Currently, Mambu only offers calculating tiered credit interest by levels.

For example:

0-$1,000 -> 5%

$1,001 - $5,000 -> 10%

If the balance on the account is $1,500, interest is calculated as 10% of $1,500.

Banks often tier interest by bands to incentivise and manage deposit portfolios.

For example:

0-$1,000 -> 5%

$1,001 - $5,000 -> 10%

If the balance on the account is $1,500, interest is calculated as 5% on $1,000 and 10% on $500.
