It's just basic math, really.

-- The current amount of experience 
local current_exp = 3000 
-- The next level's experience 
local next_exp = 4000 
-- Calculate the percentage till next level 
local percentage = math.ceil( 100 - ( current_exp / next_exp * 100 ) ) 
print( percentage ) -- Prints 25 

Note, that you should extend the mathematical algorithm further, as at the moment you are not able to calculate more than one level with this code (it will start from 50 percent from level 2 on).

I do not understand

[myonlake]

Use the mathematical algorithm inside the print function, for example like the following:

-- The current amount of experience the player has 
local current_experience = 0 
  
-- Ascending order with numerical keys containing the experience points for each level 
local experience_levels = { 
    100, 250, 500, 1000, 1500, 2000, 2750, 3250, 4000, 5000, 6250, 7500, 8750, 10000 
} 
  
-- A function to get the level from experience points 
local function getLevelFromExperience( experience ) 
    if ( type( experience ) ~= "number" ) then return false, 1 end 
    -- Loop through all experience levels 
    for level,_experience in ipairs( experience_levels ) do 
        -- If there is another level after the current level 
        if ( experience_levels[ level + 1 ] ) then 
            -- If the current experience is less than the next level's experience 
            if ( experience < experience_levels[ level + 1 ] ) then 
                -- Return this level 
                return level 
            end 
        else 
            -- If no other level was found, then return the current level 
            return level 
        end 
    end 
    return false, 2 
end 
  
-- A function to calculate and return the percentage to next level 
local function getPercentageToNextLevel( experience ) 
    if ( type( experience ) ~= "number" ) then return false, 1 end 
    -- Check if the current experience doesn't exceed the maximum experience points 
    if ( experience ~= experience_levels[ #experience_levels ] ) then 
        -- Get the current level 
        local level = getLevelFromExperience( experience ) or 1 
        -- Get the amount of experience required till next level 
        local experience_to_level = experience - experience_levels[ level ] 
        -- Reset the next level experience properly 
        local fixed_experience = experience_levels[ level + 1 ] - experience_levels[ level ] 
        -- Calculate and return the percentage between the levels 
        return math.ceil( 100 - ( experience_to_level / fixed_experience * 100 ) ) 
    end 
    return 0 
end 
  
-- Get the current width and height of the screen 
local screen_width, screen_height = guiGetScreenSize( ) 
  
-- Initialize a renderer to draw the level data on screen 
addEventHandler( "onClientRender", resourceRoot, 
    function( ) 
        -- Get the current level 
        local level = getLevelFromExperience( current_experience ) or 1 
         
        -- If the experience is less than the maximum amount, then increment the current experience for demonstration 
        if ( current_experience ~= experience_levels[ #experience_levels ] ) then 
            current_experience = current_experience + 2 * level 
        end 
         
        -- Initialize a string containing the data 
        local text = "Current level: " .. level .. " | Current experience: " .. current_experience .. " (Progress till next level: " .. getPercentageToNextLevel( current_experience ) .. "%)" 
  
        -- Draw a shadow under the actual text 
        dxDrawText( text, screen_width - dxGetTextWidth( text, 2.0 ) - 14, screen_height - dxGetFontHeight( 2.0 ) - 14, screen_width, screen_height, tocolor( 0, 0, 0, 125 ), 2.0, "default", "left", "top" ) 
        -- Draw the actual text containing the level data 
        dxDrawText( text, screen_width - dxGetTextWidth( text, 2.0 ) - 15, screen_height - dxGetFontHeight( 2.0 ) - 15, screen_width, screen_height, tocolor( 255, 255, 255, 225 ), 2.0, "default", "left", "top" ) 
    end 
) 

Note that the code is client-side as it has a renderer, but you can use the rest of the code server-side as there are no limitations there. I have not tested the text rendering however as I cannot try it right now, but the math and everything works as I tried it on the Lua engine.

I also extended the mathematical algorithm so, that there is no issues with the levels no longer.
