What each result means

  • Monthly payment = pmt([Interest rate (APR)]÷1200, [Loan term], [Loan amount])
  • Total interest = [Monthly payment]×[Loan term] – [Loan amount]
  • Total of all payments = [Monthly payment]×[Loan term]

Example values

How the main result changes when Loan amount changes and everything else stays at the example values above:

Loan amount Monthly payment
17,500 198.89
26,250 298.33
35,000 397.77
43,750 497.22
52,500 596.66
70,000 795.55

Formula

Monthly payment = L × i ÷ (1 − (1 + i)^−n), i = APR ÷ 12, n = months Total interest = payment × n − L

Worked example

Inputs: Loan amount: $35,000; Interest rate (APR): 6.52 %; Loan term: 10 years.
Results: Monthly payment = $397.77; Total interest = $12,732.90; Total of all payments = $47,732.90.
