Debt-to-Income Ratio Calculator
Your debt-to-income ratio, called FOIR by Indian lenders, is the share of your monthly income already committed to debt payments. This works it out on gross income and on take-home pay at the same time, because lenders use one and you live on the other, and the gap between them is wider than most people expect.
Salary before any deductions. Not CTC, which includes employer contributions you never receive.
Provident fund, professional tax and TDS. Used only to show the take-home comparison.
Housing
The EMI or mortgage payment you are applying for. Leave at 0 if you are not.
Other monthly obligations
The minimum due, not the outstanding balance. On a balance of 50,000 with a minimum of 2,500, the figure is 2,500.
Alimony, maintenance or any court-ordered payment. Groceries and utilities do not count.
FOIR on gross income
40.0%
- Same ratio on take-home
- 48.9%
- Front-end, housing only
- 23.3%
- Total monthly obligations
- ₹60,000
- Take-home left after obligations
- ₹62,800
Inside the range lenders call comfortable. Indian lender pages commonly describe below 40% as healthy.
| Measured against | Income used | Ratio |
|---|---|---|
| Gross income | ₹1,50,000 | 40.0% |
| Take-home pay | ₹1,22,800 | 48.9% |
Same obligations, same salary, 8.9% apart. Both figures are honest and they answer different questions. The EMI is paid from the lower one.
The thresholds above are lender and guarantor policy, and none of them is a regulation. The CFPB removed the 43% Qualified Mortgage limit in December 2020, and the Reserve Bank of India publishes no FOIR ceiling at all, leaving it to each bank's board.

Why does it show two ratios?
Because lenders measure against gross income and you repay from take-home pay, and in India the published guidance cannot agree which one FOIR means. The gap is not cosmetic.
Indian lender pages split roughly down the middle. IndusInd Bank, Bank of Baroda, Ujjivan and Godrej Capital use gross income. IIFL, Oolka and Fincover use take-home. At least two pages flip between the two inside a single article, one of them four times across five sentences. So the same borrower gets materially different answers depending which site they land on.
On a gross salary of Rs 1,50,000 with Rs 27,200 going out in provident fund, professional tax and withholding, Rs 60,000 of obligations reads as 40.0% against gross and 48.9% against take-home. Nine percentage points, no change to the borrower. One number sits mid-range for Indian lenders and the other sits near the ceiling several of them describe as a decline.
If you only know your CTC, the take-home calculator converts it, and gross versus net income explains what separates the three figures.
What are front-end and back-end ratios?
The front-end ratio counts housing costs alone against income, and the back-end ratio counts every monthly debt obligation including housing. US mortgage underwriting quotes them as a pair, usually 28/36 or 31/43.
Of the working tools surveyed for this build, one printed both numbers. Not one Indian tool showed the split at all, treating a home loan EMI as just another obligation in a single bucket. The distinction matters because the two ratios fail for different reasons: a high front-end means the house is too expensive, and a high back-end with a low front-end means everything else is.
Does current rent count?
Not when a new home loan payment is about to replace it, which is what the checkbox controls. A mortgage takes the place of the rent, so counting both would charge you twice for one roof.
This is the largest contradiction in the published guidance. Wells Fargo, NerdWallet and Rocket Mortgage all include rent in the numerator. Bank of America says not to. One Indian lender page treats rent as income. Only a single mortgage lender page states the reason the others leave implicit, which is that on a home loan application the new payment replaces the old one.
Untick the box and both amounts count, which is the right treatment when you are keeping the rental and borrowing for something else.
Where do the thresholds come from?
From lender and guarantor policy, and not from any regulator in either country. That is worth saying plainly, because most pages present these numbers as though a rulebook set them.
The US bands here are Fannie Mae's: 36% for manually underwritten loans, up to 45% where credit score and reserve requirements are met, and 50% for files run through Desktop Underwriter. The 43% figure that circulates as the mortgage limit was removed from the Qualified Mortgage rule by the CFPB in December 2020 and replaced with price-based thresholds.
The Indian bands are the ranges lenders publish about themselves, which is why they disagree so much. The Reserve Bank of India sets no FOIR ceiling at all, and its site search returns nothing for the term. What RBI regulates is the collateral, capping home loans at 80% of property value up to Rs 75 lakh and 75% above it.
What this calculator does not do
It does not tell you how much to borrow, and it cannot predict an approval. Lenders weigh credit history, employment stability, the property and their own portfolio position alongside any ratio, and two banks can decide the same file differently on the same day.
It does no tax arithmetic. The deductions figure is an input here, which is what the take-home calculator is for. It also treats every obligation as a flat monthly amount, so a loan ending in three months counts the same as one with twenty years to run, while a lender would look at the remaining tenure.
Pair this with the guide
Debt-to-Income Ratio and FOIR Explained goes through the primary rules behind every number here: what the CFPB actually changed in 2020, what Fannie Mae and FHA publish, and what RBI regulates instead of income. The calculator answers where you sit. The post explains who decided the lines and on what authority.
Frequently asked questions
Should I use gross income or take-home pay?
Lenders use gross, and your budget runs on take-home, which is why this calculator shows both. Every US page checked uses gross and says so. Indian lender pages split roughly evenly: IndusInd, Bank of Baroda, Ujjivan and Godrej Capital use gross, while IIFL, Oolka and Fincover use take-home, and at least two contradict themselves inside a single article. On a Rs 1,50,000 gross salary with Rs 27,200 of deductions, the same Rs 60,000 of obligations reads as 40.0% on gross and 48.9% on take-home. Both are honest. The EMI is paid from the lower one.
What is the difference between front-end and back-end ratio?
The front-end ratio counts only housing costs against income, and the back-end ratio counts every monthly debt obligation including housing. US mortgage underwriting uses both, and the pairing is usually written as 28/36 or 31/43. Of the working DTI tools surveyed in August 2026, one printed both numbers, and no Indian tool showed the split at all, treating a home loan EMI as just another obligation. This calculator reports both.
Does my current rent count if I am applying for a home loan?
No, when the new payment replaces it, which is what the checkbox controls. A mortgage or home loan EMI takes the place of the rent you are paying now, so counting both would charge you twice for one home. This is the single biggest contradiction in the published guidance: Wells Fargo, NerdWallet and Rocket Mortgage include rent, Bank of America says to leave it out, and one Indian page counts rent as income. Only one lender page states the reason, which is that the mortgage replaces the rent.
Do I enter my credit card balance or my minimum payment?
The minimum payment. A debt-to-income ratio compares monthly payments against monthly income, so a balance does not belong in it. On a balance of Rs 50,000 with a minimum due of Rs 2,500, the figure that belongs here is Rs 2,500. One Indian FOIR calculator surveyed asks for outstanding credit card debt and feeds it straight into the ratio, which inflates the answer by the whole ratio of balance to minimum payment.
Is 43% still the maximum DTI for a mortgage?
No. The CFPB's final rule of 10 December 2020 removed the General Qualified Mortgage 43 percent DTI limit and replaced it with price-based thresholds, with mandatory compliance from 1 October 2022. Lenders must still consider the ratio or residual income, and the CFPB's own consumer page on debt-to-income ratios publishes no threshold figure at all. The bands in this calculator come from Fannie Mae's selling guide, which is guarantor policy rather than regulation.
Does RBI set a maximum FOIR?
No. A search of the Reserve Bank of India's site returns zero records for FOIR, and the housing finance rules cover loan-to-value ratios and risk weights with no income test in them. RBI directs banks to frame their own board-approved lending norms. The Indian bands shown here are the ranges lender pages publish for themselves, which is why they vary so widely, from 40% to 75% depending on which page you read.
