Full-time, part-time, and live-in nanny rates
| Arrangement | Typical hours | Average rate | |
|---|---|---|---|
| Full-time | 35–50 hrs/week | $26.89/hr | See full-time rates → |
| Part-time | 10–25 hrs/week | $25.01/hr | See part-time rates → |
| Live-in | Set by family | $26.89/hr | See live-in rates → |
Part-time runs slightly lower per hour than full-time here, which often means strong full-time demand supports higher rates for committed schedules.
Live-in rates here run higher than live-out — uncommon, but typically reflects specialty demand for around-the-clock or live-in newborn care. The trade-off is space — you'll need a private bedroom and ideally a separate bathroom for the nanny.

Tips to find a great nanny without overpaying
- Be flexible on experience. Some of the best nannies on the platform have 3–5 years on the job and charge meaningfully less than experienced nannies with 10+ years. References matter more than years.
- Consider a share. If your kids are similar ages and you live near another family, a share is the single biggest cost reduction available without compromising on care.
- Be specific about hours upfront. Most nannies will take a slightly lower rate for a guaranteed steady schedule than for a higher-rate, unpredictable one.
- Bundle benefits thoughtfully. Two weeks PTO, a health stipend, transit passes, education assistance, or an annual raise commitment can help close the gap with families offering a higher hourly rate.
- Match rate to responsibilities. A higher rate often makes sense once you add cooking, errands, or driving. Don't compare apples to oranges across listings.

To keep it going!!! I’ve had many experiences throughout the four years , all which have been amazing. I have dealt with all sorts of different ages starting from infants to 11 years old, I am certified in CPR and have degree is criminal justice and now continuing my major for law school. I will strictly enforce the rules you have for your child but still manage to make sure a fun, safe, and gentle environment is in place. i incorporate crafts into their daily activities as well as making sure they get a lot of outside play. I am also available for lighthouse cleanings, and simple meals. Thank you!
