Debt Consolidation Calculator
A financial utility for estimating interest savings through loan refinancing
The Debt Consolidation Calculator is a computational tool designed to assist individuals in analyzing the financial implications of combining multiple debt obligations into a single loan. By inputting current debt parameters and prospective consolidated loan terms, the utility determines the potential reduction in annual interest rates and monthly payments.

Calculation Formula
The calculator employs the Equated Monthly Installment (EMI) method to determine payments for both the existing debt load and the proposed new loan. The mathematical model assumes a fixed interest rate calculated monthly on the reducing balance.
Where:
E = Equated Monthly Installment
P = Principal Loan Amount
r = Monthly Interest Rate (Annual Rate / 12 / 100)
n = Loan Tenure in Months
For a more granular breakdown of standard loan payments, refer to the EMI Calculator.
Financial Analysis
Benefits of Consolidation
Debt consolidation is primarily utilized to streamline finances by rolling multiple high-interest debts, such as credit card balances, into a single installment loan. The primary advantage is often a reduction in the weighted average interest rate (WAIR). If the new loan offers a rate significantly lower than the current average, the borrower reduces the cost of borrowing.
Additionally, consolidation simplifies cash flow management. Instead of tracking multiple due dates and varying minimum payments, the borrower manages a single monthly outflow. This is conceptually similar to loan refinancing, though refinancing typically refers to replacing a single existing loan (like a mortgage) with a new one.
Risks and Tenure Extension
A common pitfall in debt consolidation is the extension of the loan tenure. While extending the term (e.g., from 36 months to 60 months) drastically reduces the monthly payment obligation, it may increase the Total Interest Payable over the life of the loan.
As demonstrated in the calculator above, if the “Total Interest Impact” shows a negative value (Loss), it indicates that the lower interest rate is effectively negated by the longer duration of the new loan. Financial advisors generally recommend maintaining the same payoff timeline or shortening it to maximize savings.
