Katie Holmes will receive US$3 million ($NZ3.74m) for every year she was married to Tom Cruise.
The 33-year-old actress has filed for divorce from the 49-year-old actor - who she wed in November 2006 - and as she had signed a pre-nuptial agreement before they tied the knot, she is unable to seek half his rumoured $275 million fortune.
Instead, she will reportedly be paid $15 million for the five-year union as well as being given their $35 million Beverly Hills mansion.
However, Katie - who has cited "irreconcilable differences" as the reason behind their split - is seeking sole custody of the couple's six-year-old daughter, Suri, and experts believe she will get a huge amount of child support from Tom.
Top divorce attorney Vikki Ziegler told Hollywoodlife.com: "Most of the estate is Tom's. She'll have to go for a lot of child support. She'll have to show that Suri has nannies, cars, activities, clothes, hair appointments. That a hefty amount each month is needed to maintain Suri's lifestyle."
