Frequently Asked Questions
Fields carrying an asterisk (*) must be completed. Select any ? beside an input or result to open its explanation.
What is Loan Amount?
Loan Amount is the original principal borrowed. Along with the annual rate and repayment period, it is used to establish the regular EMI and projected outstanding balance.
What is Interest Rate?
Interest Rate is the annual rate used to calculate interest on the outstanding loan balance. Enter the annual rate that applies to your loan.
What is Loan Tenure?
Loan Tenure is the planned repayment period. This calculator converts years into monthly payment periods for the loan calculation.
Why is currency selectable?
Currency changes how amounts are displayed and formatted. It does not change the underlying loan mathematics. The calculator keeps the calculation values currency-neutral and applies the selected currency only to the displayed amounts.
What is Current EMI?
Current EMI is the regular payment before your chosen change. The calculator derives it automatically from the loan amount, annual rate and repayment period.
What is New EMI?
New EMI is the payment that takes effect from your selected month. A value above the regular EMI is treated as a Step-Up, while a lower value is treated as a Step-Down.
What does “Starts From Month” mean?
It is the first payment month in which the new EMI applies. For example, Month 13 means the first 12 months use the Current EMI and the new EMI starts with payment 13.
What is a Periodic EMI Change?
A periodic change applies the entered percentage repeatedly at the selected frequency. Use a positive percentage to increase EMI and a negative percentage to decrease it.
What is a One-Time EMI Change?
A one-time EMI change applies a new EMI from one selected month onward. The calculator compares that payment with the Current EMI and automatically identifies it as a Step-Up or Step-Down.
What is a Custom EMI Schedule?
A custom schedule lets you define up to five future EMI changes. Each change has a new EMI and the month when it begins. The calculator checks that the starting months move forward without overlap.
What does the balance chart show?
The balance chart compares the estimated outstanding loan balance under the standard EMI plan with the selected EMI-change plan. A faster-falling line indicates that the balance is being reduced sooner.
What does the repayment composition donut show?
The donut separates the original principal from the interest estimated across the selected repayment schedule. This view highlights the share of the scheduled repayment that represents interest.
What is the month-by-month repayment schedule?
The schedule shows each payment period, EMI, interest portion, principal portion and remaining balance. It is collapsed initially so the page stays easier to scan.
How is time saved or extended calculated?
The calculator compares the number of monthly payments under the standard EMI plan with the number under your selected EMI schedule.
What is Total Repayment?
Total repayment is the sum of the scheduled payments in the selected EMI plan, including principal and interest.
What is Monthly EMI Impact?
It is the difference between your selected EMI and the Current EMI. It shows how much more or less you plan to pay each month after the change.
How is loan payoff time calculated?
The calculator simulates each monthly payment against the outstanding balance. Interest is calculated from the balance for that month, and the selected EMI schedule is applied when each change becomes active.
How is interest saved calculated?
The calculator compares the estimated total interest under the standard EMI plan with the estimated interest under your selected EMI schedule. A positive difference is shown as interest saved; a negative difference is shown as additional interest.
