Much like at restaurants and hair salons, the industry standard for tipping at the nail salon ranges around 15 to 20 percent, and it is generally recommended that if you've received extra services or specialty designs, a minimum of 20 percent is appreciated.

"For example, if your service costs $50, you should see it as costing $60." The widely accepted minimum tip in the industry is 15 percent, Kandalec says, but the most common tip at a nail salon is 20 percent. This is similar to what's expected when tipping at a hair salon, or for a massage or spa treatment.

For instance, how much do you tip for a $50 pedicure? Depending on your satisfaction, $7.50 is a standard tip, $10 is a good tip, and if your nail tech really went the extra mile, $13 is a great tip.

If the total for your manicure was $50, tipping $10 is a good tip since it's 20% of the total.
