Among all the concepts in Concrete vaults, eRate is often the most misunderstood.

Many users focus on their number of shares and expect that number to increase over time. When it does not, they may assume that nothing is happening.

In reality, eRate is where growth is reflected.

To understand this, start with the basics.

When you deposit into a vault, you receive shares that represent your ownership. The vault then deploys capital and generates yield. As this happens, the total value of the vault increases.

This total value is measured by NAV.

Now consider how that value is distributed.

Instead of issuing new shares to represent growth, the vault increases the value of existing shares. This is captured by the eRate.

eRate tells you how much each share is worth. When NAV increases, the value per share increases, and eRate rises.

This means your position grows even if your share count remains unchanged.

This approach has several advantages.

It simplifies accounting by keeping ownership stable. It also ensures that growth is distributed proportionally without requiring constant adjustments to share balances.

However, understanding eRate also requires understanding time.

eRate does not move in a straight line. It reflects the performance of underlying strategies, which can vary over time. There may be periods of slower growth or temporary fluctuations.

Over longer periods, however, eRate tends to reflect the cumulative effect of yield generation and compounding.

Compounding plays a key role here.

As returns are generated, they are reinvested into the vault. This increases NAV further, which in turn increases eRate. Over time, this creates a reinforcing cycle of growth.

Active management also influences eRate.

By reallocating capital and optimizing strategies, the vault can improve performance and drive higher NAV growth. This directly impacts the rate at which eRate increases.

For users, eRate provides a clear signal.

Instead of tracking multiple variables, you can focus on how the value of your shares evolves. This makes it easier to understand performance without getting lost in complexity.

In summary, eRate is not just a metric. It is the primary way growth is expressed in a Concrete vault.

Shares represent ownership. NAV represents total value. eRate shows how that value is distributed. Over time, as strategies perform and compounding takes effect, eRate increases.

Understanding this relationship is key to understanding how vaults work.
