Understand simple interest calculation
EXAMPLE:
Bishop’s last bill approval date was July 1, with a $2,000 overdue balance, including $30.00 past interest.
- Determine the days overdue:
- [Billing and aging date] – [Last bill date] = 31 days
- Determine the year portion:
- [Days overdue] / [Number of days in a year] = 31 ÷ 365 = .0849315 years
- Calculate the interest rate portion:
- [Part of one year that has passed] x [Interest rate] = .0849315 × 0.18 = ** .0152876**
- Calculate the interest due:
- [Calculated interest rate] x ([Amount overdue] – [Interest overdue]) = .0152876 × ($2,000.00 - $30.00) = $30.1165
Sage Timeslips US rounds the amount to $30.12 and applies it to the bill
Understand compound interest calculation
EXAMPLE:
Bishop’s last bill approval date was on July 1, with a $2,000 overdue balance, including $30.00 past interest.
- Determine days overdue:
- [Billing and aging date] – [Last bill date] = 31 days
- Determine the year portion:
- [Days overdue] / [Number of days in a year] = 31 ÷ 365 = .0849315 years
- Calculate the interest rate portion:
- [Part of one year that has passed] x [Interest rate] = .0849315 × 0.18 = .0152876
- Calculate the interest due:
- [Calculated interest rate] x [Amount overdue] = .0152876 × $2,000 = $30.5752
