About Base Rate To Lending Rate Calculator

A lending rate is built as a reference rate plus a credit spread for the borrower's risk and a premium for tenor. Because the reference rate resets, the borrower's rate moves with it while the spread stays fixed for the loan's life.

Formula

Lending rate build-up

Rate = base rate + credit spread + tenor premium

Frequently Asked Questions

Why is the spread fixed but the base rate not?

The spread reflects the borrower's risk at sanction; the base rate reflects the bank's changing cost of funds.

Can the spread be renegotiated?

Usually only on refinancing or a documented improvement in credit standing.
