How to save for a big purchase like a car or a house

To save for a big purchase, work out its full price and the date you need it, then divide to get a monthly amount. Keep that money in a deposit or account that cannot fall in value before the date. Decide early how much of it, if any, you will borrow.

Key takeaways

  • The monthly amount is what you still need divided by the months left, so a fixed date turns a vague wish into a number.
  • In one worked example, ₹8,000 a month for 24 months in an RD at 6.40% reaches about ₹2,05,266 on the calculator's method. The rate is SBI's card in force since 15 December 2025.
  • RBI's directions as updated on 1 October 2026 cap a bank or housing finance company at 90%, 80% or 75% of a home's value. The cap depends on loan size, so the down payment is at least 10%, 20% or 25%.
  • On an assumed ₹6,00,000 loan at 9%, five years costs ₹1,47,300 in interest and three years ₹86,880. The shorter loan has a higher EMI.
  • A floating-rate loan taken by an individual for a non-business purpose can be prepaid without any charge, however old the loan is.

To save for a big purchase, put a full price and a date on it and divide to get a monthly amount. Keep the money somewhere that fits the time left. Then decide early how much of the price, if any, a loan will cover. The same method works for a phone, a car, a wedding or the down payment on a flat.

The down payment is the part of the price you pay from your own savings. A loan covers the rest.

How do you save for a big purchase?

Work through five short steps, in this order.

  1. Price it fully. Add what you pay on the day, not only the sticker price.
  2. Set the date. The number of months you have decides everything that follows.
  3. Work out the monthly amount. Divide what you still need by the months left.
  4. Pick where the money waits. A purchase one to five years away needs a place where the money cannot fall in value just before you spend it.
  5. Decide how much to borrow, if anything. A loan shrinks the amount to save, but it adds interest.

One thing comes before all five. Money set aside for emergencies and any expensive debt you carry both come first. Where to keep your emergency savings puts the emergency amount at three to six months of expenses. The steps in what to do about a debt trap cover the debt side.

How do you work out the full price of what you want to buy?

Add everything you pay at purchase, not only the price on the tag.

For a car, the figure to use is the on-road price. That is the price of the car plus registration, insurance and other charges at purchase. Then count what the car costs each month after you own it: fuel, servicing, parking and the EMI if you borrow. An EMI, or equated monthly instalment, is the fixed amount you pay each month that covers interest and part of the loan.

For a house, the price on the agreement is only part of it. Stamp duty and registration come on top, along with moving-in costs. Additional charges when buying a house takes those apart.

So the answer to "how much should I have saved before buying a car" is not a fixed rule. It is the down payment you choose, plus the charges due on purchase day. The loan covers the rest, and you can work out its interest on a car loan calculator.

How much do you need to save each month?

Divide what you still need by the number of months left. For "how long will it take", turn it around: months equal the target divided by the monthly amount.

Take Arjun, 31, a sales manager in Coimbatore. He wants a car in two years. He assumes an on-road price of ₹8,00,000 (assumed, not a quote). He plans a ₹2,00,000 down payment and a loan for the rest.

With no interest at all, ₹2,00,000 divided by 24 months is ₹8,333.33, so ₹8,334 a month.

Now say he puts the money in a recurring deposit (RD). That is a deposit where you pay in a fixed amount every month for a set period. SBI's card in force since 15 December 2025 gives 6.40% for term deposits of 2 years to less than 3 years. Its RD page, last updated on 30 April 2026, says RD interest follows the term deposit rates. Rates change, so check the bank's own page on the day.

At 6.40%, the recurring deposit calculator shows ₹8,000 a month for 24 months growing to ₹2,05,266, of which ₹1,92,000 is what he paid in. That is the calculator's method, not SBI's own maturity figure. The interest is added to his income and taxed at his slab rate, the tax rate for his income band. So about ₹8,000 a month reaches the target. What is a recurring deposit explains how an RD works.

How much should you save for a house down payment?

A bank or housing finance company can lend only a set share of a property's value, and the rest is your down payment. RBI caps the share. Its directions, as updated on 1 October 2026, set the limits for banks and housing finance companies. They can lend up to 90% on a loan of ₹30 lakh or less. The cap is 80% on a loan above ₹30 lakh up to ₹75 lakh, and 75% above ₹75 lakh.

That makes the smallest down payment 10%, 20% or 25% of the price, depending on the loan size. Stamp duty and registration do not count as part of the price for this, unless the home costs ₹10 lakh or less. You pay them on top of your down payment.

Here is an example. A couple in Hyderabad want to buy a ₹52,00,000 flat in five years. The loan would fall in the ₹30 lakh to ₹75 lakh band, so it can be at most 80%, which is ₹41,60,000. At least ₹10,40,000 must come from their savings, plus stamp duty and registration.

Spread over five years, that is ₹10,40,000 divided by 60 months, or ₹17,334 a month before any interest. These are labelled figures for one example, not a target for anyone else.

Other pages cover what sits around the saving. Signs you're ready to buy a house deals with readiness, and is buying a house really an investment with buying versus renting. The home loan calculator shows what the loan side looks like.

Where should you keep money for a purchase one to five years away?

Keep it somewhere it cannot fall in value just before you need it. That points to a bank deposit for the term rather than shares.

A bank RD or fixed deposit (FD) fits. An FD is money placed with a bank for a set period at a rate fixed when you open it. SBI's RD runs from 12 months to 120 months, and its minimum is ₹100 a month, on a page last updated on 30 April 2026. A post office RD runs five years from ₹100 a month. You can close it after three years, but then you get only the savings account rate (4%) for the whole period.

If plans change, a deposit can be broken. At a commercial bank or small finance bank, an individual's term deposit of ₹1 crore or less can be withdrawn early. The interest is paid at the rate for the period the money actually stayed. SBI's RD page cuts the interest rate by 0.50% on early closure when the amount paid in is up to ₹5 lakh.

Bank deposits are insured by DICGC, the RBI-owned body that insures bank deposits, up to ₹5,00,000 per depositor per bank, principal and interest together.

Shares do not suit money needed soon. Their values can be well below cost for months. A purchase date does not move because the market is down. The comparison across other options sits in looking to invest for the short term. The fixed deposit calculator helps with the deposit side.

Should you save up or take a loan for a big purchase?

Saving costs you time, and borrowing costs you interest. Which one costs more depends on your own numbers.

Back to Arjun. Say he borrows ₹6,00,000 for the car at an assumed 9% a year (an assumed rate, not a quote). The table shows what the loan term changes.

Loan termEMITotal interest
5 years₹12,455₹1,47,300
3 years₹19,080₹86,880

The longer loan has the lower EMI but costs ₹60,420 more in interest. A shorter loan or a bigger down payment cuts the interest. The EMI is higher on the shorter term. What are EMIs and how do they work explains how the figures are worked out.

Early repayment matters too. A floating rate is an interest rate that can change during the loan. Suppose your loan is floating-rate and you took it as an individual for a purpose other than business. Then the lender cannot charge you for prepaying it. That holds for part or full prepayment, from any source of money, at any time, however old the loan is.

A fixed-rate loan is different. In RBI's terms that means a rate fixed for the whole term. The lender may charge what its policy and your loan papers say, worked out on the amount you prepay. The charge sits in the sanction letter, the loan agreement and the Key Facts Statement. Check which kind of rate you have before assuming either. For home loans specifically, see prepay your home loan or invest.

How do you stay on track until the purchase date?

Make the saving automatic and check it once a month. Set up a separate account for the goal and an auto-debit on salary day, so the money moves before you can spend it. Ten ways to save money from your salary goes into salary-day saving.

Send raises and bonuses to the goal. Mark milestones, such as a quarter of the target. The 50-30-20 rule is a budgeting rule of thumb, not a regulation, if you want a starting point for the monthly budget.

If a month goes wrong, move the date or lower the target. Do not dip into emergency money. The goal can wait a month, and an emergency cannot.

Frequently asked questions

How do you save for a big purchase?
To save for a big purchase, work out its full price and the date you need it, then divide to get a monthly amount. Add the charges due on purchase day, not only the sticker price. Keep the money where it cannot fall in value before the date, and decide early how much you will borrow.
How much should I save before buying a car?
No rule sets a figure. It is the down payment you choose plus the charges due on purchase day, such as registration and insurance. A loan covers the rest. In the worked example, Arjun assumes an on-road price of ₹8,00,000, plans a ₹2,00,000 down payment and borrows ₹6,00,000.
How much down payment do I need for a house?
At a bank or housing finance company, it is at least 10%, 20% or 25% of the price, depending on loan size. RBI's directions as updated on 1 October 2026 allow 90% on loans up to ₹30 lakh, 80% up to ₹75 lakh and 75% above. Stamp duty and registration come on top, unless the home costs ₹10 lakh or less.
Where should I keep money for a car I plan to buy in two years?
A bank RD or FD for the term fits money needed on a fixed date. SBI's card in force since 15 December 2025 gave 6.40% on 2 years to under 3 years, and rates change. Bank deposits are insured by DICGC up to ₹5,00,000 per depositor per bank. Shares can sit below cost for months.
Is it better to save for a car or take a car loan?
Saving costs time and borrowing costs interest. On an assumed ₹6,00,000 loan at 9% a year, five years means ₹12,455 a month and ₹1,47,300 interest, while three years means ₹19,080 and ₹86,880. A bigger down payment shrinks the loan and its interest.
How can I save for a trip six months away?
Use the same method: price the whole trip, divide by six months and keep the money where it will not fall in value. A savings account or a short bank deposit works for a short wait.
Should I use my emergency fund for a down payment?
No. Where to keep your emergency savings puts the emergency amount at three to six months of expenses, and that money stays separate from your goal. Save for the purchase in its own account. If a month falls short, move the date or lower the target instead.
