How to Use the EMI Planner: Every Field and Result Explained
The EMI Planner tells you what a loan will cost you every month and in total. You need just three numbers — how much you're borrowing, the interest rate and how long you'll take to repay — and it does the rest. This guide goes through every field and every result in plain words, with real examples you can open in one click.

In short
- You only need three inputs: loan amount, annual interest rate and tenure.
- The tenure can be in years or months; switching converts it for you.
- Results update as you type — there's no Calculate button to press.
- Every example in this guide opens the planner with its numbers filled in.
01Quick start in 30 seconds
- Open the EMI Planner (Loans & Debt → EMI Planner).
- Type the loan amount — for example 30,00,000.
- Type the annual interest rate from your sanction letter — for example 8.5.
- Type the tenure and choose Years or Months — for example 20 years.
- Read your Monthly EMI in the green box. That's it.
02Every input, explained
Currency
The currency your loan is in. It changes the symbol and how big numbers are written (lakh and crore for rupees, thousands and millions for others). It doesn't change the maths.
- Example:
- Leave it on ₹ INR for an Indian loan; pick $ USD for a US car loan.
Loan Amount
How much you are borrowing — the money the bank actually lends you, not the price of the house or car. If a flat costs ₹40 lakh and you pay ₹10 lakh yourself, the loan amount is ₹30 lakh.
- Where to find it:
- Your sanction letter calls it the “sanctioned amount” or “loan amount”.
- Example:
- ₹30,00,000 (type 3000000 — the planner adds the commas and shows “30 lakh” underneath).
- Common mistake:
- Don't add the processing fee or insurance to it unless the bank is actually lending you that money too.
Annual Interest Rate
The yearly interest rate the bank charges, as a percentage. The planner divides it by 12 to get the monthly rate it charges on what you still owe.
- Where to find it:
- The sanction letter or loan agreement — look for “rate of interest” or “ROI”. For floating-rate loans, use today's rate.
- Example:
- 8.5 (for 8.5 % a year). Typical ranges in India: home loans 7.5–9.5 %, car loans 8.5–11 %, personal loans 11–18 %.
- Common mistake:
- Don't enter a monthly rate (like 0.71) or a flat rate. If a lender quotes a “flat” rate, the real (reducing-balance) rate is much higher — ask them for it.
Loan Tenure (Years / Months)
How long you'll take to repay. Longer means a smaller EMI but more interest in total. Use the Years | Months switch next to the box: switching converts your tenure (20 years becomes 240 months), so the loan stays the same.
- Where to find it:
- The sanction letter: “tenure” or “term”, often in months for car and personal loans.
- Example:
- 20 years for a home loan, 60 months for a car loan, 36 months for a personal loan.
- Common mistake:
- Typing 60 while the switch says Years means a 60-year loan — the planner allows up to 50 years and will tell you if it's too long.
First EMI Date (optional, under More options)
The date your first EMI is due. Add it and the planner shows the month of your last EMI, and labels the schedule with real months instead of “EMI 1, EMI 2”.
- Where to find it:
- Your repayment schedule or the bank's welcome letter.
- Example:
- 5 November 2026 → your 240th and last EMI falls in October 2046.
03Every result, explained
These are the results for the example above — ₹30 lakh at 8.5 % for 20 years.
Monthly EMI — ₹26,035
What you pay every month for the whole loan. Under it you'll see how many EMIs that is (240) and over how long.
- Example:
- Compare it with your take-home pay: many lenders want all your EMIs under 40–50 % of it, and staying under 40 % leaves a cushion.
Principal Amount — ₹30,00,000
The amount you borrowed, repeated so the totals below make sense.
- Example:
- ₹30,00,000.
Total Interest — ₹32,48,327
Everything you pay the bank on top of the loan itself, if you never prepay. This is the number to make smaller.
- Example:
- Try 15 years instead of 20: it drops to ₹23,17,594.
Total Payment — ₹62,48,327
Loan plus interest: everything you'll hand over by the end. It's simply the EMI × the number of EMIs.
- Example:
- ₹26,035 × 240 ≈ ₹62.48 lakh.
Interest-to-Principal Ratio — 108 %
Total interest as a share of the loan. Above 100 % means you'll pay more in interest than you borrowed.
- Example:
- At 15 years it's 77 %; at 30 years it's 177 %.
Interest in Your First EMI — ₹21,250 (82 %)
How much of your very first EMI is interest. Early EMIs are mostly interest because you still owe almost everything.
- Example:
- Only ₹4,785 of your first ₹26,035 reduces the loan.
Half the Loan Repaid By — EMI 166 (year 14)
The EMI after which you owe less than half of what you borrowed. It's always well past the halfway point in time, because early EMIs are mostly interest.
- Example:
- Add a First EMI Date and this shows a real month instead.
Chart and year-by-year schedule
The bars show how much of each year's EMIs went to principal (green) and interest (lime). The table shows the same for every year, with the balance left and the share of the loan repaid.
- Example:
- In year 1 you pay ₹2,52,709 of interest and ₹59,707 of principal; in year 20 it’s ₹13,921 of interest and ₹2,98,495 of principal.

06Questions people ask
Do I need to press Calculate?
No. The EMI Planner recalculates as you type; if something you entered can't be right, it tells you what to fix next to that field.
Can I use it for a car, personal or education loan?
Yes. Any loan repaid in equal monthly instalments on a reducing balance works the same way — only the amount, rate and tenure change.
Does it include processing fees or insurance?
No — it shows the EMI and interest on the amount you borrow. Add one-time fees separately when you compare offers.
