What is allocation of earnings?

Allocation of earnings is the decision about where each unit of income goes once it arrives. Income is limited and uses compete for it, so every share given to one purpose is unavailable to the others. Over time the pattern of allocation, more than the size of the income, decides what a household, company or fund can afford to do.

How it works

Earnings enter as a flow and are split across several destinations. Some destinations are fixed commitments such as rent, wages or debt payments. Others are discretionary, such as investment, reserves, or growth spending. The split depends on preferences, affordability, expected pay-off and prices, and it shifts when any of these change.

Allocation also feeds back on itself. Money put into investment can raise future earnings, while money spent on consumption cannot. A small change in the split, repeated every month, can lead to very different balances years later.

Example

Say a small company earns 100,000 per month. It allocates 60% to operating costs, 20% to investment in new equipment, 10% to a cash reserve and 10% to owner payouts, so 60,000, 20,000, 10,000 and 10,000. If it moves 10 points from payouts to investment, the investment line becomes 30,000 and payouts drop to zero. If the new equipment lifts monthly earnings by 5%, the shift pays for itself within a year or two; if it does not, the company has only starved its owners.

In a game economy, players split gold among currency sinks such as upgrades, repairs and cosmetics. A designer can read which sinks attract the largest share and adjust prices or rewards so that no sink is ignored.

How to model it in Machinations

Use a Source for the income, a Gate or several outgoing resource connections with set percentages for the split, and Pools or Drains for each destination. Make the percentages Levers, then Play many times and chart the Pools to compare how different splits change the balances over time.
