# Alcohol Money Investment Calculator

Enter what you spend on alcohol, or what you'd stop spending if you quit, plus the yearly return you want to assume. The calculator treats that money as a deposit into an investment at the end of every month, then shows what the deposits could grow to over the years you choose. You also see how much of the total is your own money and what it would buy in today's dollars. Nobody can promise that return. Markets fall as well as rise, and fees, taxes and inflation all take a cut. Treat the result as an illustration only; it isn't investment advice.

These rows stay at 1, 5, 10, 20 and 30 years whatever span you pick. Today’s dollars use the inflation rate you entered.

## How the alcohol money investment calculator works

The calculator turns your spend into one deposit a month. A weekly figure becomes monthly at × 52 ÷ 12, because a year here is 52 weeks, the same as on the [alcohol spending calculator](https://sober44.com/tools/alcohol-spending-calculator/). A calendar year is a day or so longer, so the money you put in reads slightly low.

Each deposit goes in at the end of the month and grows at the yearly return divided by 12. That’s the standard future value of an ordinary annuity, the formula you’ll find in finance textbooks ([Tavangar, _Mathematics of Finance_](https://ecampusontario.pressbooks.pub/financemath/chapter/3-7-fv-of-annuities-formula-approach/)):

`value after n months = deposit × ((1 + monthly rate)n − 1) ÷ monthly rate`

At 0% there is nothing to divide by, so the value is the deposit × the number of months, which is exactly what you put in.

Take the example that loads with the page: $50 a week at 6% for 10 years. $50 × 52 ÷ 12 is $216.67 a month. The monthly rate is 0.5%, and 10 years is 120 deposits. After the last one the balance is about $35,507. Of that, $26,000 is your own money ($50 × 52 × 10) and $9,507 is growth.

The headline and the chart follow the number of years you pick. The table stays at 1, 5, 10, 20 and 30 years so you can compare spans side by side. The later rows show how much time does: at the same $50 a week and 6%, 30 years comes to about $217,645, and only $78,000 of that is money you put in.

## Picking a return you can live with

Nobody knows what future returns will be, so the rate you enter is a what-if. Long-run history gives some context. [NYU Stern’s historical return data](https://pages.stern.nyu.edu/~adamodar/New_Home_Page/datafile/histretSP.html) (Damodaran, updated January 2026) has $100 put into the S&P 500 at the start of 1928, with dividends reinvested, growing to about $1.16 million by the end of 2025. That’s roughly 10% a year, before inflation, fees and taxes, and it includes years like 2008 (−36.55%) and 2022 (−18.04%). Three-month Treasury bills averaged about 3.4% a year over the same stretch.

Cash earns far less. The [FDIC’s national average savings rate](https://www.fdic.gov/national-rates-and-rate-caps) was 0.37% as of September 21, 2026.

The default of 6% sits between those. It isn’t a forecast. The range card shows what a return 2 points lower or higher would do to the same deposits, an idea borrowed from the interest rate variance range in the SEC’s [compound interest calculator](https://www.investor.gov/financial-tools-calculators/calculators/compound-interest-calculator). As [Investor.gov](https://www.investor.gov/introduction-investing/getting-started/five-questions-ask-you-invest) puts it, every investment carries some degree of risk. This page doesn’t recommend any investment, account or fund.

## Inflation, fees and taxes shrink the headline number

A dollar in 10 years buys less than a dollar today. The today’s-dollars figure divides the future balance by (1 + inflation) once for every year. The default is 2%, the [Federal Reserve’s goal for inflation over the longer run](https://www.federalreserve.gov/faqs/economy_14400.htm). At 2%, the default $35,507 buys about what $29,128 buys now. Even at a 0% return, 10 years of $50 a week ($26,000) is worth about $21,329 in today’s money. The deposit stays the same dollar amount every month; it isn’t raised as prices rise.

Fees come off the return every year, and they add up. In the [SEC’s example](https://www.investor.gov/introduction-investing/general-resources/news-alerts/alerts-bulletins/investor-bulletins/updated), $100,000 growing 4% a year for 20 years ends at about $208,000 with a 0.25% annual fee, $198,000 with 0.50% and $179,000 with 1.00%. That’s why the rate box asks for the return after fees.

Taxes are left out because they depend on the kind of account and your own situation. So read the headline figure as an upper-middle case rather than something to count on. This is an illustration, not investment or tax advice.

## Making the money actually go somewhere

Money you don’t spend on drinks doesn’t invest itself. Left alone, it tends to leak into everything else. A common fix is an automatic transfer into a separate account on the day you’d have spent it, say payday or Friday, so the number on this page has somewhere to land.

If you carry debt, compare its interest rate with the return you typed in. Each dollar that pays down a balance charging more than that rate saves more in interest than the same dollar is assumed to earn here. That’s plain arithmetic rather than advice, and what fits depends on your own situation.

For a running total, [Sober44](https://sober44.com/#download) estimates the money you’ve saved since your quit date from your weekly spend, which gives you a figure to move each week. The app doesn’t invest anything itself, and everything stays on your phone.

## Frequently Asked Questions

Common questions about alcohol money investment calculator

### How much would I have if I invested the money I spend on alcohol?

That comes down to the amount, the number of years and the return you assume. At $50 a week and 6% a year, the calculator's default, you'd put in $26,000 over 10 years and could end up with about $35,507. Over 20 years that's $52,000 in and about $100,109 out. At 0% you'd have exactly what you put in. None of these returns is guaranteed.

### What rate of return should I use?

Nobody knows future returns, so treat the rate as a what-if. History helps a little. NYU Stern's historical data (Damodaran, updated January 2026) has $100 put into the S&P 500 with dividends reinvested at the start of 1928 growing to about $1.16 million by the end of 2025. That's roughly 10% a year compounded, before inflation, fees and taxes, and it includes years like 2008 (−36.55%) and 2022 (−18.04%). Three-month Treasury bills averaged about 3.4% a year over the same stretch. The FDIC's national average savings rate was 0.37% as of September 21, 2026. The default 6% sits somewhere in the middle of those, and the range line shows what 2 points either way would do. As Investor.gov puts it, every investment carries some degree of risk.

### Does the calculator allow for inflation?

Yes. The "in today's dollars" figure divides the future balance by (1 + inflation) raised to the number of years. The default is 2%, the Federal Reserve's goal for inflation over the longer run. Prices have risen faster than that in some years, so it's worth trying 3% too. At 2%, $35,507 in 10 years buys about what $29,128 buys today. Even at a 0% return, inflation shrinks $26,000 to about $21,329 of today's buying power.

### What about fees and taxes?

Enter your return after fees, which matter more than they look. In the SEC's example, $100,000 growing 4% a year for 20 years ends at about $208,000 with a 0.25% annual fee, $198,000 with 0.50% and $179,000 with 1.00%. Tax on gains depends on the kind of account and your situation, so the calculator leaves it out. This is an illustration, not investment or tax advice.

### How does the calculator work out the numbers?

Your spend becomes a monthly deposit: $50 a week × 52 weeks ÷ 12 = $216.67 a month. Each deposit goes in at the end of the month and grows at the yearly rate ÷ 12 (0.5% a month at 6%). The balance after n months is deposit × ((1 + monthly rate)^n − 1) ÷ monthly rate, and at 0% it's simply deposit × n. A year counts as 52 weeks, like the site's spending calculator, so ten years of $50 a week is $26,000 of your own money. Depositing weekly with weekly compounding would come out slightly higher, about $90 more over 10 years in the default example, mostly because each deposit starts growing sooner.

### How long does it take money to double?

The Rule of 72 gives a quick estimate: divide 72 by the yearly return. At 6% that's about 12 years, and at 8% about 9 (St. Louis Fed). It's meant for a lump sum. With regular deposits the balance grows faster than that, because you keep adding to it.

### What if I'm cutting back instead of quitting?

Enter only the part you'd stop spending. Halving $50 a week means investing $25 a week, which gives about $17,754 after 10 years at 6%, exactly half the full figure. To plan the step-down itself, the [alcohol taper schedule calculator](https://sober44.com/tools/alcohol-taper-schedule-calculator/) turns a start and a date into a daily drink target.

### Can Sober44 track the money I save?

Yes. Enter your weekly spend in Sober44 and it estimates the money, drinks and calories you've avoided since your quit date, along with a sober-time counter and health milestones. It doesn't invest money or project investment returns. Moving the money into savings or an investment is up to you, and this calculator shows what that could be worth. There's no account, and everything stays on your phone.
