APY and APR are two of the concepts that we most often see in the crypto world, especially in DeFi and in tools for staking and Bit2Me EarnAPR stands for Annual Percentage Rate (APR), while APY stands for Annual Percentage Yield. Both refer to the annual interest generated by a sum of money charged to borrowers or paid to investors, although as you'll see, each concept does so in a slightly different way.
Se is usually expressed as a percentage that represents the actual annual cost of funds over the term of a loan or income earned on an investment. This concept includes all commissions or additional costs associated with the transaction, but does not take capitalization into account. Thus, the APR often provides bottom-line information that they can use to compare between lenders, credit cards, or investment products.
What are APR and APY?
Now let's briefly explain both concepts.
Meaning of APR
Firstly, APY (Annual Percentage Yield) This is the effective return you'll earn in a year if interest is compounded (that is, if the interest earned is added to the principal and also accrues interest). For example, if you earn interest compounded on your investment several times a year, your actual return will be greater than simple interest alone. The APY reflects that compounding.
Meaning of APY
While, APR (Annual Percentage Rate), It is the simple annual interest rate applied to a loan or investment, without considering the capitalization of interest. This means it is calculated only on the original principal, without adding the interest earned to calculate new interest.
A simple way to differentiate them is:
- APY shows how much you will actually earn with compound interest.
- APR shows the base interest without compounding.
For example, if you have a loan with a 12% APR and the interest is compounded monthly, your actual APY will be slightly higher, around 12,68%, because each month the interest is calculated on a larger balance due to compounding.
In short, APY accounts for the effect of compound interest, while APR is just the simple rate applied over a year.
How to calculate APR and APY in crypto?
Now, let's see how we can calculate these two values in case we are participating in a crypto protocol where these concepts are used.
Formula for APR
The APR (Annual Percentage Rate) represents the cost or return on a loan or investment over a year, without considering the compounding of interest. This means that the APR measures only the annual simple interest, without adding the interest earned on previous interest.
The APR is calculated by multiplying the periodic interest rate (for example, monthly or daily) by the number of periods in a year:
APR=(Principal×nInterest + Fees)×365×100
Where:
- Interests: total interest paid or earned during the term.
- Commissions: additional related charges.
- Home: initial amount of the loan or investment.
- n: number of days of the loan term.
object lesson
Imagine you borrow €5.000 on a DeFi platform, and the monthly interest is 1%, with no additional fees. Then:
- Monthly interest = 1% of €5.000 = €50
- Term: 30 days (approximately 1 month)
We calculate the annual APR:
APR=(5.000×3050)×365×100=(150.00050)×365×100≈12,17%
This indicates that the annual cost or return without compounding is approximately 12,17%.
Formula for APY
The APY (Annual Percentage Yield) measures the actual return considering the capitalization of interest, that is, the interest earned generates new interest.
The APY is calculated by taking into account the periodic interest rate and the number of compounding periods per year:
APY=(1+nr)n−1
Where:
- r = nominal annual interest rate (expressed as a decimal, for example 0.12 for 12%)
- n = number of compounding periods per year (e.g., 12 for monthly)
object lesson
Continuing with the previous example, if the monthly rate is 1% (0,01), and it is compounded monthly (12 periods per year), the APY would be:
APY=(1+120.12)12−1=(1+0.01)12−1≈1.1268−1=0.1268=12.68%
This means that, at the end of the year, the effective return considering capitalization is 12,68%, slightly higher than the APR of 12%.
What is the difference between APR and APY?
Although the APR only takes into account simple interest, the annual percentage yield (APY) takes into account compound interest. Therefore, a loan's APY is higher than its APR. The higher the interest rate and, to a lesser extent, the shorter the compounding periods, the greater the difference between the APR and the APY.
Imagine the APR on a loan is 12% and the loan is compounded once a month. If an individual borrows €5.000, her interest for a month is 1% of the balance, that is, €50. That makes the balance increase to €5.050. The following month, 1% interest is applied on that amount, and the interest payment is €50,5, slightly higher than the previous month.
If you carry that balance through the year, your effective interest rate becomes 12,68%. Instead, the APY includes these small changes in interest expense due to compounding, while the APR does not, which is the main difference between the two concepts.
Cryptocurrency APR and APY Use Cases and Examples
Now, when we delve into the cryptocurrency world, we find that these financial concepts are capable of determining our profits or operating costs within the various sectors of the sector.
Although they may initially seem like similar terms, we can now clearly see their differences and applications, information that is vital for making informed decisions. That said, let's examine how APR and APY are applied in four key areas: staking, DeFi, trading and mining, accompanied by practical examples that will help both novices and experts better understand these indicators.
Staking: Rewards and Compound Growth
Staking is one of the most popular ways to earn passive income in cryptocurrency. It involves locking up tokens to support the security and validation of a Proof of Stake (PoS)-based blockchain network. Rewards are typically expressed in APY.
Why APY on staking? Because many platforms allow interest compounding: the rewards earned are automatically reinvested (or can be reinvested), generating a compounding effect. For example, if a network offers a 10% APY, and rewards are periodically added to the original stake, the effective return can grow beyond a mere 10% per year.
An illustrative example: if you stake 1000 tokens with a 10% APY, at the end of a year you will not only have those 100 reward tokens, but if the rewards are reinvested, the total will be higher thanks to compound interest. This mechanism incentivizes users to maintain and increase their stake to protect against currency inflation, thereby maintaining their stake in the network.
DeFi: Lending, Farming, and Variable Yield
In decentralized finance (DeFi), both APR and APY are crucial metrics, but they vary depending on the product type.
For loans and credits within DeFi protocols such as Aave o CompoundIt's common to see APR, as it reflects the actual annual cost without factoring in interest capitalization. For example, borrowing at a 12% APR means that's the actual interest you'll pay for the year, without reinvesting or adding interest on interest.
On the other hand, for yield farming or liquidity mining products, where users supply liquidity and earn periodic rewards, APY is often used, which reflects actual growth with compounding. If a protocol advertises a 15% APY, this indicates that your rewards will be reinvested and generate profits on profits, increasing the total return.
Furthermore, platforms like Bit2Me Earn They offer different APYs for staking various cryptocurrencies, maximizing profits through automatic interest accrual. Therefore, understanding whether an offer uses APR or APY is essential to properly assess the potential benefits or costs.
Trading: Indirect impact of APR and APY on strategies
Cryptocurrency trading itself is not directly measured by APR or APY, but these indicators can influence certain strategies.
For example, some traders employ leveraged trading techniques, where they borrow crypto to amplify their positions. Here, the APR on the loan is crucial for calculating costs and risks, as it represents the annual rate they must pay for those borrowed funds.
On the other hand, trading derivatives or participating in certain automated trading protocols may involve returns expressed in APY or APR, depending on the rules of each platform. Informed traders will consider these rates to optimize their net profitability, comparing potential gains with financing costs.
Mining: APR and APY in ROI
While traditional cryptocurrency mining (PoW) is primarily measured by profitability in terms of return on investment (ROI), APR and APY also become relevant when miners or investors use platforms that allow staking or lending to fund their operations.
For example, a miner can deposit mining revenue into DeFi platforms that offer APY to generate additional passive income. Or, they can take out loans with an APR to finance the purchase of hardware, with APR being the key metric for assessing the financial cost.
Additionally, some networks combine mining with staking mechanisms or variable rewards, where understanding APY rates helps estimate total returns. In short, APR and APY are part of the comprehensive calculation for assessing long-term mining profitability.
Advantages and disadvantages of APR
Advantages
- Simplicity and clarity: The APR is easy to understand because it represents a fixed annual rate without the hassle of compounding. This allows you to quickly determine the basic annual cost or return.
- Useful for loans: In credit or crypto lending transactions, the APR is commonly used so that the borrower knows the nominal rate without compounding surprises.
- Less volatility in calculation: By not depending on compounding frequency, the APR avoids complex variations that sometimes make it difficult to compare products.
Disadvantages
- Does not reflect compound interest: The APR does not take into account the effect of compounding interest, which can lead to an underestimation of the actual return on an investment or the total cost of a loan.
- Can be misleading for investors: By focusing only on the simple rate, the APR can be misleading for investors who expect increasing returns from reward compounding or yield farming in DeFi.
- Less competitive in displaying earnings: Some platforms that use only APR may appear less attractive compared to others that display APY, which better reflects actual earnings.
Advantages and disadvantages of APY
Advantages
- Incorporates compounding: The APY shows the actual return considering that the interest generated is reinvested and generates new interest, giving the investor a more accurate view.
- Best for investment products: When it comes to staking, farming, or deposits on DeFi platforms, APY is the most appropriate measure for estimating actual profits.
- Allows for real-world comparisons: The APY makes it easy to compare different products that compound interest at different rates, helping you choose the best options.
Disadvantages
- More complex to calculate and understand: For novice users, APY can be confusing due to the compounding formula and its variability based on compounding frequency.
- It can lead to high expectations: In volatile markets like crypto, APY can be temporary and change quickly, so a high APY isn't always sustainable over the long term.
- Less transparent on certain platforms: Some platforms may display an APY that includes variable rewards or additional incentives, which can make it difficult to interpret actual performance.
