About Us

ABV Calculators was created by people who actually brew. We got tired of clunky, ad-heavy calculators that made simple math feel complicated. So we built clean, fast, and accurate tools that any brewer can use without any confusion.

No signups. No popups. Just the numbers you need.

What We Offer 

Whether you are brewing beer, fermenting cider, making mead, or working on wine — our calculators give you accurate ABV estimates using Original Gravity and Final Gravity readings. We also cover attenuation, calorie estimation, and use the correct formula constants for each drink type.

Everything on this site is completely free to use.

Why Accuracy Matters to Us

Most online calculators use one formula for everything. We don’t. Wine fermentation works differently from beer, which is why our wine calculator uses the constant 136 instead of 131.25. Small detail — but it makes a real difference when precision matters.

Who Is This For?

First-time homebrewer or experienced craft brewer — it does not matter. If you ferment anything and want reliable numbers, this website was built for you.
