SAC vs PRICE: Which Amortization System Is Better?

SAC vs PRICE: Which Amortization System Is Better?

When financing a car, home, or any other major purchase, one of the first decisions you may face is choosing between the SAC and PRICE amortization systems.

Both methods are widely used by financial institutions, but they calculate loan payments differently, directly affecting your monthly installments and the total amount paid over the life of the loan.

In this guide, you will learn how each system works and which one may be the best fit for your financial goals.

What is the PRICE system?

The PRICE system keeps monthly payments almost the same throughout the entire financing period.

During the first months, most of each payment goes toward interest. As the loan balance decreases, a larger portion of the payment is applied to the principal.

What is the SAC system?

The SAC (Constant Amortization System) keeps the principal repayment constant throughout the loan.

Because interest is calculated on a continuously decreasing balance, the monthly payments start higher and gradually become smaller over time.

Main differences

Feature	PRICE	SAC
Monthly payments	Fixed	Decrease over time
Initial payments	Lower	Higher
Total interest	Usually higher	Usually lower
Best for	Predictable budgeting	Long-term savings

When should you choose the PRICE system?

• If you prefer fixed monthly payments.
• If you want a more predictable monthly budget.
• If you need lower initial installments.

When should you choose the SAC system?

• If you can afford higher initial payments.
• If your goal is to reduce total interest costs.
• If you want to save money over the lifetime of the loan.

How can you compare both systems?

The most reliable approach is to simulate both amortization methods using the same loan amount, interest rate, and repayment period.

This allows you to compare:

• Monthly payments.
• Total interest paid.
• Total financing cost.
• Amortization schedule.
• Outstanding loan balance over time.

Frequently Asked Questions

Is the SAC system always better?

Not necessarily. While it often results in lower total interest, it also requires higher initial monthly payments.

Is the PRICE system more expensive?

In many financing scenarios, the total amount paid is higher, but it offers stable monthly payments throughout the loan.

Should I compare both options before signing a financing agreement?

Yes. Comparing both systems helps you understand the long-term financial impact and choose the option that best matches your budget.

Conclusion

Neither amortization system is universally better. The ideal choice depends on your financial situation, repayment capacity, and long-term objectives.
