Hi samjesse,

You need to provide a lot more information than that:
• at what frequency is interest calculated?
• does the interest compund, or is only simple interest charged?
• if the interest compounds, does the 10% represent the simple rate (eg 10%/12 monthly calculations) or compound rate (eg 10%^(1/12) monthly calculations)?
• is interest charged on the overdue instalment, or on the whole amount?

• at what frequency is interest calculated?
daily

• does the interest compund, or is only simple interest charged?
simple not compound.


• is interest charged on the overdue instalment, or on the whole amount?
over due instalment.

In that case, for an instalment amount in A1 and an overdue period in B1, the interest would be calculated as:
=A1*10%/365.2425*B1
where 365.2425 is the long-term average number of days in a year.
