This calculation is an estimate. Fees, insurance, taxes, changing rates, calendar-day rules, rounding and contract terms can change the actual result.

Good to know

The Loan Calculator supports model calculations for loan payment, term, interest rate, remaining balance, and total repayment. Enter loan amount, interest rate, term, payment frequency, and optional extra payment and review regular payment, total interest, repayment, amortization schedule, and effect of extra payments, so assumptions, magnitudes, and alternatives are easier to compare.

Typical searches include loan payment calculator, loan calculator, amortization schedule. Calculation runs locally in the browser and shows results, intermediate steps, and key figures without upload. Fees, insurance, variable rates, and day-count conventions can change real offers.

Typical use cases

Compare scenarios

Change amount, term, interest rate, payment, or target value and immediately see how the key figures change.

Document assumptions

The core logic is: annuity = principal times periodic rate divided by one minus discount factor. Visible inputs, results, and intermediate steps help explain the model calculation in notes, spreadsheets, or conversations.

Prepare decisions

Use the values as orientation for questions to lenders, tax advisors, employers, providers, or internal planning. The tool does not replace individual advice.

Tips for better results

Separate nominal and real values

Inflation, fees, taxes, and purchasing power can materially change the result. Check whether you are comparing nominal amounts or values in today's purchasing power.

Check contract details separately

Lender offers, credit cards, insurance, taxes, and investment products often use their own rounding, fee, and calendar rules. Binding decisions require the original documents.

Test sensitivity

Run conservative, middle, and optimistic variants. Small changes in rate, term, inflation, or payment can create large differences in financial calculations.

How it works

Step by step

  1. 1

    Enter starting values

    Enter loan amount, interest rate, term, payment frequency, and optional extra payment. Use realistic assumptions and the same currency for related amounts.

  2. 2

    Review the result

    Compare regular payment, total interest, repayment, amortization schedule, and effect of extra payments and account for rounding, term, interest rate, and assumptions.

  3. 3

    Calculate an alternative

    Change one assumption at a time so it remains clear which factor drives the result most.

Features

Local in the browser

Inputs and results are not uploaded for calculation.

Flexible assumptions

Adjust loan amount, interest rate, term, payment frequency, and optional extra payment and compare variants immediately.

Traceable calculation path

Formulas, intermediate steps, and key figures make the model calculation easier to review.

No financial advice

The result is a model calculation, not a recommendation for credit, investing, tax, or contracts.

Frequently asked questions

Is the Loan Calculator financial advice?

No. The tool creates a calculation model based on your inputs. It does not account for your individual situation, a full contract, or personal tax position.

Why can a provider calculate different numbers?

Providers may include fees, day-count rules, rounding, special terms, taxes, bonuses, or contract details that are not part of a general browser calculation.

Are my financial values stored?

No. Calculation runs in the browser. Entered values are not transferred to Xoricon for the calculation.

Why do rounding and currency matter?

Small rounding differences can add up over many months or periods. The currency selection controls only symbol and number format; all compared amounts should already be in the same currency.
