Methodology

Methodology: visibly simple.

The calculators are quick plausibility models. They show magnitude and separate assumptions instead of judging a home conclusively.

Everyday models

Rent, move-in, moving and area are calculated with transparent formulas.

Orientation model. Not tenancy-law advice, contract review or structural assessment.

Inputs do not leave the browser.

Calculation path

Monthly load = base rent + service charges + heating + electricity + internet + reserve

Read the output as recurring load: running cost, ratio or per-square-meter value first, then check reserve and assumptions.

Deposit = net base rent × deposit months

Read the output as one-off cost: base amount, buffer and cash gap should stay separate before you commit.

Start budget = first warm rent + deposit + moving + renovation + furniture + kitchen + setup

Read the output as one-off cost: base amount, buffer and cash gap should stay separate before you commit.

Estimate = vehicle + parking zone + helpers + boxes + distance share; then buffer

Read the output as one-off cost: base amount, buffer and cash gap should stay separate before you commit.

Plausible area = full room area + balcony × share + sloped area × share

Read the output as a plausibility check: separate area, usability and differences from the listing.

Person cost = base share + area-dependent share

Read the output as recurring load: running cost, ratio or per-square-meter value first, then check reserve and assumptions.
