# The Earning Formula

Everything in Cash City's economy flows from one formula. Understanding it is the difference between playing casually and playing optimally.

***

## The Formula

```
Your Earnings = (Your Total Efficiency / Network Total Efficiency) × Epoch Emissions
```

That's it. Your share of each epoch's $CASH distribution equals your share of the network's total Efficiency. If you control 1% of the network's Efficiency, you earn 1% of emissions.

## Breaking It Down

### Your Total Efficiency

This is the sum of all Efficiency generated by your operation:

* Every seated Intern contributes its base Efficiency (100 for Common through 20,000 for Mythic)
* Advisor boosts multiply your total by their percentage
* Active consumables temporarily boost individual Intern Efficiency

**Example:**\
8 seated Interns averaging 600 Efficiency each = 4,800 base Efficiency\
With a Rare Advisor (+5%) = **5,040 total Efficiency**

### Network Total Efficiency

The combined Efficiency of every player in the game. This number grows as more players join, buy packs, and seat Interns. It's the denominator in the formula — and it's always moving.

### Epoch Emissions

The fixed pool of $CASH is distributed every 15 minutes. At 10,000,000 daily emissions, each epoch distributes approximately **104,167 $CASH**.

## Worked Example

Suppose you have 50,000 total Efficiency and the network has 5,000,000 total Efficiency:

```
Your share: 50,000 / 5,000,000 = 1%
Per epoch:  1% × 104,167 = 1,042 $CASH
Per day:    1,042 × 96 = ~100,000 $CASH
```

Now suppose 1,000 new players join and the network Efficiency doubles to 10,000,000:

```
Your share: 50,000 / 10,000,000 = 0.5%
Per epoch:  0.5% × 104,167 = 521 $CASH
Per day:    521 × 96 = ~50,000 $CASH
```

Your absolute Efficiency didn't change, but your share halved because the network grew. This is why the emission scaling model (increasing total emissions as firms grow) exists — it counteracts this dilution at the macro level while keeping the competitive dynamics intact.

## What This Means Strategically

The proportional model creates several important dynamics:

**Growth is survival.** Standing still while the network grows means your earnings shrink. Every player has incentive to keep reinvesting.

**Efficiency per $CASH matters.** At 200 $CASH per Intern Pack with an expected value of \~600 Efficiency, each token spent translates to a predictable (if variable) return rate. The optimal play is always the action that adds the most Efficiency per $CASH burned.

**Timing matters.** Early in the game's life, when the network is small, each unit of Efficiency represents a larger share. Players who establish early get a compounding advantage as their Efficiency share translates to more $CASH, which they reinvest into even more Efficiency.

**Whales are visible.** Since everything is proportional, a player with 1,000,000 Efficiency in a network of 10,000,000 is earning 10% of all emissions. The leaderboard isn't just a vanity metric — it's a direct readout of earnings share.
