- Look beyond monthly values to total cost or final value.
- Keep safety buffers before making a decision.
Common mistake
One attractive figure can mislead when fees, taxes, rate changes, volatility or long terms are ignored.
Best next step

How the result is calculated
Monthly payment = loan amount × monthly interest rate × (1 + monthly interest rate)^term ÷ ((1 + monthly interest rate)^term − 1)
Monthly interest rate = annual interest rate ÷ 12
Total repayment excluding fees = monthly payment × term in months
Interest cost = total repayment excluding fees − actual financed amount
Total loan cost = interest cost + one-time fees
If a special repayment is considered upfront, it reduces the financed amount.
Worked example
Example: A loan of €20,000 with an annual interest rate of 6.5% over 60 months results in a fixed monthly payment. If you add up all monthly payments, you get the total repayment excluding fees. The difference between repayment and financed amount is the interest cost. Additional fees increase the total cost further.
Why total cost matters
A low monthly payment can come from a longer term and may increase total interest cost.
