What is the typical relationship between time and interest rate

The relationship between time and interest rate is that they are relatively proportional to each other.

Explanation:

Relative proportionality means that both time and interest rate are wholly dependent on each this means that the more the time given to an investment or debt the more the interest rate receivable or the interest to be paid increases.

Typically interest rates are calculated based on annual basis. another good example of the relationship between interest rate and time the compound interest rate which sees your interest rise overtime as you keep on investing or carrying over debts.
