Hello, I am trying to figure out a formula that will: Determine ending number from a starting number based on a monthly % decline a well as a static number monthly decline...Example below...First column is months, second column starting number, third column a 1k decline per month and 4th column a .005 rate of decline. Each row recalculates by reducing the number above it by the 1000 and the "rate". How can I get to the final number using a formula? I can do it for just the rate but the monthly static number is throwing it off. Thank you
