Quick answer
A good swim time depends on age, gender, event, and pool (SCY, SCM, or LCM). The most useful benchmark is official age-group time standards (B, BB, A, AA), not a teammate's time. A 10-year-old girl going 39.89 in the 50 Free SCY is at the USA Swimming B cut. The same time at 14 is slower than B. Use the tables below, then sign in to Gophin (free) to see your swimmer's exact gap.
Rafa's first 50 Free was somewhere around 45 seconds. "Is that good for her age?" I asked her coach after the meet. He smiled and said, "It's a starting point." Two years later, she is in the low 28s. Context is everything, and I wish someone had explained that to me on day one.
It is one of the most searched questions by swim parents, and one of the hardest to answer honestly: is my child's swim time good?
Maybe your ten-year-old just swam a 38-second 50 freestyle and you have no idea if that is fast, average, or behind. Maybe another parent casually mentioned their kid's time and now you are quietly spiraling. Maybe you just want to understand where your swimmer stands so you can set reasonable expectations.
All of those feelings are valid. But the real answer is more nuanced than a single number on a chart.
Why "Good" Is Relative
The first thing to understand is that there is no universal definition of a "good" swim time. A time that earns a ribbon at a local developmental meet might not qualify for a regional championship. A time that seems slow at age eleven might be exceptional for a swimmer who only started competing six months ago.
Context matters enormously. A swim time cannot be evaluated in isolation -- it depends on age, gender, stroke, distance, course type (short course or long course), and how long the swimmer has been training. A 35-second 50 freestyle means something completely different for a nine-year-old girl in a 25-yard pool than it does for a fourteen-year-old boy in a 50-meter pool.
This is why raw comparisons between swimmers rarely tell you anything useful.
Age Group Standards: The Real Benchmarks
The most reliable way to evaluate a swim time is through age group standards. Organizations like Swimming Canada and USA Swimming publish time standards that categorize performances into tiers. These tiers give swimmers concrete goals and help parents understand where a time falls within the broader competitive landscape.
USA Swimming motivational times (the tables below) run B, BB, A, AA, AAA, AAAA. B is the entry competitive mark. AA is a strong regional swimmer.
Canada is not that same letter ladder. The national pathway is usually club and regional meets, then each province's championship cuts, then Eastern or Western, then Nationals and Trials. Some Canadian clubs still say "B time" as a local label. For the real cuts, use our Swimming Canada standards guide.
The concept is the same everywhere: a published cut gives a time meaning beyond a number on one Saturday.
How Times Vary by Age, Gender, Stroke, and Course
It is critical to compare apples to apples. Here is why:
Age: A twelve-year-old and a fourteen-year-old are in dramatically different stages of physical development. A large-scale PMC study of backstroke times (nearly 10,000 swimming years) found that performance improves by 9-10% per year at ages 8-10, slows to about 5% per year at ages 11-14, and drops to just 1-2% per year by ages 15-18. That is one stroke, not a law for every event. Puberty changes everything -- muscle mass, limb length, lung capacity, power output. A time that is average for a twelve-year-old might be below average for a fourteen-year-old, and that is completely normal.
Gender: Boys and girls develop on different timelines. In the younger age groups, girls often outpace boys. The same study found that females typically plateau around age 14, while males plateau around age 16. Around puberty, boys typically see larger time drops due to increases in muscle mass and upper body strength. Standards reflect these differences, with separate time benchmarks for each gender.
Stroke: A "good" time in backstroke is different from a "good" time in breaststroke, butterfly, or freestyle. Each stroke has its own biomechanics, energy demands, and speed profiles. Freestyle is the fastest stroke; butterfly requires the most energy per meter; breaststroke is the slowest but most technically demanding.
Course type: Short course (25-yard or 25-meter pools) produces faster times than long course (50-meter pools) because swimmers benefit from more walls, more turns, and more push-offs. A 1:10 in short course yards is not the same as a 1:10 in long course meters. Always compare times within the same course type. For converting a yards time to meters, use the swimming time converter.
50 Free Times by Age (USA Swimming Motivational)
These are official USA Swimming single-age motivational cuts, not recreational averages. B is the entry competitive mark. AA is a strong regional swimmer. Times are season-best targets, published by USA Swimming. Faster than B is good for a developing club swimmer. Faster than A is a solid age-group result. Missing B does not mean your child is behind. It means they have a clear next mark.
How to read the table: find your swimmer's age and gender. Compare their 50 Free to B, then BB, A, and AA. Always match the course. SCY is a 25-yard pool (most US winter meets). LCM is a 50-meter pool (summer championships).

100 Free Times by Age (SCY)
The 100 Free is the event most parents look up after a 50. Same rules: match age, gender, and course. A 1:11.49 100 Free SCY is the A cut for a 10-year-old girl and slower than B for a 14-year-old girl.
100 Free SCY, girls
| Age | B | BB | A | AA |
|---|---|---|---|---|
| 10 | 1:30.89 | 1:21.19 | 1:11.49 | 1:08.29 |

| 14 | 1:05.09 | 1:00.39 | 55.79 | 53.49 |
Long course (LCM) cuts are slower because there are fewer turns. A 10-year-old girl's 50 Free B is 39.89 SCY and 45.39 LCM. For the full B through AAAA ladder, including 11-12 and 13-14 age groups, see swimming standards by age and the USA Swimming time standards guide.
Motivational vs. Qualifying Standards
Not all standards serve the same purpose. Some are designed to motivate -- they give developing swimmers achievable goals that celebrate progress. Others are qualifying cutoffs that determine who can enter specific meets.
Understanding this distinction matters. If your ten-year-old just hit a motivational time standard, that is worth celebrating. It does not mean they are "behind" because they have not hit a qualifying standard yet. The standards exist on a spectrum, and every tier represents real achievement.
Percentile Rankings: A Better Way to Understand Position
Beyond standards, percentile rankings provide another useful lens. A percentile tells you what proportion of swimmers in the same age group and event your child's time is faster than. For example, if your swimmer is in the 75th percentile for the 100 backstroke in the 11-12 age group, their time is faster than 75% of swimmers in that category.
Percentiles are helpful because they account for the full distribution of times, not just the elite cutoffs. They answer the question parents actually want to know: where does my child's time fall relative to peers?
However, percentiles still carry a risk. It is easy to become fixated on climbing from the 60th to the 70th percentile and lose sight of the fact that your swimmer improved by two seconds in three months -- which might be a remarkable achievement regardless of percentile movement.
Why Comparing to Others Can Mislead
The temptation to compare your swimmer's times to their teammates or competitors is powerful. But comparisons often mislead for reasons you might not expect:
- Training history varies. A swimmer who has trained year-round for four years has a very different baseline than one who started eighteen months ago.
- Growth timelines differ. The early developer who towers over their age group may dominate at twelve and plateau at fifteen. The late bloomer may seem behind and then rocket up the rankings after a growth spurt. USA Swimming's 2024 demographic data shows that membership retention is just 66.9%, with the sharpest dropout at age 13 for girls and age 17 for boys -- often the very ages when late bloomers are about to break through.
- Event specialization matters. Some swimmers are sprinters, others are distance swimmers. Comparing a natural distance swimmer's 50 free to a natural sprinter's is like comparing a marathoner's 100-meter dash to a track sprinter's.
- Motivation and goals differ. Not every swimmer is chasing nationals. Some are in it for fitness, for friends, for the love of the water. Their times are not "worse" -- they are pursuing different things.
The only comparison that truly matters is your swimmer versus their own past performances. That is where you see real growth.
How Gophin Puts Times in Context
This is exactly the problem Gophin was built to solve. Instead of searching through spreadsheets, results databases, and standard tables scattered across multiple websites, Gophin aggregates your swimmer's official competition results and maps them against recognized standards, all in one place. Gophin is free for everyone. You do need to sign in so the times attach to your swimmer.
Sign in free and see your swimmer's gap to B, A, or AA
With Gophin, you can:
- See your swimmer's best times pulled automatically from official competition records -- no manual entry needed.
- View evolution charts that show time improvements over weeks, months, and seasons -- so you can see progress even when the numbers change by fractions of a second.
- Understand meet results in context, with times organized by event, course, and date.
- Compare against 38+ standards organizations to see exactly where your swimmer stands and which qualifying times are within reach.
Instead of guessing whether a time is "good," you get a clear, data-driven picture of where your swimmer stands and how they are improving.
The Real Answer
So, is your child's swim time good?
If they are working hard, showing up to practice, competing with courage, and improving over time -- yes. Their time is good. Standards and percentiles are useful tools for setting goals and tracking progress, but they should never be the sole measure of a young swimmer's worth.
The best way to answer the question is not to look at a single number. It is to look at the trajectory. Where were they six months ago? What have they achieved since? What are they working toward?
That trajectory -- the steady, sometimes frustrating, always meaningful arc of improvement -- is what makes a swim time good.
