Quick answer
Spray tans average ~$45 a session (about $1,600+ a year if you tan year-round), while at-home self-tanner runs roughly $200–$400 a year - saving well over $1,000. The trade-off: a spray tan usually lasts a few days longer per application.
The 30-second answer
Per application, a salon spray tan costs about $45 plus tip while a $30 bottle of self-tanner covers 6–8 applications - roughly $4 each. According to a 2026 survey of 239 US salons, the average spray tan is $44.91. Self-tanner fades a little faster (3–7 days versus 7–10 for a spray), which is why this calculator lets you set each frequency independently to keep the comparison honest.
How much does a spray tan cost in 2026?
The US average is about $45 a session, but the format matters: a walk-in booth runs $30–$55, a hand-applied airbrush is $60–$95, and a mobile artist who comes to you is $60–$110. Add a 15% tip on airbrush and mobile sessions and biweekly visits land around $90–$100 a month. Enter your real session price above to see your own annual figure.
What self-tanner really costs per year
Quality self-tanner mousse runs $20–$40 a bottle (drugstore options dip near $10), and one bottle covers 6–8 full-body applications. At a $30 bottle and seven apps, that is about $4.29 a tan. Even applying weekly all year, the bottles plus a reusable mitt usually total a few hundred dollars - a fraction of a year of salon sprays.
How many bottles you'll actually use
The calculator divides your self-tan sessions by applications per bottle, so if you reapply every 7 days year-round you go through roughly 7–8 bottles. Tanning seasonally (set months per year to 4) cuts that to two or three bottles - and your salon savings shrink to match.
Longevity tradeoff - spray lasts longer per application
Self-tanner is the clear budget winner, but it is not a perfect swap. A professional spray tan typically lasts 7–10 days and fades more evenly, while self-tan usually holds 3–7 days (5–7 for premium formulas). That is why the verdict is rarely “always cheaper” - it is “much cheaper, with slightly more upkeep.”
The annual cost math
The calculator scales each option by how many days a year you actually tan, then compares the totals:
tanDaysActive = monthsPerYear / 12 × 365
salonAnnual = (tanDaysActive / salonFreqDays) × price × (1 + tip%)
costPerSelfApp = bottlePrice / appsPerBottle
selfAnnual = (tanDaysActive / selfFreqDays) × costPerSelfApp + mitt
annualSavings = salonAnnual − selfAnnualExample: tanning every 10 days year-round at $45 plus a 15% tip is about $1,889. Self-tanning every 7 days at ~$4.29 plus a $12 mitt is about $235 - a yearly saving of roughly $1,650.
When a spray tan is worth it
For a wedding, a big event, or whenever you want a guaranteed flawless, even finish, the salon is worth the premium - a pro reaches your back and avoids the streaks that catch out first-time self-tanners. For routine weekly color, self-tanner saves the most money by far.
When self-tanner is NOT worth it
If you only tan a couple of times a year for special occasions, the per-bottle savings barely register and the convenience and finish of a single spray tan can win. Self-tanner pays off when you tan often enough that the per-session gap compounds across the year.
