With this free tool, you can calculate loan payments, repayment, and term for loans — ideal for home construction, real estate financing, and other credits. Choose from 4 flexible calculation modes (monthly payment, loan amount, interest rate, or term) and receive detailed amortization schedules and cost analyses.
Select Calculation Mode
Choose what you want to calculate: monthly payment, loan amount, interest rate, or term. You must enter the other three values. Example: If you want to know how much you can afford, select "Calculate loan amount" and enter your desired payment.
Enter Loan Amount
Enter the desired loan amount (e.g., $300,000 for real estate financing). This is the net loan amount without additional costs like notary fees or real estate transfer tax. Plan an additional 20% equity for better conditions.
Set interest rate
Enter the annual interest rate (e.g., 3.5%). This is the effective annual rate your bank offers. Compare different offers — even 0.5% difference can amount to several thousand dollars over the term. Current rates range between 2.5% and 5%.
Determination term
Select the loan term in years or months (e.g., 20 years or 240 months). Shorter terms mean higher monthly payments but lower total costs. Longer terms reduce monthly burden but significantly increase interest costs.
Calculate and Review Result
Click "Calculate". The tool immediately shows you the calculated value (payment, loan amount, interest rate, or term) as well as total costs, interest burden, and recommended equity. Review the detailed amortization schedule with annual breakdown of interest and principal.
Compare Scenarios
Use "New Calculation" to test different variants. Compare e.g., a 15-year financing with a 25-year financing or different interest rates. This way you find the optimal balance between monthly burden and total costs for your financial situation.

Tips for optimal loan conditions
Use these expert tips to get the best conditions for your loan and save money long-term.
- Compare multiple offers: Get at least 3-5 financing offers from different banks. Use the Loan Calculator to objectively compare all offers. Always pay attention to the APR, not just the nominal rate.
- Maximize your down payment: The more down payment you provide (ideally 20-30%), the better conditions you receive. Banks reward higher down payments with lower interest rates. This often saves tens of thousands over the term.
- Choose the right term: Short terms (10-15 years) save interest but increase monthly burden. Long terms (25-30 years) lower the payment but cost more interest. Use the calculator to find your personal balance.
- Secure extra payment rights: Agree to at least 5-10% extra payment per year. This allows you to pay off the loan faster during financial flexibility (bonus, inheritance) and save interest without being tied to high base payments.
- Use long fixed-rate periods: At low interest rates, fixed-rate periods of 15-20 years are worthwhile. You protect yourself from future rate increases. At high rates, shorter terms (5-10 years) are more flexible for later refinancing.
Frequently Asked Questions (FAQ)
A loan calculator is an online tool for calculating loans and mortgages. It can compute four different values: monthly payment, loan amount, interest rate, or term. You enter three known values, and the calculator automatically determines the fourth value. Ideal for planning real estate financing, car loans, or other credit arrangements.
The loan calculator offers four flexible modes: (1) Calculate monthly payment – with known loan amount, interest rate, and term. (2) Calculate loan amount – how much you can afford with a specific payment. (3) Calculate interest rate – what rate is needed for your desired financing. (4) Calculate term – how long you need for repayment. Simply select the desired mode.
Select "Calculate monthly payment" mode and enter loan amount (e.g., $300,000), interest rate (e.g., 3.5%), and term (e.g., 20 years). The calculator shows your monthly payment as well as total costs and interest portion. Calculation follows the annuity formula: R = K × (p × (1+p)^n) / ((1+p)^n - 1), where p is the monthly interest rate.
Select "Calculate loan amount" and enter your maximum monthly payment (e.g., $1,500), current interest rate (e.g., 3.5%), and desired term (e.g., 25 years). The calculator determines the maximum loan amount you can afford. Note: Additionally, you should plan for 20% equity.
Banks typically recommend an equity share of at least 20% of the loan amount. Example: For a $300,000 loan, you should have $60,000 in equity. Benefits: Better interest rates, lower risk, lower monthly burden. Without sufficient equity, banks often charge higher interest rates or decline the financing.
The amortization schedule shows the annual development of your loan over up to 10 years. You see: initial debt, interest payment, principal portion, and remaining debt for each year. Important: Initially you pay more interest, later more principal. The remaining debt decreases each year. Use this for control and comparing different scenarios.
The interest burden is the total amount of interest you pay over the complete term. Calculation: Total costs minus loan amount. Example: With a $300,000 loan and $450,000 total costs, the interest burden is $150,000 (50% of the loan amount). The lower the interest rate and shorter the term, the lower the interest burden.
Yes, use the calculator multiple times with different values. Compare e.g.: (1) Short term with higher payment vs. long term with lower payment. (2) Different interest rates to evaluate offers. (3) Various loan amounts for budget planning. Save results as screenshots or note down the most important values.
The calculator shows pure loan costs (interest + principal). Not included are: processing fees (often 1-2%), notary costs, land registry fees, real estate transfer tax, broker fees, insurance (residual debt insurance, property insurance), and ongoing costs for real estate. Plan an additional 10-15% of the loan amount for these costs.
The calculator is suitable for annuity loans – the most common loan type for real estate. Here monthly payments remain constant. For bullet loans, interest-only periods, or forward loans, calculations differ. With variable interest rates, payments can change. For precise financing plans, you should additionally consult a bank advisor.
