Time poor, time rich
time leverage · buying back time
Choosing to be short of time now in order to own your time later. The trade only works in one direction: hours invested in something you own compound, and hours rented out do not, however well they are paid.
In practice
$200 an hour of output, $40 an hour to hand off. The spread is real only if the freed hours go to $200 work rather than to more $40 work.
The common mistake
Measuring the trade by the money spent. The cost is visible on a statement and the work it enabled is recorded nowhere, so a profitable trade reads as an expense.
Time arbitrage is exchanging time at one value for time at a higher one. It is the practical mechanism behind most changes in how much a person earns.
The basic trade
Hiring is the obvious case. If your time produces $200 an hour and you pay someone $40 to do work you were doing, you have bought back hours at a fifth of what they produce. The gain is the spread, and it only exists if you actually use the freed hours on higher-value work rather than on more of the same.
That condition is where the trade usually fails. Buying back ten hours and spending them on tasks worth $40 converts a good trade into a wash plus a management overhead.
The other direction
Time arbitrage also runs forward. Building something today that produces for years exchanges present time at today's rate for future time at a much higher one. A documented process, an article, a piece of software — each costs hours now and returns them repeatedly. See leverage and compounding.
It runs across contexts too. The same skill earns very different amounts depending on who is buying it, which is why the largest single income change most people make is a change of buyer rather than an improvement in capability. See career capital.
Working out your own number
Take what you want to earn annually, divide by roughly two thousand working hours, and you have an hourly figure. Any task available for less than that figure is a candidate to buy out, and the decision is arithmetic rather than a question of whether you can afford help.
Most people refuse the trade because the saving is visible and the gain is not. Paying $40 shows up on a statement; the $200 of work it enabled does not show up anywhere, so the decision reads as a cost. See hidden cost.
The limit
The trade requires demand for your higher-value hours. Buying back time with no pipeline waiting for it produces free time and a bill, which is why this works better as a response to being constrained than as a way to create capacity you have no use for.
What makes the trade sound rather than merely appealing is comparative advantage. Buying an hour for less than your hour produces is a gain even when you are better at the task than the person you bought it from — being better at something was never the argument for doing it. The spread is the whole mechanism, and it survives being worse at nothing.

What is time arbitrage?
Exchanging time valued at one rate for time valued at a higher one — buying back hours through hiring, or investing hours now in something that returns them repeatedly later.
How do you calculate what your time is worth?
Divide your target annual income by roughly two thousand working hours. Tasks available for less than the resulting figure are candidates to buy out, provided you use the freed hours on higher-value work.
When does buying back time not work?
When there is no higher-value work waiting for the freed hours. Without demand for them, the trade produces free time and a cost rather than a return.
