If you are just needing a spreadsheet that you can enter info in and have it do calculations, and don't want to buy MS Office, there's a program called Open Office that you can get free online. Just do an online search and you can find it easily. The spreadsheets calculate just like Excel, and I used it for many years. I would put all the info in and then print it out for our tax accountant. She loved that everything was already broken down by date, amount, etc. - saved her work and me $$.
