Fixed vs Variable — What's Right For You?
Fixed Rate
Your rate and payment stay the same for the full term. Best if you value predictability, are at your borrowing limit, or believe rates will rise.
✓ Payment certainty ✓ Easier to budget ✓ Protection if rates rise
Variable Rate
Rate moves with prime. Historically lower than fixed over full amortization periods, but payments fluctuate. Best if you have flexibility and expect rates to fall.
✓ Historically lower cost ✓ Benefits if rates drop ✓ Lower break penalties
