How this calculator works
People search for a BOI home loan EMI calculator when they already have Bank of India in mind: a branch quote, a salary or savings relationship, a Star Home Loan discussion or a balance-transfer comparison with another PSU or private lender. This page reuses the same reducing-balance engine as our Home Loan EMI Calculator, with Bank of India–oriented defaults, examples and FAQs.
Enter the financed principal (sanctioned loan), the annual rate (% p.a.) from your quote and tenure in years. You get monthly EMI, total interest, total payment and a year-by-year schedule. Figures are indicative estimates from Kalkulator.in, not a Bank of India offer or approval.
After you know the EMI, check comfort with the loan affordability calculator. Lender capacity is a separate question on the loan eligibility calculator or the home loan eligibility calculator. Comparing other providers? See SBI, HDFC, ICICI, LIC or Axis Bank.
- Enter the Bank of India home loan amount (financed principal, not full property price if you pay a down payment).
- Enter the annual interest rate (% p.a.) from the quote you are comparing.
- Enter tenure in years (up to 30 on this page).
- Read monthly EMI, total interest and total payment, then open the schedule for the principal vs interest split by year.
Formula
EMI = P × r × (1+r)^n / ((1+r)^n − 1)
When r > 0. If r = 0, EMI = P / n.
This page uses the standard reducing-balance EMI identity, the same method as the parent home loan EMI calculator. Interest each month is on the outstanding principal, not on the original amount for the full tenure.
P= financed principal (₹ loan amount)r= monthly rate = annual % p.a. ÷ 12 ÷ 100n= number of months = years × 12
Example conversion: 8.55% p.a. → r ≈ 0.007125. For 20 years, n = 240.
Assumptions: Fixed rate for the full tenure sketch; equal monthly instalments; no processing fee, insurance, stamp duty, registration, floating reset or Smart Home overdraft set-off unless you fold those into the inputs yourself. Method detail: how EMI is calculated.

More about this calculator
Why a BOI-specific EMI page
A generic home loan EMI tool answers the math. A Bank of India–framed page answers the next questions borrowers usually ask after seeing a BOI quote: what principal to enter, how long a housing tenure can run, how RBLR-linked floating rates and CIBIL-linked spreads change EMI and how Star Smart Home overdraft features change cash flow without changing the core EMI identity.
This is still the same reducing-balance formula as the EMI calculator hub. It is not an official Bank of India calculator and does not pull live BOI rates.
Bank of India home loan products that affect EMI thinking
Bank of India markets several housing products under the Star Home Loan family. Most still repay with a reducing-balance EMI once full instalments start. Product choice changes what you enter and how you interpret the result:
- Star Home Loan: purchase, construction or related housing needs with a floating (typically RBLR-linked) rate and a regular EMI from disbursal (or after full disbursal on under-construction property).
- Star Smart Home Loan: housing finance with an overdraft-style surplus set-off. Surplus cash parked in the linked account can reduce interest for that period; the scheduled EMI identity on this page still assumes a level instalment unless you model a smaller effective balance yourself.
- Star Diamond and higher-ticket variants: pricing and documentation can differ for larger sanctions. Enter the rate and tenure on your letter; the EMI maths does not change.
- Star Pravasi / NRI variants: eligibility and pricing can differ for non-resident borrowers. Use the % p.a. and tenure on your sanction.
- Balance transfer / takeover: when moving another lender’s outstanding to Bank of India, enter the takeover principal (plus any top-up), not the original property price.
Property price vs financed principal
Enter the amount Bank of India sanctions after down payment and LTV limits, not the full agreement value. Stamp duty, registration and incidental costs are usually cash at purchase, separate from EMI. Estimate duty with the stamp duty calculator where it applies.
Interest rate discussion (do not treat as live BOI pricing)
Bank of India home loan rates on adjustable products are typically linked to an external benchmark such as the repo-linked lending rate (RBLR), plus a customer-specific credit risk premium. Many retail offers also vary with credit-score bands. Your offer letter rate depends on product, ticket size, profile, relationship and promotional windows. Rates change. This page never hardcodes a “current BOI home loan rate.”
Enter the % p.a. on your quote or sanction. Then stress about +0.5% to +1% to see how EMI and total interest move if the floating rate resets upward. Context: fixed vs floating interest.
Typical tenure
Housing tenures at Bank of India commonly run up to about 30 years, subject to age at maturity and product rules. Longer tenure softens EMI and raises lifetime interest. Shorter tenure does the opposite. Stress at least two tenures on this page before you call any EMI comfortable.
Real-world examples
Chip presets match the scenarios below. Load a chip so the calculator lines up with the numbers. Rates below are illustrative planning rates, not published Bank of India tariff claims.
Example 1: first-home BOI sketch (page defaults)
Situation: a household comparing a Bank of India Star Home Loan sanction for a first home uses a mid-long tenure and an illustrative RBLR-linked rate.
Given: principal ₹50,00,000 · rate 8.55% p.a. · tenure 20 years (240 months).
Convert: monthly rate r ≈ 0.007125; n = 240.
Result: monthly EMI ≈ ₹43,549.52 · total interest ≈ ₹54,51,884.86 · total payment ≈ ₹1,04,51,884.86.
Takeaway: Over 20 years interest still exceeds the principal. Soft monthly EMI still means a large lifetime housing cost. See the insight block below for shares and ratios on these defaults.
Example 2: same ₹50 lakh @ 8.55%, tenure 15 vs 20 vs 25 vs 30 years
Situation: the same BOI-sized ticket; only the repayment clock changes while the family budgets monthly cash flow.
Only tenure changes. Principal ₹50,00,000 and rate 8.55% p.a. stay fixed.
| Tenure | Monthly EMI | Total interest | Total payment |
|---|---|---|---|
| 15 years (180 months) | ₹49,383.63 | ₹38,89,053.57 | ₹88,89,053.57 |
| 20 years (240 months) | ₹43,549.52 | ₹54,51,884.86 | ₹1,04,51,884.86 |
| 25 years (300 months) | ₹40,429.97 | ₹71,28,990.03 | ₹1,21,28,990.03 |
| 30 years (360 months) | ₹38,622.99 | ₹89,04,276.72 | ₹1,39,04,276.72 |
Why EMI falls when tenure rises: the same principal is spread over more months. Interest still accrues every month on the outstanding balance, so a longer clock raises total interest.
Decision angle: 15 years costs about ₹5,834 more per month than 20 years, yet saves roughly ₹15.6 lakh in interest. Stretching from 20 to 30 years softens EMI by about ₹4,927 but adds roughly ₹34.5 lakh interest. Pick the tenure your family budget can hold without treating “lowest EMI” as the goal. More on the trade-off: loan tenure guide.
Example 3: floating-rate stress at 20 years (8.55% vs 9.55%)
Situation: the same ₹50 lakh Bank of India home loan on the default 20-year clock; only the rate moves, as on many RBLR-linked housing offers.
Principal ₹50,00,000 · tenure 20 years. Only the rate moves.
| Rate (% p.a.) | Monthly EMI | Total interest | Total payment |
|---|---|---|---|
| 8.55% | ₹43,549.52 | ₹54,51,884.86 | ₹1,04,51,884.86 |
| 9.55% | ₹46,769.93 | ₹62,24,784.22 | ₹1,12,24,784.22 |
Takeaway: +1 percentage point raises EMI by about ₹3,220 and adds roughly ₹7.7 lakh interest over 20 years. On floating BOI-linked quotes, run this stress before you treat the letter EMI as settled for the family budget.
Example 4: higher ticket (₹75 lakh · 8.55% · 25 years)
Situation: a household upgrading to a larger home with a higher Bank of India sanction and a mid-long tenure.
Given: principal ₹75,00,000 · rate 8.55% p.a. · tenure 25 years (300 months).
Result: monthly EMI ≈ ₹60,644.95 · total interest ≈ ₹1,06,93,485.05 · total payment ≈ ₹1,81,93,485.05.
Takeaway: Larger housing tickets amplify both EMI and lifetime interest. Re-check affordability against take-home pay, not only against a lender’s eligibility formula.
What the default result means
Using the page defaults on first load (₹50,00,000 · 8.55% p.a. · 20 years / 240 months), this calculator shows monthly EMI ≈ ₹43,549.52, total interest ≈ ₹54,51,884.86 and total payment ≈ ₹1,04,51,884.86.
Interest is about 52.2% of total repayment, or roughly ₹109.04 of interest for every ₹100 borrowed. Total payment is about 2.09× principal. On this default sketch, interest exceeds the principal itself.
Decision angle: a 20-year EMI at 8.55% still sends about half of every repaid rupee to interest. If family cash flow allows, shortening tenure (try the 15y chip at the same rate) cuts housing interest hard even though EMI rises. Raising the down payment so financed principal falls by ₹10 lakh (₹60 lakh → ₹50 lakh at the same 8.55% / 20 years) lowers EMI by about ₹8,710 and interest by about ₹10.90 lakh. Change the sliders for your sanction; these figures are the default page-load example only.
Rate stress on the defaults (8.55% vs 9.55%)
Principal ₹50,00,000 · tenure 20 years. Only the rate moves from the page default.
| Rate (% p.a.) | Monthly EMI | Total interest | Total payment |
|---|---|---|---|
| 8.55% | ₹43,549.52 | ₹54,51,884.86 | ₹1,04,51,884.86 |
| 9.55% | ₹46,769.93 | ₹62,24,784.22 | ₹1,12,24,784.22 |
Takeaway: +1 percentage point raises EMI by about ₹3,220 and adds roughly ₹7.7 lakh interest over 20 years. Run this stress before you treat a floating-linked BOI quote as fixed.
Processing fees and other cash costs (high level)
Home loan offers can include a processing fee (often a small percentage of the loan with minimum and maximum caps), valuation or legal fees and optional insurance. GST may apply on some charges. Star Diamond–style products can use a different fee schedule. None of these sit inside the default EMI here unless you add fee-loaded principal yourself.
True cash cost is roughly: total payment from this calculator + fees and insurance you actually pay + stamp duty and registration − any rebate you receive. Confirm the fee schedule on your sanction letter, not on a marketing flyer.
Prepayment and foreclosure (high level)
Paying extra principal early usually cuts total interest because future interest is charged on a smaller balance. On many floating-rate Bank of India housing loans for individual personal end-use, prepayment charges are nil. Fixed-rate packages (where offered) or non-individual structures can still attract a percentage fee. Always read your agreement; some lenders also set a waiting period after disbursal before part-prepayment is allowed.
After a part-prepayment, Bank of India (like other lenders) typically lets you choose a lower EMI or a shorter remaining tenure. When a dedicated prepayment tool is available on Kalkulator.in, use that for precise before/after figures; until then, model a smaller principal or shorter remaining tenure here as a rough proxy only.
Smart Home overdraft vs this EMI sketch
Star Smart Home–style facilities can reduce interest when surplus funds sit in a linked overdraft account. This calculator does not simulate daily set-off balances. Treat the EMI here as the contractual instalment sketch, then ask the branch how surplus parking changes interest for your account.
Floating resets: what borrowers usually decide
When the benchmark rises, outstanding home loans can see a higher applicable rate. Common responses are: pay a lump sum to keep EMI and tenure, raise EMI to keep tenure, extend tenure within age limits, or combine those options. This calculator does not simulate reset schedules. Re-enter the new rate (and remaining principal/tenure if you know them) to sketch the next EMI.
Eligibility vs affordability for a BOI ticket
Eligibility asks what income and obligation rules might allow. Affordability asks what your monthly budget can carry after other EMIs, school fees and a buffer for rate resets.
They diverge often on home loans because tickets and tenures are large. Run EMI here first, then the home loan eligibility calculator and the loan affordability calculator. Do not treat max eligibility as the purchase budget.
When a lower EMI is not better
A lower EMI usually means you stretched tenure or cut principal, not that the loan got cheaper. On the ₹50 lakh · 8.55% sketch above, about ₹38,623 for 30 years costs far more interest than about ₹49,384 for 15 years.
Lower EMI is also a weak signal when the quote hides fee-loaded principal, ignores insurance add-ons, or skips stamp-duty cash. Compare total payment and the schedule. Practical levers: how to reduce EMI.
Common Bank of India home loan EMI mistakes
- Entering full property price instead of the sanctioned financed principal.
- Using an undated “BOI rate” from a blog instead of the rate on your quote.
- Choosing tenure only to minimise EMI, then underestimating 20–30 year interest.
- Skipping a +0.5% to +1% floating-rate stress test.
- Assuming Star Smart Home surplus set-off is already baked into this page’s EMI.
- Ignoring stamp duty, registration and insurance as separate cash needs.
- Treating eligibility capacity as the same as a budget you can sustain.
Tips before you finalise a Bank of India sanction
Try a slightly shorter tenure and note interest saved against the EMI rise. Keep EMI inside take-home pay after other obligations, then confirm with affordability, not only eligibility.
Ask whether the quoted rate is reducing-balance and RBLR-linked, whether Smart Home overdraft applies and how fees are deducted from disbursal. Confirm prepayment rules on the letter. For a bank-agnostic housing sketch, use the parent Home Loan EMI Calculator. Sibling provider pages: SBI, HDFC, ICICI, LIC and Axis Bank.
Important notes
Methodology: Reducing-balance EMI with monthly rate = annual % p.a. ÷ 12 ÷ 100 and tenure in months = years × 12. Schedule rows expand to monthly principal, interest and balance. Totals use round(emiRaw × n, 2); interest = total payment − principal; EMI displayed as round(emiRaw, 2). Same engine as the parent home loan EMI calculator.
Included: Financed principal, rate and tenure you enter.
Excluded by default: Processing fees, insurance, GST on fees, stamp duty, registration, penalties, floating-rate resets, Star Smart Home overdraft set-off, moratorium interest and foreclosure charges unless you fold them into the inputs yourself.

FAQs
EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1), with r = annual % p.a. ÷ 12 ÷ 100 and n = years × 12. This page uses reducing-balance maths, the same identity as the Home Loan EMI Calculator. Walkthrough: how EMI is calculated.
No. This is an independent Kalkulator.in tool that uses standard reducing-balance EMI maths with Bank of India–oriented examples and FAQs. Confirm final figures on your BOI sanction letter and amortisation schedule.
Enter the annual % p.a. on your quote or sanction letter. Do not rely on undated “current BOI rate” tables on third-party sites. Then stress +0.5% to +1% if the loan is floating / RBLR-linked.
Enter the financed principal Bank of India sanctions, not the full property price, if you pay a down payment in cash. Property price minus down payment (subject to LTV caps) is the usual loan input.
This tool allows up to 30 years, which matches common Bank of India housing tenure ceilings, subject to age at maturity and product rules on your sanction. Longer tenure lowers EMI and raises total interest.
No. The calculator assumes a level EMI at one rate for the tenure you enter. Star Smart Home–style surplus parking can reduce interest when funds sit in a linked overdraft account, but that daily set-off is not simulated here. Ask the branch how surplus balances change interest for your account.
Many floating-rate BOI housing loans for individual personal end-use do not charge a prepayment fee. Fixed-rate packages or non-individual structures can still attract a percentage fee, and some agreements set a waiting period after disbursal. Read your agreement. Extra principal paid early usually cuts interest; you often choose lower EMI or shorter tenure afterward.
Fees, insurance, day-count, floating resets, Smart Home set-off or a different principal (fee-loaded disbursal) can differ. This tool is indicative from the inputs you enter. Confirm against the sanction schedule.
After you know EMI, use the loan affordability calculator. Lender eligibility on the home loan eligibility calculator is not the same as a budget you can sustain. Check take-home with the salary calculator if needed.
Yes for a reducing-balance sketch. Enter the outstanding principal you plan to transfer (plus any top-up), the new rate and the remaining or fresh tenure on the takeover offer. Compare total interest against staying with the existing lender.
Many salaried and self-employed borrowers can claim relief on housing loan interest (and sometimes principal) under Indian tax rules, subject to limits, property use and documentation. Rules change; this calculator does not compute tax. Confirm with a qualified adviser or official Income Tax guidance for your case.
