I want to get the same value with the result from the excel sheet but the computations yield a different result , anyone has an idea why ? I cant get the -13 percent from the excel?

I think my e Nullish Coalescing Operator is correct also.

#excel

#ts code

this.dealDispositionFormFields.salePrice = 10000000
this.dealDispositionFormFields.brokerCommission = 125000
this.dealDispositionFormFields.transactionCosts = 50000
this.dealDispositionFormFields.netBookValue = 11250000


  calc() {
    this.netProceeds = (this.dealDispositionFormFields.salePrice ?? 0) - (this.dealDispositionFormFields.brokerCommission ?? 0) - (this.dealDispositionFormFields.transactionCosts ?? 0);
    this.netSaleGainLossRate = (this.netProceeds ?? 0) - (this.dealDispositionFormFields.netBookValue ?? 0);
    this.netSaleGainLossPercentage = (this.netSaleGainLossRate ?? 0)/(this.dealDispositionFormFields.netBookValue ?? 0);
  }

#current result
