Percentage? What are you talking about?
There is 100% chance of getting an Egg as long as the old man doesn't say "They prefer to play with other Pokemon". It will just take longer.
There is a percentage involved, and it's not 100%.
When you place two pokémon in the daycare, and they can mate, a number is created. The number depends on how much the two pokémon like eachother (The more they like eachother, the higher the number), but it's always between 100 or 200 (I might not get these numbers straight, it's been a long time since I read this). Now, after a certain amount of steps, another random number is created. Now, to get an egg, the 2nd random number should be UNDER the first random number. So, let's say the "love"-value is 180 (pretty high), and a random number is generated (150) the pokémon will get an egg. But, if the two pokémon didn't like eachother as much, and the love-value would be 120, they wouldn't get an egg. So the chance (as a percentage) can be calculated knowing this.
I think the place I read it is down now, so I can't confirm it, but it was somewhat like this.
