Key Terms Explained
- Principal
- The original amount borrowed or invested, before any interest is applied.
- APR
- Annual Percentage Rate — the yearly cost of a loan including fees, which is what makes it comparable between lenders.
- Compounding
- Earning interest on previously earned interest. Frequency (monthly vs annually) meaningfully changes the total.
- Amortisation
- The schedule showing how each payment splits between interest and principal over the life of a loan.
Pro Tips & Best Practices
