APR vs. APY. Understanding Annualized Rates and Compounding Effects

September 23, 2024

Dive into the essentials of APR (Annual Percentage Rate) and APY (Annual Percentage Yield) and untangle the complexities of these crucial financial metrics.

Key takeaways:

  • APR and APY are essential metrics in DeFi for measuring ROI in staking, lending, borrowing, and providing insights into potential earnings and growth opportunities.
  • APR represents the baseline growth rate, while APY factors in compounding effects, offering a clearer picture of actual returns earned on crypto investments over time.
  • The frequency at which compounding occurs is a pivotal factor in determining the growth of your investments.

When considering different Yield Farming options in DeFi, two important terms are APR (Annual Percentage Rate) and APY (Annual Percentage Yield). At first glance, they may seem like similar profitability indicators for activities such as staking, lending, borrowing, and providing liquidity—however, the key difference lies in compounding- the reinvestment of interest. Unlike APR, APY takes compounding into account when calculating returns. Therefore, it is imperative to understand the difference between these two terms when deciding on an investment strategy in DeFiworld.

This is particularly relevant in protocols like Maya, where compounding can occur with great frequency (at every block!). Let's explore what these terms represent, their differences, and how they impact earnings.

APR vs APY: Understanding the Difference

Annual Percentage Rate (APR) represents the interest rate charged on a loan or earned on an investment without considering compounding effects. The past 30-day performance calculates APR; the line between the past date and the current date is the “APR.”

On the other hand, annual Percentage Yield (APY) reflects the annual rate of return accounting for the effect of compounding, which refers to the process where the earnings on an investment generate their own profits, providing a more accurate measure of total earnings or costs over time. In simpler terms, compounding is earning returns on both your original investment and on previous returns. 

Compounding frequency: The determining factor

The fundamental difference between APR and APY becomes apparent when considering the frequency of compounding. On platforms like Maya and THORChain, compounding is not annual, monthly, or even daily, but occurs with every block. Given that both protocols can experience up to 52.5M compounding periods per year, the effect on an investment’s yield is significantly magnified. 

How to calculate APY

To grasp the impact of such frequent compounding on yields, we will need to break down the process of converting an Annual Percentage Rate (APR) of 10% to an Annual Percentage Yield (APY). Follow these steps:

Applying this formula, we find that a 25% APR, with compounding at every block (approximately 5.25M times a year), yields a real return (APY) significantly higher than initially perceived. The frequency of compounding transforms the nominal APR into a more representative APY of the investment growth. 

Leveraging APY & APR in crypto investment strategies

This distinction is crucial when evaluating investment options. An APR of 20%, with compounding at every block, can, in reality, translate to an APY of 22.5%, offering a more accurate picture of the yield adjusted for compounding. 

Therefore, in environments with extremely frequent compounding, as is the case with Maya, APY becomes an indispensable metric for investors looking to maximize their returns. 

So mixing APY and APR effectively in a crypto investment strategy requires an understanding of how they can complement each other. Here are techniques that could prove beneficial if you’re looking to leverage both APR and APY: 

Strategic Yield Farming:

  • Utilize high-yield farming pools offering competitive APYs to maximize short-term returns.
  • Continuously monitor and reallocate assets across different pools to capture optimal APY opportunities.

Compound Interest Optimization:

  • Implement automated strategies to compound APR earnings at regular intervals.
  • Explore DeFi platforms offering dynamic compounding features to enhance long-term growth potential.

Risk-Adjusted Portfolio Allocation:

  • Diversify portfolio allocation between low-risk APR instruments and high-growth APY opportunities.
  • Conduct thorough risk assessments to ensure alignment with investment goals and risk tolerance.

Advanced Reinvestment Strategies:

  • Strategically reinvest APR-generated profits into high-yield APY protocols to amplify overall returns.
  • Employ smart contract-based automated reinvestment tools for efficient capital deployment.

Liquidity Pool Optimization:

  • Optimize dual LP positions by analyzing impermanent loss and adjusting asset ratios accordingly.
  • Utilize advanced trading strategies such as impermanent loss mitigation techniques to minimize risk exposure.

Dynamic Yield Curve Analysis:

  • Conduct in-depth analysis of yield curves across different DeFi protocols to identify optimal entry and exit points.
  • Leverage data analytics tools and algorithmic trading strategies to capitalize on yield curve fluctuations.
