TABLE SHOWING COMPOUND INTEREST ON ONE 

 DOLLAR FOR ANY NUMBER OF YEARS UNTIL THE 

 INTEREST EQUALS THE PRINCIPAL. 



THE USE OF THE COMPOUND-INTEREST TABLE. 



The compound interest given in the table is on one dollar, and is always 

 cents, mills, etc., so the principal must be multiplied by it and the product 

 pointed off ~,s in any multiplication involving decimals. 



Example: $450 at 3^. 16years = 450X .6047 = $272.12, the compound interest: 

 then $450 + $272. 12 = $722.12, the amount at compound interest.
