Specify order of applying payments
Calin Professional allows you to specify the order in which payments are applied.
When you are calculating interest involving multiple transactions  i.e. more than one debt and/or payment, the result can be significantly affected by the order in which payments are applied.
Calin provides you with the ability to easily select a method of applying payments that suits your situation:
 Lowest Interest  this will select the payment allocation order that will result in the lowest total interest.
 Highest Interest  this will select the payment allocation order that will result in the highest total interest.
 Manually Configure  this lets you choose the exact order you require to comply with contract or legislation.
Use a variety of interest rate styles
You can select from five types on interest rates.
 Static Rate  a simple rate such as 7.5%
 Stored Variable Rate  accommodate any number of rate changes, and the rates can change according to amount as well as date. These can be created and reused  *or one of the subscription rates if applicable to your edition.*
 Custom Rates  have all the sane characteristics as a Stored Variable Rate  except that you don't save the rates in a separate reusable file. Instead, the rates are stored as part of the calculation. You can use this for ad hoc calculations that need tiered interest rates but won't be needed on a regular basis.
 Multiple Phases  lets you to specify different interest rate systems and/or schedules within a single calculation.
 No Interest  no interest will be calculated for the date range. This makes more sense when used with Multiple Phases.
Specify Multiple Phase Interest  different interest rate systems and/or schedules within a single calculation
You can combine different storedvariablerates for different date periods, and can even mix compounding and noncompounding in the same calculation.
For example: a contract that specifies a particular system of normal interest rates, but uses a different rate when in breach, or a situation where legislation says that you use Interest Rate Schedule No 1 until a particular event occurs eg an amended liability is raised, and then Interest Rate Schedule No 2 is used if it is not paid on time. You could also apply completely different variable moratorium rates which override the default rates for particular time spans.
Apply rates on credit balances
If required you can specify a different regime of interest rates for where an account balance is in Credit instead of Debit. By default the rate for interest on Credit balances is "Same as Debits".
Apply moratorium interest rates
Moratorium rates are used to override the interest rate that would otherwise apply. You can use this to reduce the interest rate on hardship grounds  eg during a period of illness, or you can simply use it to modify the prevailing rate on any other ground. Calin lets you override the rate for any number of datespans that you define.
Adjust nominal interest rate
You can adjust the nominal rate by a percentage or multiplier. This is perfect for 'overdraftrate plus n%' situations because you don't have to create a secondary Stored Variable Rate file, or perform the adjustment manually.
Control when rates change
When you use Stored Variable Rates or Custom Rates which specify interest rates that change from time to time, the default assumption is that every time the underlying rate changes, the calculation should adopt the new rate immediately on and from that date. However there are occasions where that is not good enough. For example the applicable interest rate might be linked to some frequentlychanging government rate, and yet in the particular situation, the rate is only allowed to change once or twice a year. Calin accommodates a variety of different options. And can even accommodate systems such as USA Federal where the calculate ratedate has to be further adjusted.
Control when interest accrues
You have full control over when interest is accrued. You can make interest accrue periodically, or at the end of each month, or according to other options as shown here which allow you can match contractual and legislative rules exactly.
Control when compound interest as applied and on what
Calin easy handles compound interest.
 Daily with Rounding Interest will be compounded once per day. Mathematically, this will usually resolve to a decimal fraction such as $0.95.434344378 cents. Rounding means that interest will be rounded every day to the smallest monetary unit  eg $0.95 cents. The purpose of this is to make the calculation easier to follow.
 Daily without Rounding Interest  will be compounded once per day but decimalfractions will not be rounded to the smallest monetary unit (eg cents).
 Scheduled  this gives you the same scheduling powers as for normal Interest.
 Annual  interest will be compounded on the annual anniversary of the calculation's start date.
 Same as Interest  interest will be compounded every time interest accrues  whether daily or some other interval.
 None  No compounding occurs.
