How do you calculate the total balance with interest?

Back

To calculate the total balance with interest, use the formula: Total Balance = Principal + (Principal x Rate x Time). For example, for a principal of $2,000 at an 8% interest rate for 0.5 years, the total balance is $2,000 + ($2,000 x 0.08 x 0.5) = $2,080.
