Home Down Payment Calculator
A home loan never covers the whole price, and it does not cover stamp duty and registration at all for most homes. Enter the price, your down payment and when you plan to buy, and the calculator shows the cash you will need and the monthly SIP that gets you there.

A home costing ₹60,00,000 today could cost about ₹76,57,689 in 5 years at 5% a year, so you would need ₹19,90,999 in cash (20% down payment plus 6% stamp duty and registration). At an assumed 10% return that takes a monthly SIP of ₹15,186, or ₹7,36,254 invested once today.
Under RBI norms banks lend at most 75% to 90% of the property value, depending on loan size, so 10% to 25% is the usual minimum.

Varies by state, and some states charge women buyers less. Check your state's current rate.
An assumption. For a purchase a few years away, a lower-risk mix is common.

- What it is:
- A savings planner for the cash part of buying a home in India.
- What it calculates:
- The future price, the down payment plus stamp duty and registration, the home loan needed and the monthly SIP or lumpsum to save the cash.
Key Assumptions
- Property prices and your investments grow at constant rates you choose.
- Stamp duty and registration are a flat percentage of the price; real state rules can have slabs and concessions.
- Other costs such as brokerage, legal fees, GST on under-construction homes, interiors and loan processing fees are not included.
- SIP instalments are invested at the start of each month at the annual return divided by 12.
How does the Home Down Payment Calculator work?
The property price is grown at the price growth you enter, compounded once a year, to the year you plan to buy. Property prices vary widely by city and locality, so this is an assumption to test, not a forecast.
The cash you need is the down payment plus stamp duty and registration, both taken as a percentage of that future price. Stamp duty and registration are set by each state and differ between states and sometimes between buyers, so the 6% default is a placeholder: check your state's current rate.
The home loan is the price minus the down payment. RBI caps how much of a home's value a bank may lend: up to 90% for loans up to ₹30 lakh, 80% for loans above ₹30 lakh up to ₹75 lakh, and 75% above ₹75 lakh. If your planned loan is above the cap for its size, the calculator flags it.
Savings already set aside are grown at the expected return and subtracted. The monthly SIP for the rest is solved with the same start-of-month convention as our SIP calculator and rounded up to the next rupee, and the lumpsum alternative is the gap discounted back to today.
Home Down Payment Calculator formula
Cash = P x (1 + g)^t x (d + s); SIP = (Cash - S x (1 + r)^t) / ([((1 + i)^n - 1) / i] x (1 + i))
- P
- = property price today
- g
- = property price growth per year, as a decimal
- t
- = years until you buy
- d
- = down payment as a share of the price
- s
- = stamp duty and registration as a share of the price
- S
- = savings already set aside
- r
- = expected annual return, as a decimal
- i
- = monthly return = annual return / 12 / 100
- n
- = number of monthly instalments = t x 12
Home loan needed = P x (1 + g)^t x (1 - d). It is compared with the RBI loan-to-value ceiling for its size.
