The short answer: in Victoria, every racehorse has a rating, a number for how good the handicappers think it is. In a handicap, each rating point is worth 0.5kg, so a better-rated horse carries more weight and, in theory, every runner gets an equal chance. Learn how ratings are set and when they move, and a form guide tells you far more.
This guide explains it in plain English, then shows how to use it when you're picking a bet.

Key takeaways
Every horse has a rating. Racing Victoria's handicappers set it and review it after every run.
One rating point is worth 0.5kg. Ten points between two horses means 5kg between them in a handicap.
Winning costs weight. A win usually adds 3 to 7 rating points, or 1.5kg to 3.5kg more in the same grade next time. The exact rise is up to the handicapper.
Losing doesn't automatically cost points. A rating only drops after genuinely poor runs, and only slowly.
The handicapper rates the past. You're betting on the future. Your edge is spotting horses the numbers haven't caught up with yet.
What is handicapping in horse racing?
Picture a running race where the fastest kids have to carry a backpack. The faster they are, the heavier the backpack. Done right, everyone hits the line together.
That's a handicap. Weight slows a horse down, so the handicapper gives the better horses more of it. Jockeys weigh out before the race and weigh in after it. Lead bags in the saddle make up the difference between the jockey's own weight and the horse's allotted weight.
Not every race works this way. Some races give every horse the same weight, or set weights by age and sex only. The handicap races are where ratings matter most, and they make up much of a typical Victorian race meeting.
Step 1: How is a horse's rating set?
Ratings in Victoria are set by Racing Victoria's handicapping panel. Only their ratings count for Victorian races. Horses coming from interstate or overseas are given a Victorian rating when they're nominated.
A rating is a number on a scale that runs from the 40s up past 120. As a rough guide:
Around 60: a horse in the lower grades, for example a runner in a benchmark 58 or 64 race (written BM58 or BM64, and explained in Step 3).
Around 70 to 80: the middle grades, typical of many provincial and midweek races.
Around 90 and up: good Saturday city handicappers.
105 and up: Group 1 level. An open-age Group 1 winner is rated at least 105.
The handicappers look at the whole of a horse's form, with the most weight on recent runs. For a win, they look at how strong the opposition was, how easily the horse won, the weight it carried, and the margin and time. Every rating is expressed as if the horse were a fully grown four-year-old male. Fillies and mares, and younger horses, get weight allowances on top of that.
You can look up any horse's rating on the Racing Australia website.
Step 2: How do ratings change after a run?
After each start, the handicappers review the run, usually within two to three days. In maiden races, only the winner gets a new rating.
A win: usually 3 to 7 points up (1.5kg to 3.5kg), but the handicapper decides each case. A Saturday city win usually counts for more than a country win, and a dominant win or a big margin can earn extra. Horses already rated 100 or more usually go up only 3 to 4 points.
Second or third: usually 1 to 2 points up.
Unplaced: no automatic drop. Ratings aren't cut just because a horse lost.
A genuinely poor run: may drop 1 to 2 points (0.5kg to 1kg). Bigger drops can follow an injury, a long break or a string of poor runs.
A loss with an excuse: no drop. Wrong distance, wrong track, interference, a slow start or being caught wide aren't reasons to lower a rating.
Notice the imbalance. Ratings go up fast after a win and come down slowly after a loss. That matters a lot when you bet, as you'll see below.
Step 3: How much weight is one rating point?
Most Victorian handicaps are benchmark races, written as BM64, BM78, BM90 and so on. The number is the benchmark rating for that race.
Take a BM90:
A horse rated 90 carries 60kg.
Every point below 90 takes off 0.5kg, so a horse rated 80 carries 55kg.
Weights stop at the 54kg minimum, which is where a horse rated 78 lands. Anything rated lower still carries 54kg.
Every point above 90 adds 0.5kg, so a horse rated 92 carries 61kg. Victorian benchmark races have no upper rating limit, so better horses can run in them. They just carry more weight.
A few extra rules sit on top of that:
Saturday city races: horses below the minimum can run at their true weight, down to 53kg, in Saturday metropolitan (city) handicaps up to BM96. This doesn't apply to Group or Listed races, and a light enough rider must be available. In the BM90 example, a horse rated 77 would carry 53.5kg and anything rated 76 or lower 53kg.
Night meetings: the minimum is 55kg.
Top weight floor: when weights are released, the top weight in most Victorian handicaps must be at least 60kg. If the best horse in the field isn't rated high enough to get that, every horse's weight goes up by the same amount. So in a weak BM70 field, everyone can carry a couple of kilos more than the basic scale says.
What does "on the limit" mean?
This is the bit most punters miss. If a horse's rating would give it less than the minimum weight, it still has to carry the minimum. Racing Victoria calls the weight it should have carried its "true weight".
For example, in a BM90, a horse rated 72 has a true weight of 51kg, but the minimum is 54kg. It carries 3kg more than its rating says it should. In effect, it's competing as if it were rated 78.
On a form guide, you'll often see this described as a horse being "on the limit" or "out of the handicap". It's racing above its class, and the weight tells you so.
How do weights work in the Caulfield Cup and Melbourne Cup?
The big Spring handicaps work the same way, with a few differences. For the Caulfield Cup at Caulfield and the Melbourne Cup at Flemington, the handicapper starts with the top weight and works down to the minimum, which is 51kg (49kg for three-year-olds). The top weight must be at least 59kg.
The other big difference is penalties. Weights for the Cups come out in September, weeks before the races. If a horse then wins a qualifying race in between, the handicapper can add weight to it.
The perfect example is Half Yours in 2025:
When the weights came out, he was on the 51kg limit for both Cups.
He won the Naturalism and picked up a 1.5kg penalty for the Caulfield Cup.
He won the Caulfield Cup, and the handicapper added 2kg for the Melbourne Cup, taking him to 53kg.
He won the Melbourne Cup carrying 53kg.
When the 2026 Melbourne Cup weights came out, he was top weight on 59kg: 6kg more than he carried to win it. The last horse to win the Melbourne Cup carrying 59kg or more was Rain Lover in 1969.
That's handicapping in action. Win, and the weight keeps coming until the horse finds its level. You'll see the same system at work in Group 1 handicaps like the Epsom Handicap.
Which races don't use ratings to set weights?
Weight-for-age (WFA): weights are set by a national scale based on age, sex, distance and the time of year. The Cox Plate is the famous one. There's no handicap, so the best horse usually has the edge.
Set weights: every horse carries the same weight, less 2kg for fillies and mares. The Golden Slipper is one.
Set weights and penalties (SWP): a set weight, plus extra for horses that have won certain races.
Our guide to racing codes and race types covers these in more detail.
How do apprentice claims work?
Apprentice jockeys can claim weight off the horse's allotted weight while they learn:
3kg until they've ridden 20 winners
2kg until 50 winners
1.5kg until 80 winners
In city (metropolitan) races, only city wins count towards those numbers. In provincial races, held at the major regional tracks, city and provincial wins count, and in country races every win counts. Claims aren't allowed in Group or Listed races.
Here's the useful bit: a 3kg claim is worth 6 rating points. The handicappers also ignore the claim when they re-rate the horse afterwards, so a horse that wins with a 3kg claim is rated as if it carried the full weight. Next time, without the claim, it can find things much tougher.
How can handicapping help your betting?
Weight isn't everything. Plenty of horses win under big weights, and there's no official rule that converts kilos into lengths. But understanding the ratings helps you see a race the way the handicapper sees it, and then spot where they might be wrong.
1. Read weight as a change, not a number
60kg on its own tells you very little. What matters is the change. A horse going up 3kg after a win is meeting the same rivals on worse terms. A horse coming down in weight, or dropping into an easier benchmark, is getting a better go.
2. Be careful with last-start winners
A win usually adds 3 to 7 points. If it stays in the same grade, the winner now has to do it again with 1.5kg to 3.5kg more on its back, often against better horses. Last-start winners are popular, so their prices are often short for a horse that's just been made harder to win with.
3. Look for unlucky losers
Ratings don't drop after a loss with a valid excuse. A horse that was held up, caught wide or ran the wrong trip keeps its rating, but its form line looks bad. Punters skim it and move on, so the price can drift. If you've watched the replay and the excuse is real, that's where value hides.
4. Watch for horses slipping down the ratings
Ratings drop slowly, usually 0.5kg to 1kg at a time after genuinely poor runs. After a few of those, a horse that used to be competitive can end up on a much lighter weight in an easier race. If its last runs had reasons (a long break, the wrong track), it could be well placed now.
5. Treat "on the limit" horses with caution
A horse carrying the minimum weight but rated well below it is carrying more than it should. Light weights look attractive on a form guide, but here the horse is actually stepping up in class.
6. Back improvers before the handicapper catches up
Ratings are based on what a horse has already done. Lightly raced horses, three-year-olds, and horses with a new trainer, new gear or a step up in distance can improve faster than their ratings. A horse that keeps winning and keeps rising has to keep improving to cope with the extra weight, and young horses often do.
7. Factor in the claim
A good apprentice with a 3kg claim on a highly weighted horse takes 6 rating points off it. Before you write off a top weight, check who's riding.
8. In WFA races, worry less about the weights
Weight-for-age and set-weight races aren't handicaps. There, focus on class: the highest-rated horse is usually the one to beat.

Frequently asked questions
Who sets the weights in Victorian races?
Racing Victoria's handicapping panel. It gives every horse a rating, reviews it after each run, and handicap weights are worked out from those ratings.
What does BM70 mean?
It's a benchmark 70 handicap. A horse rated 70 carries 60kg, and each rating point above or below moves the weight by 0.5kg, down to the minimum.
Does a horse's rating go down when it loses?
Not automatically. Ratings only drop after genuinely poor runs, usually by 1 to 2 points (0.5kg to 1kg), and not at all if the horse had a valid excuse.
What is a horse's true weight?
It's the weight a horse's rating says it should carry. If that's below the race minimum, the horse carries the minimum instead, so it's effectively racing above its rating.
Why do Melbourne Cup horses get penalties?
Cup weights come out weeks before the race. If a horse wins a qualifying race in the meantime, the handicapper can add weight so it isn't better off than its new form says.
Does an apprentice claim help?
It can. A 3kg claim is worth 6 rating points. Claims aren't allowed in Group or Listed races, and you're trading weight for experience.
