Formulae related to loan calculator

Loan Payment formula
\(P\quad =\quad \frac {r\quad (PV)}{1 (1+r)^{n}}\)
In the above equation, one can see that the terms used in the equation mean the below listed things – P is for the payment on one hand whereas on the other hand, the present value is represented by PV. Besides this, the rate per period is denoted by r while the duration or the number of periods are represented by the value n.

2^{nd} Loan payment formula
One will be surprised to know but there is yet another formula to calculate the loan payment & it has been given here as well –
\(P\quad =\quad \frac { P\quad V}{P\quad V\quad I\quad F\quad A}\)
In the above equation, one will get to know that P stands for the payment or the loan amount. Furthermore, PV is the present value. Finally, the variables are replaced by PVIFA in the formula mentioned above.

Balloon balance of the loan
\(F \quad V \quad = \quad (\quad 1 \quad + \quad r\quad )^{n}\quad \quad P\quad [\frac{(\quad 1 \quad + \quad r\quad )^{n}\quad – \quad 1]}{r}]\)
According to the above stated equation, FV means the balloon balance or the future value whereas the present value or the original balance means PV. The payment is represented by P, rate per payment means r & n is the number of payments.

Remaining balance on loan
\(F \quad V \quad = \quad (\quad 1 \quad + \quad r\quad )^{n}\quad \quad P\quad [\frac{(\quad 1 \quad + \quad r\quad )^{n}\quad – \quad 1]}{r}]\)
\(PV(1+r)^{n}\) is FV of the Original Balance;
\(P\frac {(1+r)^n1}{r}]\) is FV of annuity

Annuity payment PV
\(P\quad =\quad \frac {r\quad (PV)}{1 (1+r)^{n}}\)
Here, P means payment, PV = present value, r = rate per period & n = number of periods.
