Frequently Asked Questions
Difference between equal payment and equal principal?
Equal payment keeps the total (principal + interest) constant; interest portion is high at first. Equal principal keeps the principal part constant, so payments fall over time and save interest.
When choose a bullet loan?
Bullet loans suit short-term cash needs, expected lump-sum inflow at maturity, or when you need to minimise monthly payments.
What is a grace period?
Months during which you pay interest only. Afterward, monthly payments rise because principal is repaid in the remaining term.
Which method costs least interest?
Equal principal usually yields the lowest total interest, while bullet loans cost the most.
