Effective annual rate

EAR = (1 + r / m)ᵐ − 1

r is the nominal annual rate and m is the number of compounding periods per year. The panel also derives periodic and monthly equivalents.

How to use

  1. Enter the nominal annual rate as a percentage.
  2. Set the number of compounding periods per year.
  3. Review the effective annual rate, periodic rate, and monthly equivalent.

Example

Input: Nominal rate = 8%, Compounding = Quarterly (m = 4)

Output: EAR ≈ 8.24%, Periodic rate = 2.00%, Monthly equivalent ≈ 0.64%

Under the hood, the calculator leans on r is the nominal annual rate and m is the number of compounding periods per year. the panel also derives periodic and monthly equivalents.—that’s why we surface the full expression (“EAR = (1 + r / m)ᵐ − 1”) directly above the interactive widget. When you embed that formula inside H2s or supporting paragraphs, you help both humans and crawlers understand what entity the page represents.

Execution matters as much as the math. Follow the built-in procedure: Step 1: Enter the nominal annual rate as a percentage. Step 2: Set the number of compounding periods per year. Step 3: Review the effective annual rate, periodic rate, and monthly equivalent.. Each numbered instruction is short enough to scan on mobile but descriptive enough to satisfy Google’s Helpful Content guidelines. Encourage students to jot down units, double-check signs, and compare answers with the Example card to build confidence.

The Example section itself is packed with semantic clues: “Nominal rate = 8%, Compounding = Quarterly (m = 4)” leading to “EAR ≈ 8.24%, Periodic rate = 2.00%, Monthly equivalent ≈ 0.64%.” Pepper similar narratives throughout your copy (and internal links from related guides) so canonical search intents are answered without pogo-sticking back to Google.
