Understand German salary, benefits, rent, visa dates, and moving costs before you make a decision.
Germany Calculators is a free collection of practical tools for people living in Germany or planning a move. It is built for expats, international students, foreign workers, families, and newcomers who need a plain-language starting point before reading official German forms.
The calculators run in your browser and do not require a login. They are designed to explain common everyday questions: how much monthly net income might remain after deductions, how Kindergeld works for children, which Steuerklasse situation to review, whether a rent increase needs a closer look, and how much cash to prepare for the first month in Germany.
Start with the number that affects your next step.
If you are comparing job offers, begin with the Brutto-Netto salary calculator and monthly budget calculator. If you are moving with children, check the Kindergeld calculator and the guide to Familienkasse applications. If you are renting an apartment, use the rent increase checker and move-in cost calculator to understand deposit, warm rent, temporary housing, furniture, and administrative costs.

Read the context behind the calculators.
Calculator results are only useful when you understand the assumptions behind them. The guide section explains German tax IDs, Lohnsteuer, Steuerklasse, Kindergeld applications, and tax refund basics in a way that a newcomer can follow. Each guide is written as practical orientation, not as legal, tax, or financial advice.
Germany Calculators also keeps a methodology page that explains how estimates are produced, what sources should be checked for official decisions, and when values need review. Before signing a contract, filing taxes, or applying for a benefit, always confirm the final answer with the relevant authority, a tax advisor, or a qualified professional.
Free, browser-first, and transparent about limits.
The site is operated by Leekai, an independent developer based in Germany. The goal is to make everyday German paperwork and money questions less intimidating for people who are still learning the system. The tools do not replace official calculators from government agencies, but they help you prepare better questions before you use them.
