Loan calculator and loan comparison: work out your instalment loan and find the best offer
Enter amount, term and interest rate: the calculator shows the monthly rate, the interest cost and the total repayment. For real, comparable offers from several banks, open our partner PROCHECK24 comparison afterwards or ask us directly.
How does a loan calculator work out the monthly rate?
It assumes an annuity loan with a fixed rate: the instalment stays the same, the repayment share grows and the interest share falls. Amount, term and rate give the monthly rate, the interest cost and the total repayment. The rate you actually get is only shown in an offer; it depends on creditworthiness, amount and term.
Non-binding guide using an annuity rate and a fixed interest rate. The actual offer depends on creditworthiness, amount and term; the effective rate in the offer is what counts.
The comparison calculator is operated by our cooperation partner PROCHECK24 and opens in a new tab; your entries there go to PROCHECK24, not to Perini Finance & Property. If a placement succeeds we receive a commission — this does not change your terms.
Loan comparison: why offers from several banks make the difference
At the same amount and term, rates differ noticeably between lenders. A comparison through our partner PROCHECK24 shows real offers instead of averages.
Always compare the effective rate, not the nominal rate. Also check the option of extra repayments and the terms for early repayment.
Depending on the process, requests through comparison portals can trigger a credit check. You see how it works in the individual case before you submit.
Which loan fits: instalment loan, renovation loan or mortgage?
Up to roughly €50,000 an instalment loan without a land registry entry is common; above that a mortgage-backed loan or a top-up of an existing mortgage is often cheaper.
Instalment loan: fast, no land registry, rate usually a little higher. Mortgage-backed loan: more effort, usually a lower rate, sensible for larger amounts, also with KfW funding. Refinancing: an expensive loan is replaced when the new rate is clearly lower.
Term and rate: what the levers do
A shorter term lowers total interest but raises the monthly rate; a longer term does the opposite.
Try two or three terms in the calculator and choose the rate your budget can carry permanently.

Frequently asked questions
What is the difference between nominal and effective rate?
The nominal rate is the pure loan rate; the effective rate also includes costs that belong to the loan and is the figure to compare offers by.
How large can the loan be?
Instalment loans are usually available up to around €50,000 depending on lender and creditworthiness. For larger amounts look at a mortgage-backed loan.
Can I repay early?
For consumer loans early repayment is generally possible and any compensation is capped by law. Check the contract terms before signing.
What does the brokerage cost you?
Nothing. If a placement succeeds we receive a commission from the lender; this does not change your terms.
Which rate does the calculator use?
The rate is your own entry. We do not store a bank rate because it depends on the individual case. The offer shows the real rate.
What is an instalment loan?
An instalment loan has a fixed term and a constant monthly rate. It needs no mortgage charge and suits renovation, purchases or refinancing existing loans.
How does the loan comparison work?
You enter purpose, amount and term and receive offers from several banks that you can sort by effective rate and instalment. You start the comparison on this page after one click.
Comparing loans: which loans can I calculate here and what should I look at?
You can calculate and compare instalment loans for renovation, refurbishment, heat pump, solar PV and roof work, plus refinancing of existing loans. When comparing loans the effective rate counts, together with the instalment, the term and the terms for extra and early repayment.
