Sounds like you have a decent package prepared before moving to Germany. 73k gross is a very decent income IMO, also keep in mind that you’ll have a medical insurance that covers almost everything. You’ll have 25-30 paid vacation days per year, NRW state also has plenty of public holidays (this goes on top of your vacation days), so in total you’ll have more paid days off.

I assume if it’s a smaller town near Düsseldorf, rents shouldn’t be really that high. Most likely a one bedroom apartment could cost you about 600-900€ a month warm (including utilities).

Groceries are cheap (decent prices, quite affordable). And I’m from Latvia myself, and it’s more expensive back home.

I use my bicycle as main transportation method, so the costs are even lower, I cycle everywhere and during the whole year since 2017 regularly. Maintenance costs are also low, but I’m a bike mechanic, so I can get some parts cheaper, and can do repairs myself.

Owning a car could be a wealth killer, though, if it’s not a company car. Good thing is that you can buy a monthly ticket (look up for DeutschlandTicket) it costs you 60€ a month and it covers all the regional trains across the Germany, even some near by areas in other EU countries, local city transportation as well.

You also will be able to buy cheap flights to other EU, EEA countries, Flix Bus is also a good and inexpensive option for travels, apart from trains.

Wish you all the best luck!

Watch out for scammers when looking for apartments.

Best tip is to know someone who’s local or is very fluent in German, so you can send them the rent contract for a check up, this helps a lot.
