Nominal vs. Real vs. Effective Interest Rates
Interest rates, made clear.
Understanding how interest is presented matters. These three rates describe different views of cost and return — and knowing the difference helps you make better decisions for your practice.
Not all rates mean the same thing.
When you lease equipment through Clear Capital, you are not just spreading out a cost. You are making a strategic decision about how your business uses capital — keeping your resources available for the things that actually drive growth.

RATE 01
Nominal rate
The stated rateThe stated or advertised rate on a lease or loan. It does not account for compounding or inflation — it is simply the base rate used for quoting and pricing.
Example: A 9% lease rate quoted in a contract is the nominal rate.
- No compounding
- No inflation
- Used for pricing
RATE 02
Real rate
Adjusted for inflationThe true economic return after inflation is taken into account. Most relevant when evaluating longer-term capital decisions where purchasing power matters.
Example: 9% rate minus 3% inflation = approximately 6% real rate.
- Includes inflation
- Long-term planning
RATE 03
Effective rate
The true annual costThe true annual cost once compounding is factored in. The most accurate way to compare financing options on an apples-to-apples basis.
Example: 9% nominal compounded monthly produces an effective rate slightly above 9%.
- Includes compounding
- Best for comparison
The real rate formula
A simple way to calculate the real interest rate is to subtract the inflation rate from the nominal rate.
Formula: Real Rate = Nominal Rate − Inflation Rate (approximate)
