The cost of surrogacy varies on a case-by-case basis. Each case is unique and may require additional treatments or more time for the treatment to be successful. In any case, the average cost of surrogacy ranges from $90,000 to $115,000. Again, it should be clear that it depends on the situation of each intended parent. This estimation might be higher if done in California, where the high demand for surrogates increases the overall cost.
