No official figure for Michael Greller’s net worth has ever been confirmed. This article breaks down exactly how that estimate is built, using Spieth’s real career earnings rather than a guess.

Michael Greller Net Worth in 2026: Where the Number Really Stands
Search results for Michael Greller net worth turn up wildly different numbers. Some pages say $5 million. Others claim $10 million or more. A few go even higher.
None of these sites show their work. Several appear to repeat the same unverified figure without checking where it came from.
The $5 million number traces back to a report from around 2018. That was back when Spieth’s career earnings were far lower than they are today.
The $10 million figure is the most common one still circulating, and it likely factors in investment growth on top of straight caddie income. Maria Fassi published figures have the same problem in reverse, where a round $1.5 million guess keeps circulating long after her actual earnings stopped moving.
Based on a bottom up calculation using Spieth’s actual career money, a realistic range for 2026 is $5 million to $10 million. The $7 million to $8 million band stands out as the most defensible single estimate.
Michael Greller Career Earnings: What 13 Years on Spieth’s Bag Have Paid
Jordan Spieth’s official PGA Tour career earnings total roughly $96.8 million as of October 2026. That includes $81.87 million in regular Tour money and $14.97 million from major championships, according to Spotrac.
This single number matters more than any other. A caddie’s pay is tied directly to his player’s prize money.
Using a blended rate of about 7 percent, his tournament based income works out to roughly $6.8 million. Add weekly base pay across 14 seasons on tour, and his gross lifetime caddie income lands somewhere between $7.5 million and $8 million before taxes and expenses.
Caddies cover their own travel and lodging, which usually runs $25,000 to $50,000 a year. Over 14 seasons, that likely removed close to half a million dollars from the total. Rico Abreu faces the same deduction on a bigger scale, where a sprint car team’s running costs come out of every purse before anything reaches the driver.
After self employment taxes, Greller’s net accumulated income from caddying alone is estimated at $4.5 million to $6.5 million. That figure sits comfortably within the lower end of the commonly cited net worth range.
The Math Teacher Who Volunteered His Way Onto Spieth’s Bag
Before he carried a Tour bag, Greller spent his days in a classroom. He taught math and science to sixth graders at Narrows View Intermediate School near Seattle, earning around $77,000 a year.
That was a solid wage for a school teacher. It was nowhere close to Tour money.
His path toward professional golf began in 2006, when he volunteered to caddie for free at a local amateur event. That favor eventually connected him to Justin Thomas. Thomas gave him a crucial recommendation ahead of the 2011 U.S. Junior Amateur, pairing him with a teenage Jordan Spieth. Spieth won that week.
The two joined up again the following year at the U.S. Open, where Spieth played as the low amateur.
When Spieth turned pro in December 2012, he asked Greller to come along full time. Greller originally planned on taking just one season away from teaching.
Spieth’s rapid rise changed that plan. That single season turned into a career. The two became one of the most recognized duos in the sport, built on quick on-course trust as much as results.
How Spieth Pays Greller: The Weekly Fee and the 5/7/10 Cut
PGA Tour caddies work as independent contractors, not employees. Most operate under a pay structure commonly called 10-7-5.
A caddie earns 10 percent of winnings for a tournament victory, 7 percent for a top-10 finish, and 5 percent just for making the cut. On top of that, players usually pay a weekly base fee, generally between $1,500 and $3,000, whether their golfer makes the cut or not.
Spieth and Greller have never disclosed the private details of their own arrangement. Given how long they have worked together, and how much Spieth has earned, it is fair to assume Greller sits near the top of this pay scale.
2015: The Season Greller Out-Earned Tiger Woods
The 2015 season remains the high point of Greller’s career. Spieth won both the Masters and the U.S. Open that year, becoming a three time major champion two years later after the 2017 Open Championship.
Press reports at the time put Greller’s bonus from the U.S. Open alone at around $180,000.
During one especially hot stretch in April 2015, Spieth won the Masters title and finished runner up twice within about a month. Business Insider estimated Greller pocketed close to $375,000 in bonuses during that single stretch. That was worth more than four times what he used to earn in a full year as a teacher.
Across the full 2015 season, Spieth’s prize money reached about $22 million. That means Greller’s share from that one year alone came in around $2.1 million, enough to place him ahead of more than 200 Tour players including Tiger Woods and Phil Mickelson.
Four-Plus Years Without a Win: What Spieth’s Slump Costs Greller
Spieth’s last PGA Tour victory came at the 2022 RBC Heritage. Since then, injuries have slowed him down significantly.
A wrist problem that had bothered him for years finally required surgery in August 2024, wiping out the back half of that season. Spieth returned for 2025 and played through 2026, but a win has stayed out of reach.
His best result of the 2026 season came at the Masters, where a tie for twelfth place paid $427,500. Without wins, Greller’s bonus income naturally drifts closer to the 5 to 7 percent range instead of the full 10 percent a victory brings.
There was brief talk in 2025 that Spieth might change caddies. Greller even filled in for Max Homa in January 2025, at The Sentry, while Spieth was still sidelined after his wrist surgery. It was a one-week gig before Homa’s regular caddie returned.
By early 2025, Greller was back on Spieth’s bag for good. The duo remains together heading into the rest of the 2026 season.
Where Greller Ranks Among Golf’s Richest Caddies
Greller is well paid, but he is not the richest name in the caddie field. A few comparisons offer useful context.
Steve Williams, the All-Time Benchmark
Steve Williams caddied for Tiger Woods from 1999 to 2011 and is widely seen as the benchmark for caddie earnings. He reportedly collected around $12 million from his share of Woods’ prize money during those years. His net assets today are estimated near $20 million.
Ted Scott and the Scheffler Windfall
Ted Scott, who caddies for Scottie Scheffler, had a standout 2026 season. Based on a standard 10-7-5 split applied to Scheffler’s prize money, Scott’s share for the year works out to roughly $5.88 million.
Harry Diamond: What McIlroy’s Caddie Earns
Harry Diamond has caddied for Rory McIlroy since 2017. Two wins in the first quarter of 2025 alone may have earned him close to $900,000 in bonuses. Given McIlroy’s consistent play, Diamond’s annual bonus income has likely reached seven figures in several recent seasons.
Lance Bennett: What Tiger Woods Pays His Caddie
Tiger Woods’ current caddie is Lance Bennett, who joined him at the 2024 Genesis Invitational after Joe LaCava left to work full time for Patrick Cantlay. The exact terms of Bennett’s deal have never been made public. Woods has reportedly paid his caddies 10 percent of winnings regardless of where they finish.
Ellie Greller, Chambers Bay and Life Off the Tour
Away from the golf course, Greller is married to his wife, Ellie. The couple is reported to have exchanged vows at Chambers Bay, the Washington golf course closely tied to Greller’s own roots as a local caddie.
Specific details about their family life have not been made public. Greller tends to keep that part of his life private, away from press and cameras.
The Bottom Line on Greller’s Fortune
Michael Greller’s net worth most likely falls between $5 million and $10 million. The $7 million to $8 million band stands out as the most defensible estimate.
That fortune was built almost entirely on one number: a steady percentage of Jordan Spieth’s prize money, dollar for dollar, season after season. The biggest factor in whether that number keeps climbing is simple. If Spieth starts winning again, Greller’s share grows right along with him.
