10for 10 years). Minimum is 1 year. - Click "Calculate" – The button validates your inputs. If any field is invalid, a red error message appears. Correct the field and recalculate.
Results displayed:
- Monthly Payment – Fixed amount due each month.
- Total Interest – Total interest paid over the loan term.
