Varying values of what for each year? Interest rate? Exchange rate? Repayment?

Oh sorry, varying values of income each year. Eg. Initial investment is 2,100,000, and the cash flows are Year1: 0, year2: 1,000,000, year3:1,500,000, year4:590,000, year5:800,000, etc

OK, so you want to apply an interest rate to the remaining balance each year?

So have a row for each year, with two columns, one for remaining balance, one for repayment made.

The formula for each year's remaining balance is ((previous year's balance - previous year's repayment) * interest rate). Once the balance reaches zero, the loan is repaid.

You can set up a template in MS Excel as shown in the following image
Your answer is 2.73 years or in other terms 2 years and 9 months

You can get the months by multiplying 0.73 times 12 = 8.76 rounded to 9

payback period = total cost/(total revenue x years)
