Buy-Here-Pay-Here Car Math
Buy-Here-Pay-Here Car Calculator — True Cost Trap
What this calculator does
Buy-here-pay-here lots often charge weekly payments for years. This calculator compares that cost to saving for a few months and buying a cheaper used car.
The math, with a worked example
Lot cost = weekly payment × 104. Alternative cost = bus pass × 12 + used car price. Savings = lot cost − alternative cost. A $75 weekly payment for two years costs $7,800. Taking the bus for 12 months and buying a $4,000 car saves thousands.
Why this matters
Buy-here-pay-here lots sell payments, not cars: $75 a week for 2 years is $7,800 for a car worth a fraction of that. The comparison that breaks the spell is 12 months of bus passes plus a $4,000 cash car — thousands cheaper, no repossession risk.
Methodology and transparency
Lot cost = weekly payment × 104 weeks; alternative = 12 months of transit + a saved-for used car; savings = the difference. The model's patience assumption is the honest objection — the alternative requires living without a car while saving, which isn't possible for every job or family. But the lot's unpriced risks cut the other way: BHPH loans commonly carry repossession on a missed payment or 2, losing both car and everything paid.

Common questions
Are BHPH cars overpriced?
Often yes, and interest rates are high. This calculator focuses on the weekly payment trap.
What about car repairs?
The alternative is a cash used car. Maintenance is real but usually far less than BHPH total cost.
