Make room for what matters
Home Purchase Planner
Buying a home is two problems at once: saving the deposit, then servicing the loan. Enter today's asking price and when you plan to buy, and this planner sizes both halves at the assumptions you choose.

Anyone planning a purchase a few years out who wants both halves priced — the saving and the borrowing — rather than looking at the EMI alone. It is also a useful reality check on whether the timeline you have in mind is realistic.
Method
Inflated price, then deposit, then loan
Three existing calculations chained in order: the price is grown to the purchase date, the deposit is taken as a share of that future price, and the loan is priced on what remains using reducing-balance amortisation. Nothing about property markets is predicted — the growth rate is an input, and the answer should be read as 'if prices moved at this rate, here is what the deposit and the loan look like'.
Today's asking price is grown to your purchase date at the growth rate you set. That rate is an assumption you control, and setting it to zero is a perfectly reasonable way to plan against today's prices.
Your chosen deposit share is applied to that estimated future price, which gives the amount you need in cash on the day. The rest becomes the loan.
Your existing savings and monthly contribution are projected to the purchase date at the assumed return, and compared with the deposit. The gap, if any, is what has to change.
The loan is then priced on the remainder at the rate and tenure you set, using the same reducing-balance method as the home loan calculator. The instalment shown is the figure that calculator would give for that loan.
The total interest is shown because it is easy to overlook next to the instalment. On a twenty-year loan at typical Indian rates, interest often approaches the amount borrowed.
What this does not tell you
- Property prices are not predictable and this planner does not try. They vary by city, by locality and by project, and they can fall as well as rise. The growth rate is your assumption and the answer is sensitive to it.
- Stamp duty, registration, brokerage, GST on under-construction property, interiors and moving costs are all excluded, and lenders do not finance most of them. Depending on the state these can add 6-10% of the price to what you need in cash.
- Your actual loan rate is set by the lender, based on your credit profile and the rate cycle when you borrow. Most Indian home loans are floating-rate, so the instalment can change during the loan.
- Whether you would be approved for the loan is not assessed. Lenders limit the instalment as a share of income, so a plan that works arithmetically may still not be sanctioned.
- Tax deductions on home loan interest and principal are not modelled, and the rules differ between the old and new tax regimes.
- Renting versus buying is not compared. That comparison depends on rental yields, how long you would stay, and what the deposit would otherwise earn — a genuinely difficult question this page does not attempt.
