TLDR
- Extra or per diem shifts are the most common way nurses earn more, but they are more hours of the same job, at a rate the employer sets.
- Side hustles that sell nursing knowledge directly include teaching certification courses such as CPR and first aid, private care arrangements, health education for workplaces, tutoring nursing students, and consulting work that draws on clinical experience.
- These let you set the rate and can grow beyond one-to-one hours, for example by teaching groups.
- Before starting, check your employer’s rules on outside work, your licence and scope of practice, and whether you need your own insurance.
Ask nurses how they earn more and most will say the same thing: pick up shifts. It works. It’s also the one option that can’t grow, because it’s the same job with fewer days off.
More shifts versus selling your skill
| Option | Who sets the rate | Can it grow past your hours? |
|---|---|---|
| Extra or per diem shifts | The employer or agency | No |
| Teaching CPR, first aid or certification courses | You, within the course provider’s terms | Yes, classes are groups |
| Tutoring nursing students | You | Yes, with groups and exam prep |
| Health education for workplaces or community groups | You | Yes, one session reaches many people |
| Private care arrangements | You and the family | Partly, still one client at a time |
| Consulting that draws on clinical experience | Negotiated | Partly, project work |
The common thread in the useful ones: someone pays for what you know, and you can teach or advise more than one person at a time.
A shift sells your hours. Teaching sells your knowledge to a room.
What it does to your money
Two group classes a month with ten people each, at $50 a person as an example price, is $1,000 a month for a few hours of teaching. Saved and invested at 5% a year after inflation, an extra $1,000 a month takes roughly seven and a half years off a typical 30-year path to financial independence. The maths is here.
Earning the same $1,000 from extra shifts usually costs more of your time, and it stops the week you stop working them.
Where this comes from
I’m an occupational therapist, not a nurse, but the pattern is the same across healthcare. My first salary was $1,700 a month. Selling the same clinical skill directly took my first month to $4,800, because the hospital had been keeping most of the value I produced. The full story is here. Healthcare skills are some of the most undersold in any workforce.
Before you start
- Check your employer’s rules. Some contracts restrict outside clinical work or require approval.
- Stay inside your scope of practice and licence. What you can do independently varies by country and registration.
- Sort out insurance. Your employer’s cover usually doesn’t extend to work you do on your own.
- Start with teaching. It’s usually the lowest-risk way to sell nursing knowledge, and it can grow.
Run your own
Open the calculator and pick “I don’t have a business yet”. Set what you’d build to $1,000 a month, then $3,000, and compare the dates. The six levels of a service business shows where a skill like nursing can go after the first paying client.
