How is the monthly payment calculated?
The payment is calculated using the annuity formula: a fixed monthly payment over the entire term. In the beginning, the interest portion is high; towards the end, repayment dominates.
What's the difference between nominal and effective interest?
Nominal interest is the pure rate. Effective interest includes fees and additional costs — it shows the real cost. This calculator uses the nominal rate.
Can I repay a loan early?
Usually yes, but an early repayment fee may apply. Check the terms of your loan agreement.
How much loan can I afford?
Rule of thumb: your loan payment should be no more than 30–35% of your net income. With BudgetHeld's budget tool, you can see exactly how much room you have.
What interest rate is currently realistic?
It depends on the type of loan, your credit score and the term. Consumer loans are typically 4–8%, mortgage loans 3–5% (as of 2026).
