"Pay a price based on spell level"
Note: I use the term "Pay" repeatedly. In this post this simply means to deduct from their starting cash according the published Wealth By Level (WBL) chart.
The chart at the bottom of this answer is the base amount of spells a wizard gets for free. The only answers for "how many additional spells a wizard has learned at upper levels" I've found so far are to charge 150 gp for each spell. Supposedly this is to cover the 100 gp price of the page plus the sell price of the spell in a wizard's spellbook.
This is flawed on its face since it costs 100 gp per page, but each spell takes 1 page per level of the book. So a level 2 spell would cost 200 gp to add to a book. Using the intended logic this would cost 250 gp. So this is the only answer I could come up with.
However, the biggest drawback to this system is that by upper levels the WBL table has them starting with so much coin they could effectively have nearly any spell. (level 15 starts with 200,000 GP) They would have to have additional spellbooks to hold over the 100 page limit but big deal at this point.
The other drawback is that it is ridiculous to assume that anyone has killed this many wizards or convinced that many wizards to share their books. The rulebooks make this sound like a rarity due to how wizards safeguard their research..and the normal charge is 50 gp × spell level (+the cost of writting the spell into their own spellbook). A way around this is to have them pay full price for scrolls. While this solves the "found too many wizard books" problem, it may make the price go too far in the other direction.
Ways to overcome the drawbacks:
- Set an arbitrary number of how many additional spells they could have. I don't like this b/c how do you fairly pick an arbitrary number?
- Set a limit of how many spells they get at the "found spellspook" price (100gp per spell level +50gp) and then allow them to get how many ever scrolls they want. (100gp per spell level + retail price of scroll)
- This still has the problem of how to pick a fair arbitrary number?
- Give them a set amount they can use on learning new spells. Still an arbitrary number, but atleast one that is more feasible. ie, you can set a max of 30% of wealth be spent on a single item, so the same principal or even cap could be set on learning spells.

No, Warlock Spellslots do not count toward the Multiclass Spellcaster table
Spell Slots. You determine your available spell slots
by adding together all your levels in the bard, cleric,
druid, sorcerer, and wizard classes, half your levels
(rounded down) in the paladin and ranger classes, and
a third of your fighter or rogue levels (rounded down)
if you have the Eldritch Knight or the Arcane Trickster
feature. Use this total to determine your spell slots by
consulting the Multiclass Spellcaster table. - PHB p. 164
Warlock isn't included in that list. Thus you would only have 2 1st level spells as a level 19 warlock, level 1 wizard PC. You could cast level 1 warlock spells using your wizard slots and cast known level 1 wizard spells using your pact magic. Granted you would be able to cast those level 1 spells at maximum level (as per usual with pact magic) but its not going to benefit you in comparison to Eldritch Master which allows you to double your spells per day effectively.
Best Answer
As a Fighter1/Wizard1, you have 2 Spell Slots, and 6 Known Spells
There's two modes of determining your spell slots, based on how your multiclass levels are configured.
All of these important rules, including the rules for Multiclassed Spellcasters, are found in that chapter, for your information.
In your case, because only one class has Spellcasting levels (the Wizard), you'd use rule 1, and simply use your Wizard level and the chart found under the Wizard class to determine your spell slots.
#You Learn and Prepare spells for each of your classes individually, regardless of how many different spellcasting classes you have
This is also found in the Multiclassing rules:
So in your case, you'd continue to use your single Wizard level to determine how many spells you know, and how many you can prepare. If you had levels in other Spellcasting classes, you'd determine your spells for your Wizard individually, then for each of the other Spellcasting classes you have, and then your total known/prepared spells list would be the sum total of each class you have, with the Spellcasting modifier for each spell being based on which class you learned/prepared the spell from.
The number of Known Spells a Wizard has is campaign dependent
Just to make sure it's not left unstated: the number of "Known spells" for a Wizard is a little strange because their class features allow them to learn additional spells if they're given the time and money to copy down spells from a scroll or other source. So as a Wizard, you may very well know more spells than what the Player's Handbook says you should know at a given level. That's a feature that is particular to Wizards, and it is incumbent on you to make sure you understand that if you plan to play a Multiclassed character. Your DM should be able to assist in keeping your spellbook consistent.
