To include an interest charge on the fuel cost, use this formula: fuel cost x (1 + i/100). At 7 percent interest, this would equal: fuel cost x (1 + .07). For example, calculate the propane cost of $36.40 for Incinerator A at 7 percent interest rate for a year later: $36.40 x (1 + .07) = $38.95.t 7 percent interest, this would equal: fuel cost x (1 + .07).
