Plan your home purchase

Does this home fit your budget?

What would the purchase mean for your monthly payment?

This estimates the initial payment for an annuity loan. It is a guide, not a financing offer.

Enter your estimated total rate. Actual costs depend, among other things, on the German state and the purchase.

Use a period to group thousands and a comma for cents.

The payment includes interest and initial principal repayment. Ongoing costs, reserves, insurance and changes after the fixed-rate period are additional.

Open calcimo for a more detailed assessment. Purchase price, interest and initial repayment will be carried over. Equity and the flat purchase-cost assumption in this quick check are not part of its main calculation and need separate review there.

Homebuyer guide

The loan payment is not your total housing cost.

Before buying, look beyond the asking price at acquisition costs, the loan you need and the expenses that continue after you move in.

What are purchase costs?

They typically include real estate transfer tax, notary and land register fees, and sometimes an agent's commission. The amount depends on the transaction. The percentage in this calculator is an adjustable assumption, not a fixed rate.

Simplified example

A €400,000 purchase with assumed costs of 10% adds €40,000. With €80,000 in equity, the estimated loan is €360,000.

How is the initial monthly payment estimated?

A rough formula is loan × (annual borrowing rate + initial repayment rate) ÷ 12. A €360,000 loan at 4% interest and 2% initial repayment produces €1,800 per month at the start. Repayment reduces the outstanding balance; real loan terms, duration and refinancing can change the result.

What else belongs in your household budget?

Allow for running costs, insurance, maintenance and possible renovations. For an apartment, review service charges, reserves and decisions by the owners' association. Keep a buffer for unexpected bills. Compare your total monthly burden with your available income and test a cautious case with higher interest or extra repairs.
