Upcoming payments

How the math works. Each month, interest accrues on every balance (rate ÷ 12). You pay the minimum on every debt; whatever is left of your monthly payment becomes the snowball, which is thrown entirely at the target debt. When a debt clears, its freed-up minimum and the snowball roll onto the next debt in order — the payments accelerate as you go. Snowball targets the lowest balance first (fast wins); Avalanche targets the highest rate first (least interest). All figures round to the cent the same way a spreadsheet does, and the schedule runs for as many months as it takes to clear every debt. Estimates only — your lender's exact terms may differ.
Due days are for scheduling only — they place each month's payment on a real calendar date in the schedule and the upcoming-payments list, but interest is still computed monthly, so the payoff date and totals are unchanged whether or not you set them. A debt with no due day is treated as the 1st.
