What do these numbers mean?
- The main figure is one monthly payment. Total repaid includes principal and interest; total interest is the excess over the borrowed amount. The model uses a fixed rate and excludes fees.
- In decimal numbers, commas separate thousands and a dot separates decimals: 1,234.5 = 1234 + 0.5. ×10^3 means multiply by 1000; ×10^-3 means divide by 1000. Display rounding can make tiny differences between shown totals.
