How to Calculate Rental Yield: Formula, Examples, What Investors Check
Calculating the rental yield is the quickest reality check for an investment—and at the same time, the metric that’s most often embellished. At Sweet Home Berlin, we use the gross yield only as a filter and the net yield as the basis for our decisions.
In this guide, you’ll find formulas, two worked-out examples, and the typical pitfalls in Berlin (utility costs, tenancy law, Capex).

Gross Rental Yield: The Simple Formula
The gross rental yield compares the annual base rent to the purchase price—excluding closing costs and ongoing ownership expenses. This approach aligns with common guides, such as Finanztip, on rental yields.
Formula:
Gross rental yield (%) = (Annual base rent ÷ Purchase price) × 100
Annual base rent = monthly net base rent × 12 (excluding operating costs, which you simply pass on).
Alternative calculation using square meters:
Gross (%) ≈ (Base rent €/m² ÷ Purchase price €/m²) × 100
Example 1: Gross Rental Yield
Assuming:
- Purchase price: €400,000
- Monthly net base rent: €1,333
- Annual base rent: €16,000
Calculation: (16,000 ÷ 400,000) × 100 = 4.0% gross rental yield
This is a useful initial filter—but not yet a basis for a purchase decision. Unaccounted-for costs can quickly reduce the actual yield by 1–2 percentage points.
Net rental yield: the more accurate calculation
The net rental yield takes into account incidental purchase costs and non-apportionable operating expenses.
Formula (practical):
Net rental yield (%) = (annual base rent − non-pass-through costs) ÷ (purchase price + closing costs) × 100
Incidental purchase costs in Berlin include, in particular, real estate transfer tax (6%), notary/land registry fees, and, if applicable, real estate agent fees—see “Incidental Purchase Costs in Berlin” for an overview and “Real Estate Transfer Tax in Berlin” for details on the tax.
Example 2: From Gross to Net
Let’s expand on Example 1:
- Purchase price: €400,000
- Additional purchase costs (assumed 11%): €44,000
- Total investment: €444,000
- Annual base rent: €16,000
- Non-recoupable costs per year (management, maintenance, vacancy buffer): €3,200
Net annual income: 16,000 − 3,200 = 12,800 €
Net rental yield: (12,800 ÷ 444,000) × 100 ≈ 2.9%
So, a 4.0% gross yield translates to roughly 2.9% net—before financing and taxes even come into play. This is exactly why “4% in the property listing” is rarely enough.
Rent-to-Price Multiplier: The Reciprocal
Many investors think in terms of multiples of the annual rent:
Multiplier = Purchase price ÷ Annual base rent
In the example: 400,000 ÷ 16,000 = 25× (equivalent to 4% gross).
Rule of thumb: The higher the multiplier, the lower the gross rental yield. Whether 22× is “expensive” or 28× is “okay” depends on location, condition, and tenant protection—not on the number alone.
Factors that particularly influence returns in Berlin
- Actual rent vs. market rent: For rented apartments, the lease agreement matters, not the “dream rent.” See “Buying a Rented Apartment in Berlin.”
- Tenant Protection Laws: Rent increases and termination rules affect cash flow. Overview: Tenant Protection Laws in Berlin for Buyers.
- Price levels by location: High prices per square meter (€/m²) depress the gross yield if rents do not rise proportionally. Context: Real estate prices in Berlin.
- Capex: Roof, facade, elevator, energy—any approved improvements must be factored into the calculation before signing with the notary.

Cash Flow After Financing (Quick Check)
Even a solid net rental yield means little if the mortgage eats into your monthly surplus. Do a rough check:
- Monthly rent (excluding utilities) − non-pass-through costs / 12 − interest and principal payments
- Buffer for vacancy (e.g., 1 month every few years)
- Special assessments by the homeowners’ association
The goal isn’t “maximum leverage,” but a scenario you can sustain even under interest rate or vacancy stress. Sweet Home Berlin will work this through with you before emotions take over the Excel file.
Common Mistakes When Calculating Rental Yield
- Using gross rent instead of net rent
- Omitting closing costs
- Assuming maintenance costs of €0
- Using market rent instead of actual rent for rented properties
- Comparing only gross figures and ignoring net figures
Example 3: Comparing Two Properties
Suppose you are comparing two existing apartments:
| Property A (central) | Property B (entry-level) | |
|---|---|---|
| Purchase price | €520,000 | €340,000 |
| Annual base rent | €18,200 | €14,280 |
| Gross rental yield | 3.5% | 4.2% |
| Service charges (11%) | 57,200 | €37,400 |
| Non-pass-through costs per year | €3,600 | €3,000 |
| Net rental yield (rounded) | ≈ 2.5% | ≈ 3.0% |
On paper, Property B appears to offer a higher yield. Whether it’s a better choice depends on the quality of the location, rentability, capex, and resale potential. That’s exactly why, at Sweet Home Berlin, no analysis stops at the gross rental yield.
What costs should be included in the net calculation?
You should at least factor in these categories—even if the estimate is rough at first:
- Purchase: Real estate transfer tax, notary fees, land registry fees, real estate agent fees
- Operating Costs (non-pass-through): Property management, maintenance reserve, insurance premiums not passed on to tenants
- Vacancy: realistic buffer; do not assume zero
- Capex: known renovations, energy, major repairs
Financing costs belong in the cash flow after the loan, not necessarily in the traditional net rental yield before financing. You need both perspectives: the property-specific yield and the liquidity-based monthly calculation.
When a Lower Yield Still Makes Sense
In prime locations, a lower gross return can be acceptable if:
- the rental potential has historically been stable,
- resale liquidity appears favorable,
- Capex and building quality are clear,
- your time horizon is long-term.
Conversely, a high gross yield may be a red flag: micro-location, tenant mix, or a backlog of renovations. Sweet Home Berlin therefore prioritizes properties that you’ll still want to represent even when the Excel spreadsheet no longer looks “pretty.”
Frequently Asked Questions
How do you calculate the rental yield?
Gross: Annual base rent ÷ Purchase price × 100. Net: (Annual base rent − non-recoupable costs) ÷ (Purchase price + service charges) × 100.
What is a good rental yield?
There’s no fixed city-wide standard. Lower gross yields are common in expensive downtown locations; the key factors are net yield, risk, and holding period.
Is the gross rental yield sufficient?
Only as a filter. To make a purchase decision, you need the net yield, Capex, and financing.
Is the calculation different for foreign buyers?
The formulas are the same. Additionally, you’ll need to factor in taxes, bank accounts, and closing procedures—see “Foreigners Buying Real Estate in Berlin.”
