Dry January Money Saved Calculator
Drinks per week
Count a standard drink: a 12-ounce beer, a 5-ounce glass of wine, or a 1.5-ounce shot. Four on a Friday and four on a Saturday is eight.
Average cost per drink
Count what you actually hand over. A beer at a bar is around $7, a cocktail closer to $14, a glass of wine poured at home maybe $3. Most people land somewhere in between.
Calories per drink
A 12-ounce regular beer is about 150 calories, a 5-ounce glass of wine about 120 to 125, a 1.5-ounce shot about 100, and a margarita about 170. Change the number to match what you actually drink.
Alcohol-free days
January has 31 days, so a full Dry January is 31 alcohol-free days rather than 30. Sober October is 31 too.
The four lines of arithmetic
- Drinks skippeddrinks per week divided by 7, times your alcohol-free days
- Money saveddrinks skipped times cost per drink
- Calories avoideddrinks skipped times calories per drink
- Annual savingdrinks per week times cost per drink times 52
Rounding happens on display only. The money and calorie figures come from the exact drink count, not the rounded one, which is why the defaults give $354 rather than $352.

The arithmetic behind the four numbers
Everything on this page comes out of four lines. Your drinks per week divided by seven gives a daily rate, and that rate times your alcohol-free days gives the drinks you skipped. Drinks skipped times your cost per drink is the money. Drinks skipped times your calories per drink is the calories. The yearly projection is drinks per week times cost per drink times 52.
Two conventions are worth stating plainly. The yearly figure uses a flat 52-week year, and it is independent of the challenge length, because it answers a different question: what a whole year at this drinking rate costs. Move the day count from 31 to 90 and that number will sit still. That is correct, not a glitch. The second convention is that rounding is applied at display only, so the money is worked out from the exact drink count rather than the rounded one.
The worked example, on the defaults: ten drinks a week is 1.43 drinks a day. Over 31 days that is 44 drinks you did not buy. At eight dollars each, $354. At 150 calories each, 6,643 calories. Keep the same habit off for a full year and the 52-week projection is $4,160.
Lighter drinker, same prices: four drinks a week over the same 31 days is 18 drinks, $142, 2,657 calories, and $1,664 a year. Heavier and out at bars: fourteen drinks a week at twelve dollars is 62 drinks, $744, and $8,736 a year.
One number this page deliberately does not print is a weight-loss estimate. Calories avoided is not the same thing as calories burned, the standard conversion people reach for is not reliable at an individual level, and putting a figure on it would be guessing dressed up as arithmetic. Money and calories are what the four inputs can honestly support.
Where the default numbers come from, and when to change them
The calorie default is 150. CDC defines a standard drink as a 12-ounce beer at roughly 150 calories, a 5-ounce glass of wine at roughly 120, or a 1.5-ounce shot of liquor at roughly 100. MedlinePlus, published by the National Library of Medicine, breaks it down further: regular beer 153, light beer 103, red wine 125, white wine 120, and 100 for a shot of 80-proof gin, rum, vodka, whiskey or tequila. Cocktails sit well above all of that, with a 4-ounce margarita at 170 and a 9-ounce pina colada at 490. The default of 150 is the beer figure because that is the drink most people picture, and it is within a couple of percent of the MedlinePlus number for the same serving. If you drink wine, set it near 120. If you drink cocktails, set it higher.
The cost default is $8. The median beer price from restaurant point-of-sale data puts the typical beer at $6.61, with bar beer generally running $6 to $9. Cocktails average closer to $14 across major US cities, with a $10 to $22 spread by market. Drinking at home is far cheaper than either. The latest Consumer Expenditure Survey splits household alcohol spending into $269 at home and $374 away from home across a year, which is roughly 42 percent at home and 58 percent out. Eight dollars is a blended average of that mix rather than a bar-only price, so raise it if you mostly drink out and drop it if you mostly drink at home.
The default of 10 drinks a week is above the population average, and it is worth saying so. Gallup's most recent reading has all US drinkers averaging 2.8 drinks in the past week, rising to about 4.9 among people who had at least one drink that week. Ten is the profile of the person who actually looks up a Dry January savings figure: someone drinking most nights, or four or five on a Friday and the same again on a Saturday. For reference, NIAAA's moderate-drinking ceiling is 14 a week for men and 7 for women, so ten is inside that band. If the average is closer to you, turn the default down and the numbers down with it.
The day count starts at 31 because January has 31 days, so a full Dry January is 31 alcohol-free days. The field runs from 7 to 365, which is the same range LockIn30 supports for a challenge, so whatever you set here you can actually run.
Turning a number on a screen into money in an account
The saving is notional until it moves. Nobody gets $354 richer by not going to a bar, because the money just stays in the checking account and quietly becomes something else. Two mechanics fix that. Set up an automatic transfer for the weekly figure, ten drinks at eight dollars is $80 a week, on the day you used to do your grocery run. Or move the per-drink amount by hand each time you would have ordered one, which is slower but makes the trade visible at the moment you are making it.
The other half is the habit. One month proves the spend is real. The annual figure only arrives if the month turns into a default, and that is a different problem from the arithmetic: it is about showing up on day 19 when nothing about it feels novel any more. A run you can see is easier to finish than one you are carrying in your head, which is why a day grid and a streak count do more work than they look like they should. LockIn30 runs a habit like this one as its own challenge, with "No Alcohol" already in the task library and a reminder you can set for the hour you usually pour one.
Before you start, the 30-Day Challenge End Date Calculator gives you a finish date and the milestone dates in between, and the Challenge Start Date Planner works backwards if you need to be dry by a particular date. While you are running, the 30-Day No Alcohol Challenge Tracker is the grid, and the Habit Streak Calculator sorts out your current and best streak if a day slips.
Frequently Asked Questions
Common questions about dry january money saved calculator
How much money do you actually save doing Dry January?
It depends on what you were drinking and where you were buying it. On the defaults here, ten drinks a week at eight dollars each across 31 days comes to $354. Drop it to four drinks a week and it is $142. Push it to fourteen drinks a week at bar prices of twelve dollars and it is $744. You will see $300 to $1,000 quoted a lot for a fully alcohol-free month. That spread is fair enough, but your own two numbers beat anybody else's average. For the baseline, the Bureau of Labor Statistics puts household spending on alcohol at $269 at home plus $374 away from home over a full year.
How many calories are in one drink?
CDC puts a 12-ounce beer at about 150 calories, a 5-ounce glass of wine at about 120, and a 1.5-ounce shot of liquor at about 100. MedlinePlus, from the National Library of Medicine, is more specific: regular beer 153, light beer 103, red wine 125, white wine 120, and 100 for a shot of 80-proof spirits. Cocktails are where it runs away from you, with a margarita around 170 and a pina colada around 490. The calculator defaults to 150, the beer figure. Wine or neat spirits, turn it down. Cocktails, turn it up.
How does the calculator work out the numbers?
Four lines of arithmetic, all of them printed on the page. Drinks per week divided by seven gives a daily rate, and multiplying that by your challenge length gives drinks skipped. Drinks skipped times cost per drink is the money. Drinks skipped times calories per drink is the calories. The yearly figure is drinks per week times cost per drink times 52. Only the displayed figures get rounded, so the money comes from the exact drink count rather than the rounded one. That is why ten drinks a week over 31 days shows 44 drinks and $354 instead of $352.
Why is the yearly figure not just the monthly one times twelve?
Because it answers a different question. The challenge figure is what this particular run saves you. The yearly figure is what a whole year at the same drinking rate would save you, worked out as drinks per week times cost per drink times 52 weeks. It deliberately stays put when you move the challenge length. On the defaults it reads $4,160, while twelve times the $354 on screen would be about $4,248. That gap is the difference between a 52-week year and twelve 31-day months.
How many drinks a week does the average American have?
Fewer than most people assume. Gallup's most recent reading has all US drinkers averaging 2.8 drinks in the past week, and about 4.9 among those who had at least one drink that week. The field defaults to ten because somebody looking up a Dry January savings figure is usually drinking more than the median, not less. NIAAA's moderate-drinking guidance tops out at 14 drinks a week for men and 7 for women, so ten sits inside that band. Set the field to what is true for you rather than what sounds respectable.
Does Dry January have to be 31 days, or January?
Thirty-one days is a full January, which is why it is the default here rather than 30. The arithmetic does not care which month it is. Sober October is the same 31 days, and a 60 or 90-day run works identically. The field takes anything from 7 to 365 days. If you want the finish date and the milestone dates on a calendar before you start, the 30-Day Challenge End Date Calculator works them out, and the Challenge Start Date Planner runs it backwards from a date you need to be ready by.
What if I drink one night partway through?
The arithmetic does not police you. Twenty-eight dry nights out of 31 still kept most of the money. Subtract the drinks you had from your weekly figure and rerun it if you want the honest number. If the unbroken run is the point for you, the 30-Day No Alcohol Challenge Tracker gives you a grid to tick off day by day, and the Habit Streak Calculator works out your current and best streak around the days you missed.
Is it safe to just stop drinking?
For most people, yes. For anyone physically dependent on alcohol, stopping abruptly can be dangerous and needs medical supervision rather than a calculator. If going without brings on shaking, sweating, seizures or hallucinations, talk to a doctor before you stop. The 30-Day No Alcohol Challenge Tracker covers that ground properly in its own FAQ. This page does money and calories, and it is not medical advice.
