# Health and Borrowing Power

### The health meter

The health meter indicates how close your Prime Account is to insolvency. If your health meter shows 100%, you have not borrowed any funds, and there is no risk of becoming insolvent. If your health meter shows 2%, your Prime Account is on the brink of insolvency. Depending on your constructed portfolio, this most likely means that a small price movement in your held or borrowed assets will make your Prime Account insolvent. The account gets liquidated at 0% health, which depending on the composition of assets has a minimum of 20% collateral ratio.

### Borrowing Power

Tokens available on DeltaPrime have different borrowing powers: If you deposit $100 USDC, you can borrow up to $500 USDC or AVAX before liquidation; but if you deposit $100 PNG, PTP or QI, you can't borrow anything against it. USDC has 5x borrowing power, PNG has 0x. 

To understand why different tokens have different weights, please read the [safety](https://docs.deltaprime.io/protocol/security#token-specific-borrowing-power) section.

As your Prime Account is cross-margin, your borrowing power is shared across tokens. For more information on how it's calculated, read the [health calculations](https://docs.deltaprime.io/prime-brokerage-account/health-and-borrowing-power/calculations) below. If you instead want a simpler way to interpret the health meter, read the [interpretation](https://docs.deltaprime.io/prime-brokerage-account/health-and-borrowing-power/interpretation). Lastly, you can play around with your own health meter in the [Health Playground](https://docs.google.com/spreadsheets/d/1wukyfAj641H4xBva6G1DVIzrauyn1sazYZoD1qGCcIo/edit#gid=479001345).
