Why APY matters for your business

You’re already working hard to bring money into your business. APY helps that money keep working for you—even on nights, weekends, and slow seasons.

APY (Annual Percentage Yield) reflects how much interest you’ll actually earn over a year, factoring in compounding. That means you're earning interest on your interest, not just on your starting balance.

Why it matters for your business:

Put your money to work

A high APY means your balance earns, whether or not you’re making monthly deposits.

See the full picture

Unlike flat interest rates, APY includes compounding, so your earnings grow exponentially.

Make smarter money moves

APY helps you compare accounts based on actual earnings, not just advertised rates.

Stop leaving money on the table

If you're already holding cash for taxes, payroll, or operating costs, APY helps you get more from what’s just sitting there.

What is APY and how is it calculated?

APY (Annual Percentage Yield) shows the total amount of interest your account earns over a year, including the impact of compounding. Think of it as your return-on-balance. It’s the clearest way to see what your money can earn—interest on interest, without you lifting a finger.

At North One, interest is compounded monthly and calculated using your average daily balance—so the more consistent your balance, the more you can earn.

Here’s the formula behind it:

Where:
i = interest rate
n = number of compounding periods per year

No need to crunch the numbers yourself, our calculator does the math for you instantly.
