How to Get Food for Free

Every month you spend $600 on food, you also invest $600. Whatever you eat, you match. The $600 sits in a diversified portfolio for six months. At a conservative 10% annual return, that batch grows by about $30 in that window. After six months, you take the $30. The $600 stays.

That last sentence is the whole thing.

The $600 stays.

When most people hear “investing,” they picture a one-time deposit that grows forever. That’s true, but it isn’t dramatic at the scale of a normal life. What is dramatic is what happens when you let a single $600 keep working every six months while you keep adding new $600s alongside it. The first batch never gets sold off. It gets pruned. The fruit comes off, the tree stays. Then it grows fruit again.

Now follow what that does over time.

You make your first deposit in January. The market does what markets do, which is shake around and roughly drift up. By July, that first $600 has grown to about $630. You take the $30. The $600 goes back in for another six months.

In August, your second deposit (the one from February) matures. Another $30. Then September. October. November. December. Through the rest of the year, $30 a month trickles in.

It’s nothing. A coffee. A side of fries. You almost don’t notice.

This is the part that loses most people. The first year doesn’t feel like progress. By December, you’ve recovered $180 against $7,200 of food spending. A 2.5% rebate. Your grocery store loyalty card does better than that.

But the river is filling.

In January of year two, the very first deposit you ever made comes due again. Same $600. Same gain. The fruit grew back.

But you also have a new batch maturing for the first time, the one you put in seven months ago. So January doesn’t give you $30. It gives you $60.

February: $60. March: $60.

Then July arrives. Batch one is on its third harvest. Batch seven is on its second. The batch from January of year two is hitting its first. That’s three checks in one month. $90.

By December of year two, you’re collecting three batches a month. $90 against a $600 bill. Still small. But you can feel something building underneath.

Here’s what people miss the first time they hear this. You didn’t add anything new to make it accelerate. You just kept doing what you were doing. The acceleration came from the principal staying put. Every batch, forever, pays out twice a year. You’ve been quietly building a portfolio of small annuities, six months at a time, without thinking of it that way.

Every six months, one more batch joins the steady harvest. Every year, two more.

Year three: by December, you’re collecting $150 a month. A quarter of the food bill, returned.

Year five: $270 a month. Almost half.

Year seven: $390 a month. Two thirds.

Year nine: $510 a month. You can almost taste it.

None of these are separate streams. It’s the same $600 you put in years ago, still working, still paying. Multiplied by every other $600 you put in alongside it. Each one a small annuity. None of them ever leaving.

This is where the chain breaks for most people. The numbers feel small relative to the time it’s taking. You compare them to what you could have done with the money. You move on to a different idea. The chain breaks. The clock resets.

But if you don’t break it, year ten happens.

Ten years in. Twenty batches mature in the same month. Twenty checks of $30 each.

$600.

That’s your food bill.

You walk into a grocery store. You fill the cart. The receipt that prints at the bottom is paid for, in full, by gains on principal you parked years ago. The portfolio writes the check. You eat for free.

It happens quietly. There’s no celebration, no notification, no banner across the top of an app. The math finally catches up. From this month forward, every batch you’ve ever put in keeps doing what it was already doing. Every six months, the same money pays you again. The harvest doesn’t care whether you’re paying attention.

Year eleven, the gains exceed the food bill. The portfolio pays for what you eat, and a little extra is left over. You’re net positive on eating.

Year twelve, more positive.

Year fifteen, your food spending is a profit center. The same activity that everyone else treats as an expense is, for you, a small income.

You did not win the lottery. You did not get lucky. You did one thing every month for ten years and refused to let the principal go.

This is not a hack. Not a budget trick. Not gymnastics. It’s the most ordinary fact about money applied to the most ordinary fact about life.

Money you don’t need today is supposed to work. Idle cash is a strange thing if you stop and look at it. It’s the only asset class that gets worse the longer you hold it. Inflation eats it. Time eats it. Doing nothing with money is paying someone to slowly take it from you.

Equity does the opposite. A share of a productive business is just stored labor that produces more labor while it sits. Fischer Black wrote about this fifty years ago, and it’s still the cleanest way to think about it. A share of a real company and a dollar in your checking account are not different in kind. One of them is paying you to hold it. The other isn’t.

What I’ve described is what wealthy families have always done with food. They don’t think of food as a cost. They think of it as something the dividends cover. It was never the price of food that made eating feel expensive. It was the assumption that every dollar of food spending had to come from a paycheck.

It doesn’t.

This is what we built Coinage to do. Connect your brokerage. Connect the card you actually use. Pick a portfolio. Match what you spend. The gains, every six months, get applied to the bills you would have paid anyway. The principal stays where it is, kept clean and growing, season after season. You keep eating, going out, traveling, living. The portfolio runs underneath all of it.

The ten-year line is real. It works for food because food is the cleanest expense to model. It also works for gas, rent, subscriptions, the gym, the streaming services, the things you barely register paying for. Anything you spend on, you can match. Anything you match, eventually pays itself.

The hard part is that nobody can do it for you. The chain has to stay unbroken. Principal stays. Gains harvest. Bills get paid by the harvest. The first year feels like nothing. The fifth year feels like progress. The tenth year feels like sorcery.

But it’s not sorcery. It’s just what money is supposed to do, finally allowed to do it.

Eventually the food is free.

Then it’s better than free.
