors seriously and we would rather hear about a problem than not.
This disclaimer works alongside our Terms of Use and our Privacy Policy.
