How the calculation works

The five registers balance to zero. Money in is +, money out is −; r is the rate per payment period.

A worked example
Nominal annual rate (%)
6
Periods
360
Present value
200,000
Payments per year
12
Compounding per year
12
FV
0

Step by step

  1. r = Nominal annual rate (%) ÷ Payments per year = 6 % ÷ 12 = 0.5 %
  2. n = 360 · (1 + r)^−n = 0.166 · (1 − (1 + r)^−n) ÷ r = 166.7916
  3. Payment per period = −(200,000 + 0 × 0.166) ÷ 166.7916 = -1,199.1
  4. Total of 360 payments: 360 × -1,199.1 = -431,676.38 · Interest: 231,676.38

Periods count payments: a 30-year monthly loan has 360. A loan you receive is a positive present value, so the payment comes out negative.

If one input changes

  • Nominal annual rate (%) = 4: Payment per period = -954.83
  • Nominal annual rate (%) = 5: Payment per period = -1,073.64
  • Nominal annual rate (%) = 7: Payment per period = -1,330.6
  • Nominal annual rate (%) = 8: Payment per period = -1,467.53
