initial loan amount | Use payment instead

Also include:

future value

principal and interest

Equation

PMT = (PV i)/(-/(+i)^n) | PV_k = (PMT (-/(+i)^(n-k+)))/i PP = PMT-i PV_k | | PP | principal portion of payment PV | initial loan amount n | compounding periods i | interest rate k | current period PMT | payment PV_k | present value at beginning of period k

Input values

initial loan amount | $ (US dollars) compounding periods | interest rate | % current period |

Result

principal portion of payment | $ (US dollars)
