> The natural rate of unemployment calculator works out the natural rate – frictional plus structural unemployment – and the cyclical unemployment that remains, from the numbers of unemployed of each type and the labor force.

## Inputs

- Frictionally unemployed
- Structurally unemployed
- Cyclically unemployed
- Labor force

## Results

- Natural rate of unemployment
- Actual unemployment rate
- Cyclical unemployment rate

## Formula

```
Natural rate = (frictional + structural unemployed) ÷ labor force × 100
Cyclical unemployment = actual rate − natural rate
```

## Explanation

Even in a healthy economy some unemployment exists as people change jobs (frictional) or skills don't match jobs (structural). The CBO estimates the U.S. natural rate at roughly 4–4.5%.

### How to use the Natural Rate of Unemployment Calculator

- **Frictionally unemployed**
- **Structurally unemployed**
- **Cyclically unemployed**
- **Labor force**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the frictional, structural and cyclical unemployed and the labor force.

### Tips

- Use real (inflation-adjusted) figures to compare across years.
- Check whether data are seasonally adjusted.
- Use the same currency and base year throughout.
- Economic models simplify reality – treat results as illustrations, not forecasts.

### Common mistakes to avoid

- Mixing nominal and real values.
- Comparing percentage changes with percentage-point changes.
- Treating correlations as causes.

### What each result means

- **Natural rate of unemployment** = ([Frictionally unemployed] + [Structurally unemployed])÷[Labor force]×100
- **Actual unemployment rate** = ([Frictionally unemployed] + [Structurally unemployed] + [Cyclically unemployed])÷[Labor force]×100
- **Cyclical unemployment rate** = [Cyclically unemployed]÷[Labor force]×100

### Example values

How the main result changes when **Frictionally unemployed** changes and everything else stays at the example values above:

## Worked example

Inputs — Frictionally unemployed: 3,000,000; Structurally unemployed: 3,500,000; Cyclically unemployed: 700,000; Labor force: 170,000,000.

Results — **Natural rate of unemployment = 3.82 %**; Actual unemployment rate = 4.24 %; Cyclical unemployment rate = 0.41 %.

## FAQ

**What is the natural rate of unemployment?**
Unemployment when the economy is at full employment – frictional plus structural.

**Is the natural rate zero?**
No – some job searching and skill mismatch is always present.

**Can the natural rate change?**
Yes, with demographics, policies and technology.

**What formula does the Natural Rate of Unemployment Calculator use?**
Natural rate = (frictional + structural unemployed) ÷ labor force × 100.
