Complete Development Cost Calculation
A robust project calculation captures all cost groups of a construction project and compares them to the realistic income side — the result is the project return and the proof of economic viability to financing banks, investors and authorities.
We prepare project calculations for residential and commercial projects of any size — from the small condominium development to the mixed-use district development project — based on current construction costs, market rents and sales prices.
The project calculation includes:
- ✓Land costs including all acquisition ancillary costs
- ✓Construction costs (gross volume/gross floor area) according to the current construction cost index
- ✓Planning & approval costs
- ✓Financing & interim financing costs
- ✓Marketing & sales costs
- ✓Income side: sales prices / rental income
- ✓Project return & sensitivity analysis

Process of the project calculation
Project data & development analysis
Recording of all project parameters: plot size, development rights (development plan / § 34 BauGB), planned usable areas (gross floor area/net usable floor area), type of use, construction schedule and intended exit strategy (individual sale or letting).
Cost determination
Complete calculation of all cost groups: land (including ancillary costs), construction costs based on current cost indicators, planning fees, approval fees, site development, financing costs and marketing.
Income analysis
Determination of realistic sales prices per unit type (residential, commercial, parking space) based on current market data — or rental approaches for the buy-to-hold strategy including income valuation.
Return, break-even & sensitivity
Calculation of the project return (developer profit), break-even analysis and sensitivity assessment for cost overruns, sales price declines and construction time extensions.
