The company hopes the aircraft will be cleared to fly again in the Autumn following two crashes in which hundreds died.
Boeing is taking a $4.9bn (£3.9bn) charge to compensate airlines following the prolonged grounding of the 737 MAX fleet after two crashes.
The crisis-hit firm said lost sales, reduced production and the compensation payments it was expecting to hand over to date would cost it $6.6bn (£5.3bn).
The sum does not include any provision for lawsuits expected to be filed by the families of those killed.
The world's biggest plane-maker said the bill would be reflected in its second quarter results in the form of a $5.6bn (£4.5bn) reduction in revenue and pre-tax profit.
All 737 MAX planes have been banned from flying since March after crashes in Ethiopia and Indonesia that together killed 346 people in a space of five months.
Boeing Chief Executive Dennis Muilenburg tweeted that the company remained focused on safely returning the 737 MAX to service.
"The MAX grounding presents significant challenges for our customers, company and supply chain," he tweeted.
Boeing said it assumes the 737 MAX will return to service in the US and other countries in the Autumn but could not give an exact date.
Such a development would need the approval of world aviation regulators.
Ryanair is among the airlines expected to claim compensation from Boeing.
The airline said on Tuesday that it had been forced to cut future services because of uncertainty over the timing of deliveries of 737 MAX planes.
Boeing shareholders took the announcements in their stride, with the stock rising 2% in after-hours trading in New York.
The 737 MAX began flying passengers in 2017 and is Boeing's best selling aircraft. Despite this, less than 400 have been delivered to airlines.
In October 2018, a MAX aircraft operated by Indonesia's Lion Air crashed, killing all 189 people on board.
A second crash happened in March this year in Ethiopia, killing 157 people, forcing regulators around the world to ground the plane.
A problem with the aircraft's flight control software was identified as the cause, but last month Boeing said further software problems had been found requiring further work.
