# Overdrafts Overview

An overdraft is a revolving credit line that allows Solaris account holders to make withdrawals or payments even if their account balance is zero or insufficient.

Overdrafts function similarly to a credit loan, allowing account holders to withdraw money beyond available funds up to a pre-approved limit. Account holders must pay interest and potential overdraft fees.

## Product specifications

Overdrafts are offered to existing customers with a current account at Solaris.

The offered overdraft limit varies depending on several factors, such as account history, net income, and credit score (e.g., SCHUFA). The overdraft limit amounts generally range from **500 – 5,000 EUR**, though business limits may vary based on risk assessment.
