Falling in love with an apartment you can't comfortably afford is one of the most common — and most stressful — housing mistakes. A little honest math before you start searching saves you from months of financial pressure. Here's how to set a budget that actually works.
1. Start With the 30% Rule
A widely used guideline is to spend no more than about 30% of your net (after-tax) income on rent. If you earn €2,000 net per month, that points to roughly €600 in rent. It's not a hard law — but if you're well above it, your budget will feel tight every single month.
2. Budget for the Warm Rent, Not Just the Cold
In Germany, listings often show the Kaltmiete (cold rent) — the base figure before utilities. What you actually pay is the Warmmiete, which adds Nebenkosten (heating, water, building costs). Always plan around the warm rent, and remember electricity and internet are usually billed separately on top.
3. Don't Forget the Upfront Costs
- Kaution (deposit): Often up to three months' cold rent, paid before you move in.
- First month's rent in advance.
- Moving costs: a van, helpers, basic furniture.
- Setup: internet installation, kitchen items, possibly a fitted kitchen if none is included.
It's wise to have several months' rent saved before you commit to a place.
4. Leave Room for Real Life
A budget that only works if nothing ever goes wrong isn't a budget. After rent and bills, you still need money for food, transport, savings, and the occasional emergency. If an apartment only fits when you skip all of that, it's a sign to look a little lower.
5. Search With Your Number in Mind
Once you know your realistic maximum warm rent, search with it firmly in mind and resist the temptation to creep upward. On HOMY you can focus on rooms and apartments that fit your budget and lifestyle from the start — so you spend your energy on places you can genuinely afford to enjoy.
