This method of loan repayment is known as loan amortization
Loan Amortization: A loan repayment method structured such that a series of equal periodic installments will be paid for certain number of periods to offset both the loan principal amount and the accrued interest.

Loan amount = A× (1- (1+r)^(-n))/r
A- annual installment
r - annual interest rate
n- number of years,
Loan amount = ?
Loan amount = 100 × (1 - (1+0.04)^(-20) )/ 0.04
Loan amount = 1,359.032
Total amount of principal paid = $ 1,359.03
