Zelenskiy's government said in May it would study possible measures to boost military personnel numbers after talks on how to end the war with Russia stalled.
"We agreed on how to increase the financial resilience of our defence and further transformation of the Ukrainian army," Zelenskiy said in his daily address after meeting key cabinet ministers.
"The cabinet of ministers will approve a specific mechanism, and the government should start the first new payments as early as June," he added.
Ukraine has secured a 90 billion euro ($A148 billion) loan from the European Union, allowing the government to increase defence spending to a record 4.4 trillion hryvnias ($A138 billion) this year.
The funds are due to start flowing this month.
Zelenskiy said on Friday the government would raise the basic military wage by one-third to $A995.
The step was aimed at matching the country's average monthly salary, which has steadily risen during the war due to staff shortages, military analysts and economists said.
Infantry soldiers fighting on the frontline will receive an average monthly salary of $A9950.
They will also be offered a new type of fixed-term contract for 10, 14, or 24 months for combat duties.
Ukraine also wants to recruit more foreign fighters.
"I have instructed to create significantly more opportunities to recruit foreign volunteers into the Ukrainian army, and there will be more recruitment channels in this regard," Zelenskiy said.
About 10,000 foreign volunteers have joined the Ukrainian army from more than 70 countries since the war began, according to estimates by Ukrainian military publications.
Russia has more than 700,000 troops deployed in the war zone in Ukraine, Russian President Vladimir Putin said on Friday while conversing with soldiers at the Kremlin.
Flanked by Defence Minister Andrei Belousov, Putin spoke confidently of victory in the "special military operation" he ordered against Ukraine in February 2022.
"Step by step, not as quickly as we would like, but we are moving forward nonetheless; We are moving forward every day," Putin said.
As early as December, during his annual press conference and public Q&A session, he had spoken of about 700,000 soldiers in Ukraine.
At the time, he said they were mainly young people, including those born in the 1990s.
The soldiers spoke at length about problems caused by drones deployed by the Ukrainian military, which also uses the Starlink satellite communications network for this purpose.
Russia lost access to this network earlier this year.
Putin acknowledged that Ukraine had stepped up its use of drones to divide Russian society and inflict economic damage but insisted that this has not worked.
Russia is now developing drones equipped with artificial intelligence and building its own network of low-earth orbit satellites, he added.
Technically, the problem had been solved and it was just a matter of scaling up, according to the president.
For months, the Ukrainian military has been intensifying its drone strikes on Russia's oil industry to deprive the war effort of fuel, decrease earnings from exports and erode public support for the war.
