HELB penalties & 80% waiver math

MMF vs T-bills after 15% WHT
At October 2026 rates, a 10.50% EAR MMF nets about 8.86% after 15% WHT vs ~7.68% on the 364-day T-bill — a snapshot, not a promise.
Fuliza vs M-Shwari APR cost
KES 5,000 for 7 days on Fuliza costs about KES 260 (~271% APR annualised). Compare break-even days vs M-Shwari’s 7.5% fee.

Velocity banking rate-spread traps
Routing income through a 9.5% HELOC to chunk a 3.5% mortgage can cost more than it saves — unless surplus cash flow is large enough.
0% APR balance transfer break-even
A $15,000 balance transfer looks free until the 3–5% fee and the promo cliff hit. Here’s the break-even math.
Credit card minimum payment decay
Pay only the minimum on $10,000 at 24.99% APR and you may still be paying for 22.7 years — with about $19,236 in interest.
