Finance
Affordability calculator
This runs backwards from the instalment: what you can commit each month, less what you already owe, becomes the instalment available; the instalment becomes the loan it would support; the loan becomes an indicative price once your own lender has told you what share it will fund. Every ratio in that chain is a policy decision made by somebody reading your file, so every one of them is a box you fill in — and the answer is arithmetic on your assumptions, not an eligibility.
Start with the month, not the price
Net of tax, as it reaches your account.
Instalments on other borrowings. Leave blank if none.
A lender's own ceiling on this is policy. We publish none.
The rate, the tenure and the funded share follow in the full panel below. Nothing you type leaves the browser.
The method
From an instalment you can carry to a price
Four steps, in the order the arithmetic runs.
The arithmetic runs backwards from the instalment. First, how much of your monthly income you are prepared to commit, less what you already owe each month on other borrowings. That difference is the instalment available.
An instalment supports a loan whose size depends only on the rate and the tenure: reverse the instalment formula and you get the principal that instalment would clear. A longer tenure supports a larger loan at the same instalment, and costs more interest to do it.
The loan is not the price. The rest is yours to find, and it arrives earlier than most buyers plan for — the shortfall between the loan and the price, plus registration and taxes on top, all before possession.
Every ratio on this page is one you enter. The share of income you commit and the share of price your lender will fund are both policy decisions, made by a lender reading your file, and we will not put a number in either box on your behalf.
The caveat that outranks the answer
A lender's policy overrides everything on this page
Not a disclaimer. The one fact that governs how far the output can be trusted.
Two lenders reading the same file reach different answers, and the difference is not arithmetic — it is policy. What counts as income, whether variable pay is discounted and by how much, which existing obligations are counted against you, how a co-applicant’s income is treated, what share of the price will be funded against this particular property, and what the credit assessment does to the rate you are offered are all internal, all unpublished, and all capable of moving the number on this page by a wide margin in either direction.
Which is why nothing here is filled in for you. Use the figure to decide what to ask a lender for. Do not use it to decide what to offer a seller, and do not show it to one as evidence of anything.
The empty box
Why we ask you for the rate
We ask you for the rate rather than filling one in, and the reason is not caution. No published rate stays current: lenders reprice floating loans against an external benchmark that moves, the figure in an advertisement is the best case for the strongest applicant, and your own rate is set only after your file is assessed. A number typed into a page that is built once and served for months would be wrong within weeks and would look authoritative the entire time. So the page holds no rate, and the answer you get is an answer to the assumption you supplied.
Your figures
Run it on your own numbers
Six inputs. Every one of them yours, including the two ratios.
Income, obligations, and the two ratios
Enter monthly figures. The share of income and the funded share are the two ratios a lender sets; enter what your own lender has told you, or a figure you are comfortable committing to.
Net of tax, as it reaches your account.
Instalments on other borrowings. Leave blank if none.

Limits
What the figure is not
Three statements, and the first one is the reason this page exists.
Read alongside the answer
- A lender's own policy overrides every figure here. It decides what counts as income, which obligations count against you, how a co-applicant is treated, how variable pay is discounted, and what share of the price it will fund on this particular property. None of that is arithmetic and none of it is visible from outside.
- This is not an eligibility, a pre-approval or an in-principle sanction, and nothing on this page should be shown to a seller as evidence of one.
- The figure ignores what the home costs after you own it — maintenance, property tax, insurance, and the repairs a new household discovers. An instalment that consumes the last rupee of the available share is a plan with no room in it.
Beyond arithmetic
Three things no calculator can know
Your lender's policy
How much of your income a lender will let you commit, what it counts as income, which of your existing obligations it counts, what share of the price it will lend against, and what it does with a co-applicant are all internal policy. Two lenders reading the same file reach different answers, and neither answer is arithmetic.
Your credit assessment
The rate you are offered is set after your file is assessed — bureau record, employment, existing exposure, the property itself. A rate quoted in an advertisement is the best case for the strongest applicant, and a page that assumed it would be quietly wrong for almost everyone.
The rate on the day you sign
Floating rates reprice against an external benchmark, and the benchmark moves. Any schedule computed today is a picture of one assumption held flat for the whole tenure, which is the one thing a floating rate never does.
Questions
Questions this page is asked
- Is this an eligibility check?
- No. It is arithmetic on assumptions you supplied. A lender's own policy overrides all of it — what it counts as income, which obligations it counts, how it treats a co-applicant, and what share of the price it will fund on that specific property.
- Why do you not fill in the share of income I can commit?
- Because that share is a lender's policy and a household's judgement, not a constant. Two lenders reading the same file allow different amounts, and neither figure is one we could publish honestly.
- What does the calculation leave out?
- Everything that is not the instalment: registration and taxes at purchase, maintenance, property tax, insurance, and the running cost of the home. A plan that commits the last available rupee to the instalment has no room in it.

Where to go from here
These tools are meant to be used together — an instalment is only half a decision until you have seen what the schedule, the plan and the paperwork do to it.
Take the question to a lender, not to a seller
The only figure that binds is the one in a sanction letter. Get that first, in writing, and every conversation afterwards is about a home rather than about a number.
