About Loan Top Up Calculator

A top-up adds to an existing secured loan at close to the original rate, usually far cheaper than unsecured credit. The extra instalment is the difference between the EMI on the combined balance and the EMI on the old balance over the same remaining tenure.

Formula

Top-up EMI

Extra EMI = PMT(out + top, r, n) - PMT(out, r, n)

r
Monthly rate
n
Remaining months

Frequently Asked Questions

Is a top-up cheaper than a personal loan?

Usually much cheaper, because it is secured on the same asset — though it stretches the debt over a longer horizon.

Does a top-up affect eligibility?

Yes. The higher combined EMI is counted against income, and the total must stay within the lender's loan-to-value limit.
