The compounding row is the difference between this and simple interest at the same rate - it is what reinvesting actually buys you, and on short holds it is smaller than most people expect.
The Weekly Yield Report

You have just modelled years of compounding at a fixed rate. Real rates are not fixed, and knowing where they sit is the harder part.

Every Thursday: where crypto yield actually is - stablecoins, liquid staking and DeFi lending, with the risk named next to the rate and what changed since last week.

What compounding frequency is actually worth

Daily compounding at 4.5% produces an effective 4.60% against 4.50% compounded annually. On $10,000 over a year that is about $10. Worth having, not worth choosing a riskier venue for - and a great deal less than most marketing implies.

Where compounding does matter

Time and contributions, not frequency. The same $10,000 at 4.5% for twenty years roughly doubles; adding $200 a month over the same period matters far more than whether interest lands daily or monthly.

The cost nobody models

In DeFi, compounding is not automatic. Claiming and reinvesting a reward is a transaction, and on mainnet the gas can exceed the reward on a small position. Auto-compounding vaults exist for this reason and charge a fee for it - worth comparing that fee against what you would spend doing it by hand.
