AROI (Annualized Return on Investment) is the metric expressing expected yearly return on an investment claim. It is used by Maclear and is calculated according to the formula: expected earnings are divided by the remaining period, scaled to a full year against the purchased principal. AROI standardizes returns across claims with different terms and prices, allowing their direct comparability. It does not guarantee future performance.
AROI, or Annualized Return on Investment, is a metric that evaluates the average yearly profitability of an investment in comparison to the initial cost. It helps translate the calculated return into a per-year rate that is simple to calculate. This makes AROI useful when a comparison of different investment projects across different timeframes is required.
AROI applies a simple annualization: it scales the expected return over the remaining holding period to a full year, without compounding or discounting cash flows over time. Annualized figures give a way to compare investment projects with different terms on a common yearly basis.
What does AROI stand for?
AROI stands for Annualized Return on Investment. This is a metric that calculates expected annual return on an initial investment claim.
In order to calculate AROI, it is necessary to divide expected earnings by the remaining period and then scale the result to a full year against the initial value of the purchased principal.
How AROI Is Calculated: the Formula and a Worked Example
The AROI formula shows how to calculate annualized return.
AROI is a simple annualisation: it scales the expected return over the remaining period to a full year. It does not compound or discount cash flows over time.
The worked example of calculating the return on a claim purchased at-par through AROI is presented below. The investor buys a claim with the following parameters — principal purchased equals €100; expected earnings and maturity equal €4; and the remaining period equals 90 days.
Step 1 of the calculation. Calculating daily expected earnings by Expected Earnings (4) divided by Remaining Period (90). 4/90 = 0.0444
Step 2 of the calculation. Annualize expected return on investment. AROI = 4/90 × 365/100 = 0.162, 16.2%
Illustrative only. Buying the same claim at a discount lowers the principal purchased, which raises AROI. Returns are not guaranteed.
If the investor purchases the same claim with a discount, AROI automatically increases due to the smaller value of a denominator in the formula. The Secondary Market article provides a detailed breakdown of par vs. discount.
Illustrative example only. Actual returns depend on borrower performance and platform fees and may differ materially. AROI is a forward-looking estimate and does not guarantee future performance.
How Is AROI Calculated?
AROI is calculated by using the formula: AROI = (Expected Earnings / Remaining Period) × (365 / Principal Purchased).
An illustrative worked example shows how AROI is calculated in a case where the principal purchased equals €100, expected earnings are €4, and the remaining period is 90 days.
AROI vs IRR, APR, APY, and NAR: What Each Metric Measures
The table below provides an overview of the return metrics that are used when evaluation of claims, loans, and investment portfolios is required. Each metric, AROI, IRR, APR, APY, and NAR, is applied in a different way.
Return metrics compared — AROI vs IRR, APR, APY and NAR.
Metric
Full name
What it measures
When it is used
Key limitation
AROI
Annualized Return on Investment
Annual expected return on the purchased principal, given the remaining period
Maclear's main metric for claim valuation (Primary & Secondary Market)
Simple annualisation; does not discount cash flows over time
IRR
Internal Rate of Return
Discount rate that sets the NPV of cash flows to zero
Projects or portfolios with uneven cash flows
Sensitive to timing and assumptions; more complex to calculate
APR
Annual Percentage Rate
Nominal annual rate without capitalisation
Consumer loans and rate quotes
Ignores reinvestment and compound interest
APY
Annual Percentage Yield
Annual return including capitalisation
Deposit and savings products
Assumes reinvestment; not always applicable to P2P
Each metric answers a different question. None is universally “better”; the right choice depends on the instrument, the cash-flow pattern, and what you are comparing.
Is AROI the same as APR and NAR?
No, AROI is not the same as APR and NAR.
AROI calculates an expected annual return on the principal by producing simple annualization that does not discount cash flows over time. This is how Maclear calculates returns. APR, however, calculates a nominal annual rate without capitalization and does not account for compound interest. NAR measures net annual returns after the losses and fees on an investment project and is retrospective and methodology-dependent.
Why Maclear Uses AROI for Secondary Market Claims
In the Secondary Market, AROI is a metric that is used to assess the claim before the purchase. The AROI calculation allows buyers to estimate the expected annualized return on the principal that will be invested, accounting for the remaining period of the claim. The buyers can estimate the returns from the moment of purchase onwards. AROI is also useful for the sellers as it reflects the interest accumulated up to the point of the claim’s sale.
At-par and discount contexts of the pricing make AROI a simple metric to assess the returns on claims without accounting for the complexity of premiums. Investors are capable of making weighed investment decisions based on the calculated annualized return rather than modeling a full cash flow.
How to Read an AROI Figure Without Misreading It
As one of the P2P return metrics, AROI gives a simple evaluation of the returns on the principal claim to help the investor understand the average yearly profitability of this investment. AROI does not discount cash flows over time. AROI does not account for:
1) A realized return on investment. AROI is the expectation, not a result.
2) The case of default, overdue, and partial repayment. AROI only evaluates expected earnings.
3) AROI does not discount money over time, unlike IRR.
4) Guaranteed returns on investment. Higher AROI usually implies higher risk, not a better investment.
Does a Higher AROI Always Mean a Better Investment?
No, a higher AROI does not usually mean a better investment.
AROI accounts for annualized expected returns on the principal and does not consider factors like risk, the project’s timeline, or default.
Key takeaways
AROI (Annualized Return on Investment) expresses the expected yearly return on a claim as expected earnings over the remaining period, scaled to a full year against the principal purchased.
The formula is AROI = (Expected Earnings / Remaining Period) × (365 / Principal Purchased); for a €100 claim earning €4 over 90 days, AROI is about 16.2%.
AROI is a simple annualisation: it does not compound and does not discount cash flows over time, unlike IRR.
Buying a claim at a discount lowers the principal purchased and therefore raises AROI; claim pricing is only at par or at a discount.
AROI is a forward-looking expectation, not a realised result; it ignores default, late or partial repayment, and does not guarantee future performance.
A higher AROI usually reflects higher risk or a longer term, not a safer or better investment.
FAQ
What does AROI stand for?
AROI stands for Annualized Return on Investment. It is a metric that calculates an expected average yearly profitability of an investment in comparison to its initial cost. AROI is used as a simple annualization without a discount on cash flows over time.
How is AROI calculated?
AROI is calculated as expected earnings divided by the remaining period, which is then multiplied by a full year divided by the value of principal purchased. The formula for AROI calculation is: AROI = (Expected Earnings / Remaining Period) × (365 / Principal Purchased)
What is the difference between AROI and IRR?
The main difference between AROI and IRR is that AROI is a metric that calculates the expected average annual profitability of an investment by comparing it with the initial cost by a simple annualization that does not consider the discount of the cash flow over time. IRR is a metric that calculates discount rate and eliminates the NPV of cash flows while being more sensitive to timing.
Is AROI the same as APR or APY?
No, AROI is not the same as APR or APY. APR measures the nominal annual rate without capitalization and is utilized to assess different consumer loans and rate quotes without taking into account compound interest and reinvestment. APY measures capitalization value and calculates annual return based on that value. Unlike APR, it assumes reinvestment and may measure investment that is not related to P2P. Meanwhile, AROI is a simple annualization of the expected annual returns on the purchased principal.
What is NAR, and how does it relate to AROI?
NAR is an industry-specific retrospective metric that calculates net annual return on investment after losses and fees. The NAR metric is used by a range of platforms in the industry, like Mintos. AROI is the main metric of claims assessment used by Maclear and accounts for the annual return in connection with the remaining period. NAR is a retrospective metric and requires a specific methodology, while AROI is a simple annualization that does not account for discounts on cash flow over time.
Does a higher AROI mean a safer or better investment?
No, a higher AROI does not mean a safer or better investment. AROI does not evaluate the impact of risk, default, or the timeline of the project, adjusting the expected return according to the evaluation of these factors. Instead, AROI offers a simple framework to compare different claims with varying terms and prices.
