In this lesson
How banks pay interest is part of Interest Grows Savings. This preview shows how interest-growth connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.
Think about this money choice
Imagine this situation: Bank A compounds interest monthly. Bank B pays interest once a year. Both offer 12% annual rate on your 100000 in local currency.
How it works
Daily crediting means each day's interest is added to the principal. Tomorrow's interest is calculated on today's slightly higher balance. This is daily compounding — the most frequent and highest-earning frequency.
Apply it to a real decision
Real-life money moment: You have 50000 in local currency. Bank A: 8% paid annually. Bank B: 8% paid monthly.
