Any of these variables may be the independent variable (the sought-for answer) in a given problem. For example, one may know that: the interest is 0.5% per period (per month, say); the number of periods is 60 (months); the initial balance (of the debt, in this case) is 25,000 units; and the final balance is 0 units.
A formula that is accurate to within a few percent can be found by noting that for typical U.S. note rates (< % and terms =10–30 years), the monthly note rate is small compared to 1. r << 1 {\displaystyle r<<1} so that the ln ( 1 + r ) ≈ r {\displaystyle \ln(1+r)\approx r} which yields the simplification:
The formula above can be used for more than calculating the doubling time. If one wants to know the tripling time, for example, replace the constant 2 in the numerator with 3. As another example, if one wants to know the number of periods it takes for the initial value to rise by 50%, replace the constant 2 with 1.5.
Payback period in capital budgeting refers to the time required to recoup the funds expended in an investment, or to reach the break-even point. [1]For example, a $1000 investment made at the start of year 1 which returned $500 at the end of year 1 and year 2 respectively would have a two-year payback period.

So if you wanted to put $3,000—with no additional deposits—into a high-yield savings account earning 2% that compounds monthly (12 periods within a year), the APY formula would look like this ...
An amortization calculator is used to determine the periodic payment amount due on a loan (typically a mortgage), based on the amortization process. [1]The amortization repayment model factors varying amounts of both interest and principal into every installment, though the total amount of each payment is the same.
A figure in parentheses (for example ()) means the benefit is payable at the end of the period indicated (12 for monthly; 4 for quarterly; 2 for semi-annually; 365 for daily). Notation to the bottom-right indicates the age of the person when the life insurance begins.
