Annual Effective Rate
The annual effective rate (EAR), also called the effective annual rate, is the true interest rate for a year once the effect of compounding is included. When interest compounds more often than once a year (monthly, daily), the EAR is higher than the stated nominal rate — because you pay (or earn) interest on interest within the year. It is the honest way to compare instruments with different compounding conventions.
Two loans can quote the same nominal rate and cost different amounts, purely because of how often interest compounds. The annual effective rate strips that ambiguity out — it answers "what does this actually cost (or yield) over a year, compounding included?" For CRE borrowers and investors comparing debt, deposits, and returns, EAR is the apples-to-apples measure. (This defines the concept — Linton Global Solutions does not advertise interest rates.)
Nominal vs. Effective — the Core Idea
- Nominal (stated) rate: The quoted annual rate, ignoring intra-year compounding
- Effective annual rate (EAR): EAR = (1 + i/n)n − 1, where i = nominal rate and n = compounding periods per year
- The gap: A 6% nominal rate compounded monthly ≈ 6.17% EAR; compounded daily ≈ 6.18%. More frequent compounding = higher effective rate
- Direction: For a borrower, higher EAR = more cost; for an investor/depositor, higher EAR = more yield (that's APY)
EAR vs APR vs APY
- EAR: Pure compounding-adjusted rate — no fees included
- APR: A disclosure rate that folds in certain fees but (in the U.S.) typically does not compound — so APR and EAR differ. See APR
- APY: The deposit/investment version of EAR — same compounding math, framed as yield. See APY
- All-in cost: Neither EAR nor APR captures everything; the true all-in cost adds points, caps, and reserves
Why It Matters in CRE
- Comparing debt quotes: Convert competing loans to EAR (and then all-in cost) so compounding conventions don't distort the comparison
- Floating-rate loans: ARMs compounding monthly carry a higher EAR than the coupon suggests
- Return math: EAR/APY logic underlies IRR and time-value analysis on a deal
- Mezzanine / accruing debt: Interest that accrues and compounds (e.g., PIK) makes EAR materially higher than the coupon
A Quick Worked Example
- Loan A: 7.0% nominal, compounded monthly → EAR ≈ 7.23%
- Loan B: 7.1% nominal, compounded annually → EAR = 7.10%
- Takeaway: Loan B's higher nominal rate is actually the cheaper effective rate — the compounding frequency flipped the ranking
- Rule: Never compare a monthly-compounding loan to an annually-compounding one on nominal rate alone

Frequently Asked Questions
What is the annual effective rate (EAR)?
The annual effective rate is the true annual interest rate once compounding is included: EAR = (1 + i/n)^n − 1, where i is the nominal rate and n is the number of compounding periods per year. When interest compounds more than once a year, the EAR is higher than the stated nominal rate because you pay or earn interest on interest within the year.
How is EAR different from the nominal rate?
The nominal rate is the quoted annual rate ignoring intra-year compounding; the EAR accounts for it. For example, 6% nominal compounded monthly is about 6.17% effective. The more frequently interest compounds, the larger the gap. EAR is the honest, apples-to-apples way to compare rates with different compounding conventions.
What is the difference between EAR, APR, and APY?
EAR is the pure compounding-adjusted rate with no fees. APR is a disclosure rate that folds in certain fees but in the U.S. typically does not compound, so it differs from EAR. APY is the deposit/investment version of EAR — the same compounding math framed as yield. None of them capture the full all-in cost of a loan, which also includes points, rate caps, and reserves.
Why does EAR matter when comparing CRE loans?
Because two loans with similar nominal rates can cost different amounts due to compounding frequency. A 7.0% loan compounding monthly (≈7.23% EAR) can be more expensive than a 7.1% loan compounding annually (7.10% EAR). Converting quotes to EAR — and then to all-in cost — prevents compounding conventions from distorting the comparison, which matters most on monthly-compounding floating-rate debt.
Who can help me compare financing on an effective basis?
Michael R. Linton at Linton Global Solutions normalizes competing loan quotes to their effective rate and all-in cost of capital on Florida CRE deals, so borrowers compare true cost rather than nominal coupons.

Article Summary
The annual effective rate (EAR) is the true yearly rate with compounding included: (1+i/n)^n − 1. More frequent compounding makes EAR exceed the nominal rate (6% monthly ≈ 6.17%). EAR differs from APR (fees, usually no compounding) and equals the loan-side of APY. It matters in CRE because compounding frequency can flip which of two loans is actually cheaper — so normalize quotes to EAR, then to all-in cost. Mike Linton compares FL financing on an effective basis.
Key Takeaways
- ✓EAR = (1 + i/n)^n − 1 — the compounding-adjusted annual rate.
- ✓More frequent compounding → EAR above the nominal rate.
- ✓APR ≠ EAR (APR adds fees but usually doesn't compound).
- ✓APY is the deposit/yield version of the same math.
- ✓Compounding frequency can reverse which loan is cheaper.
- ✓Normalize quotes to EAR, then to all-in cost.
