Bonn sits in an interesting sweet spot. It’s a proper city with good infrastructure, international employers, and Rhine-side living — but it’s notably cheaper than its neighbours Cologne and Düsseldorf. If you’re weighing up the Rhineland, the cost difference is real and worth understanding.
Here’s what a realistic monthly budget looks like in Bonn in 2026.
Rent — The Biggest Line Item
Rent will be your largest expense, typically eating up 35-45% of your net income.
| Apartment Type | Monthly Range |
|---|---|
| 1-bedroom (centre) | €650-850 |
| 1-bedroom (outside centre) | €500-700 |
| 2-bedroom (centre) | €900-1,200 |
| 2-bedroom (outside centre) | €700-950 |
| WG room (shared flat) | €350-500 |
These are Kaltmiete (cold rent) figures. Your actual monthly housing cost will be the Warmmiete, which includes Nebenkosten — heating, water, waste collection, and building maintenance charges, typically adding €150-250 on top.
Compared to Cologne (where a central 1-bedroom often runs €800-1,000) or Düsseldorf (€850-1,100), Bonn offers genuine savings without sacrificing quality of life.
Utilities — The Extras That Add Up
Beyond the Nebenkosten bundled into your Warmmiete, you’ll pay separately for:
- Electricity: €50-80/month for a one-bedroom, depending on your provider and usage. Compare prices on Check24 or Verivox
- Internet: €30-45/month for standard broadband. Telekom, Vodafone, and 1&1 are the main providers. Given that Telekom is headquartered in Bonn, coverage tends to be solid
- GEZ (Rundfunkbeitrag): €18.36/month — the mandatory broadcasting fee. Every household pays this, no exceptions
Total utilities beyond Nebenkosten: roughly €100-145/month.
Groceries and Food
Grocery shopping in Germany is famously affordable compared to much of Western Europe.
- Monthly groceries (single person): €250-320
- Budget shopping at Aldi, Lidl, Penny: Closer to €200-250
- Regular shopping at REWE, Edeka: €280-350
Eating out is where costs climb:
- Lunch at a casual restaurant: €10-15
- Dinner for two at a mid-range restaurant: €40-60
- Döner or street food: €5-7
- Coffee at a cafe: €3-4
Bonn has a good food scene, especially around Südstadt and the Altstadt, but cooking at home makes a big difference to your monthly budget.
Transport
Bonn is part of the VRS (Verkehrsverbund Rhein-Sieg) regional transport network, which also covers Cologne and the surrounding area.
- Monthly VRS pass (Bonn city zone): Around €100
- Deutschlandticket: €58/month — covers all local and regional public transport nationwide. For most people, this is the better deal
- Single ticket (Bonn city zone): €3.00
- Cycling: Bonn is very bike-friendly, especially along the Rhine. A solid used bike costs €100-300
If you’re commuting to Cologne for work (a common setup), the Deutschlandticket covers your regional train rides too.
Health Insurance
Health insurance is mandatory in Germany. Your options:
- Public health insurance (gesetzliche Krankenversicherung): Roughly 14.6% of gross salary plus a provider-specific supplement (Zusatzbeitrag). For an average salary of €45,000, expect around €300-350/month as your contribution (your employer pays a matching amount)
- Private health insurance: Varies enormously based on age, health, and coverage level. Typically €250-500/month
Major providers with good English support include TK (Techniker Krankenkasse), AOK Rheinland, and Barmer.
Phone and Mobile
- Prepaid SIM: €8-15/month for decent data
- Contract (Vertrag): €15-30/month for generous data. Check providers like Congstar, Aldi Talk, or Telekom directly
Entertainment and Social Life
- Gym membership: €25-50/month
- Cinema ticket: €10-13
- Beer at a bar: €3.50-5
- Rhine cruise: €15-25 for a short trip
Bonn’s cultural offerings punch above its weight — the Beethoven-Haus, Bundeskunsthalle, and various museums along the Museumsmeile provide solid entertainment. Many outdoor activities along the Rhine and in the nearby Siebengebirge are free.
Monthly Budget Summary
| Category | Budget Estimate |
|---|---|
| Rent (1BR, Warmmiete) | €750-1,000 |
| Electricity + Internet + GEZ | €100-145 |
| Groceries | €250-320 |
| Transport (Deutschlandticket) | €58 |
| Health insurance (your share) | €300-350 |
| Phone | €15-25 |
| Entertainment | €100-200 |

These numbers assume a single person. Couples can save significantly by sharing rent and utilities. Families should budget for additional groceries, possibly a larger apartment, and any childcare or schooling costs.
Bonn won’t be the cheapest city in Germany, but for the Rhineland region it represents excellent value — particularly if you’re comparing against the rent levels in Cologne, Düsseldorf, or Frankfurt. You get a high quality of life, international infrastructure, and easy Rhine-side living at a price that doesn’t require a finance director’s salary.
