Decision help
What Rental deposit calculator really clarifies.
Use it when you do not want to mix the deposit with warm rent, furnishing budget or first rent. The important part is not to treat the output as one winning number. It is a plausibility value for viewing, acceptance, moving or household planning.
Net base rent, deposit months and available cash show amount and cash gap separately. If an input is estimated, keep it visible. That way you later know which figure came from a contract, offer, measuring tape or bill and which was only a provisional assumption.
