Common questions
Snowball or avalanche — which actually wins?
Avalanche (highest APR first) wins on math: you pay less total interest. Snowball (smallest balance first) wins on psychology: you knock off whole debts faster, which keeps people motivated. The calculator shows you the cost of choosing motivation.
How does the extra payment cascade?
Each month, every debt receives its minimum payment. The extra you choose stacks onto the front-of-queue debt (smallest for snowball, highest-rate for avalanche). When that debt is gone, its minimum joins the extra pool and rolls into the next one — that's the snowball.
What if I miss a month?
The interest still compounds. The calculator assumes you don't miss; build a buffer in your budget so you genuinely don't.
Should I prioritize debt or invest first?
If a debt's APR is higher than your expected after-tax investment return, kill it first. Credit cards almost always meet that bar; mortgages often don't. Anything in between is a judgment call.
