Distilled spirits calculator

True Cost of Distilled Spirits

What is the real energy, liver, sleep, and hydration cost of vodka, gin, tequila, rum, whiskey, brandy, and overproof pours? Pick the spirit, pour style, count, sex, and optional weight. The page updates the alcohol load, calories, water loss, rough-night risk, and clearance window in real time.

Input parameters

Choose your spirit

Change the spirit, pour style, count, sex profile, and optional weight. The details update instantly without forcing you to chase the result around the page.

Spirit category

Pick the spirit type first. The math keeps the same spirit formulas and swaps in the right ABV and roughness profile.

Pour format

Choose the pour style. A small change in volume can move the alcohol load quickly with spirits.

Estimated clearance window

For the selected Men profile, this session contains about 14 g of pure alcohol and may take around 1 hr 24 min to clear. REM may start about 10 to 20 min later, and the drink load may drive about 140 ml of water loss.

What you may notice

Spirits can feel sharp quickly because a small liquid volume can carry a big alcohol dose.

What your body is doing

Spirits move quickly, so a small glass can land harder than it looks.

Sleep terms in plain English

What REM delay actually means

REM stands for rapid eye movement sleep, which is the dream-heavy part of the night. Alcohol often makes you sleepy early, then pushes REM later and can leave the second half of the night more broken up. If you want the deeper background, use the REM overview, the Harvard sleep explainer, and the REM timing review.

1. You may fall asleep faster[5]

Alcohol can act like a short-term sedative, so bedtime can feel easier than usual.

2. REM starts later[4][5][6]

That is what the REM delay number means. The dream-heavy part of sleep gets pushed back.

3. The back half of the night gets rougher[5][6][10]

Once alcohol clears, the body often rebounds with a higher heart rate, lighter sleep, and more wakeups.

Rough-night guide

Why some spirit nights feel rougher than others

Spirit type changes both the alcohol load and how rough the night may feel. The table below keeps your pour size the same and shows how different spirit choices compare.

Current pick: Vodka

1. Darker spirits can feel heavier[7][8]

Aged and darker spirits usually carry more of the byproducts that can make the same alcohol dose feel rougher than vodka or other cleaner pours.

2. Spirits are easy to under-pour in your head[1]

A small glass can still carry a lot of alcohol. That is why spirits often feel stronger than they look compared with beer or wine.

3. Straight pours dry you out fast[1][9]

Spirits bring much less fluid with each gram of alcohol than beer or wine, so the dehydration bill climbs quickly even when the glass looks small.

Calculations

The math behind the page

These formulas drive the live results, and each card shows the exact numbers from your current selection.

Pure alcohol and calories[1]

Alcohol (g) = Volume (ml) x (ABV ÷ 100) x 0.789 Calories = Alcohol (g) x 7.1

Distilled spirits carry very little else nutritionally, so almost the whole energy bill is the ethanol itself.

Using your current selection

44.4 ml x 1 = 44.4 ml 44.4 x (40 ÷ 100) x 0.789 = 14 g 14 x 7.1 = 99 kcal

Water tax[9]

Water loss (ml) = Alcohol (g) x 10 Net hydration (ml) = Drink volume - Water loss

Spirits bring a small fluid payload, so the alcohol-driven water tax usually shows up fast.

Using your current selection

14 x 10 = 140.1 ml 44.4 - 140.1 = -95.7 ml max(0, 140.1 - 44.4) ÷ 250 = 0.4 glasses

Score = (sum of concentration x weighting factor) x (Volume ÷ 1000)

This page uses a transparent proxy score to show why darker spirits can feel rougher than cleaner pours even when the alcohol grams are similar.

Using your current selection

(4 x 5) + (2 x 3.5) + (1 x 2.5) + (10 x 4) + (18 x 1.5) + (0 x 1.2) = 96.5 96.5 x (44.4 ÷ 1000) = 4.3 pts
