Why we show ads
MasterCalculator.in is free for everyone, with no sign-up, no paywall and no limits. Advertising pays for hosting, development and keeping our calculators up to date with new rules every year.
Our promise: ads never affect results
- Independent results. Advertisers have no influence on our formulas, results, articles or rankings. A calculator gives the same answer whether or not ads are shown.
- Clearly labelled. Every ad on our pages is marked "Advertisement" and kept visually separate from the calculator and its results.
- No endorsement. Showing an ad doesn't mean we recommend the product or service. Please do your own research before buying or investing.
- No paid reviews. We do not publish paid reviews or sponsored calculators. If we ever publish sponsored content, it will be clearly labelled "Sponsored".
How we keep ads out of your way
We design our ad placements so you can always use the calculators comfortably:
Never inside the calculator
No ads between input fields, buttons or results, so you can't tap one by mistake.
No pop-ups over your work
Full-screen ads may appear only between page visits, never while you're using a calculator, and can always be closed.
Fast pages
Ads load after the page is ready, so calculators open instantly. Space is reserved so the page doesn't jump around.
Fewer ads on phones
On small screens we show fewer ads, spaced well apart, and none above the calculator.
Ads may appear under the page title on larger screens, below the calculator, within and after the explanatory article, in the sidebar on larger screens, and as a small banner along the bottom of the screen. We don't show ads on this page or our other policy pages.
