The minimum lease payments are the lowest amount that a lessee can expect to make over the lifetime of the lease. The minimum lease payments, including a guarantee of a residual if applicable, are used to value the lease by doing a net present value (NPV) calculation. The method of calculating minimum lease payments is laid out in the Statement of Financial Accounting Standards No. 13 (FAS 13), Accounting for Leases.
Occasionally, we get a customer that has a unique situation where they have to do daily payments. Sometimes they are only during the business week and sometimes they are 7 days a week. This is a calculation that you can do in TValue but it takes a little bit of creativity to do it.
If you are interested in manually calculating an interest amount with irregular payments, you need to understand the impact of a stub period in the calculation. Sometimes the calculations are easy to verify and sometimes you may get a hybrid calculation because you have to do two calculations to verify the interest amount.
