Questions people ask
What is future value?
What money today, plus any regular saving, will be worth later at a given rate of growth.
How is it worked out?
The lump sum grows by (1 + monthly rate) for each month, and each monthly payment grows for the months left after it is paid in.
Should I use a real or nominal rate?
Use the rate after inflation (about 2 to 3 points lower) if you want the answer in today’s money.
