EMI Calculator
Work out the monthly EMI, the total interest, and a year-wise amortisation schedule for a construction or home loan, so the client's real constraint is in the room while the design is still moving.
The formula the lenders use
EMI = [P × R × (1 + R)^N] ÷ [(1 + R)^N − 1], where P is the principal, R is the monthly rate (the annual rate divided by twelve, then by a hundred) and N is the tenure in months. It is the reducing-balance method, charging interest on what is still outstanding rather than on the original sum, and it is what Indian banks and NBFCs actually use.
Where the money actually goes
Take ₹50 lakh at 8.5% over twenty years. The EMI is about ₹43,391, so the first year costs ₹5.21 lakh, and the loan shrinks by under ₹1 lakh of it. The rest is interest. The year-wise schedule shows that balance tipping slowly across the tenure, and by the end the interest paid comes to roughly ₹54 lakh, more than the loan itself.
Why the studio needs it
A client's real constraint is a monthly outgoing, not a project total. Move the tenure or the rate and the affordable build moves with it, which is a design conversation as much as a financial one. Having the schedule to hand turns a vague budget into a number both sides can work against.
The number the client actually feels
Clients rarely decide on the total cost of a build. They decide on what leaves their account every month. Putting the EMI beside the estimate means the standard of finish, the built area and the loan get argued about together, once, rather than in three separate meetings that each ignore the other two.
- Reducing balance, the way lenders compute it
- A year-wise schedule, not a single figure
- Total interest shown up front, not discovered
Off the envelope, onto a number
The client budgets the build and forgets the loan.
Build cost and monthly EMI sit in the same conversation.
A flat-rate sum that no Indian lender actually charges.
Reducing balance, the method banks and NBFCs use.
Total interest is a surprise discovered years in.
Every year of the schedule, and the total at the foot of it.
Built to carry the weight
Reducing balance
Interest computed on what is still owed rather than on the original amount, which is the only method an Indian home loan actually runs on.
Year by year
A year-wise amortisation schedule, so a client can see how long it takes before the loan starts genuinely shrinking rather than just being serviced.
Total interest
The whole cost of the borrowing in one figure, which is usually the number that changes what a client is willing to build.
What it asks, what it returns
What it asks
- Principal, the amount borrowed
- Annual interest rate
- Tenure, in years
What it returns
- The monthly EMI
- A year-wise amortisation schedule
- Total interest over the whole tenure
What it assumes
- Reducing balance on a monthly rest
- A fixed rate for the full tenure
- Processing fees and insurance excluded
Three moves, nothing to guess
Enter the loan
Principal, the annual rate the lender has quoted, and the tenure. It works the same for a construction loan or a home loan.
Read the EMI
The monthly instalment, computed on reducing balance exactly the way a bank or NBFC computes it.
Open the schedule
Interest against principal for every year of the tenure, and the total interest paid across the whole of it.
Interest on fifty lakh over twenty years costs more than fifty lakh. A client should see that before signing, not after.
Questions, answered
Straight answers about emi calculator, in plain language.
Ask us anythingReducing balance, using EMI = [P × R × (1 + R)^N] ÷ [(1 + R)^N − 1] with a monthly rest. Interest is charged on the outstanding balance rather than the original principal, which is how banks and NBFCs in India calculate home loan instalments.
No. It is an estimate of the instalment for the numbers you enter. A lender will add processing fees and insurance, may quote a floating rate that resets, and will make its own assessment of eligibility.
Because the client's constraint is usually a monthly figure rather than a project total. Knowing what a given loan costs each month tells you what build the budget can genuinely carry, and it puts your fee in the same conversation rather than after it.
