How to use this calculator

1. Enter today’s price for the car or the home down payment.
2. Set years to purchase, price inflation and expected return.
3. Read future cost and the SIP or lumpsum to have cash ready.

Formula and worked example

Future cost = today’s price × (1 + price inflation)^years. The required SIP is the amount whose step-up future value equals that cost at the expected return, and the lumpsum is its present value.

Future cost:  C = price today × (1 + price inflation)^Y
Monthly SIP:  C ÷ FV(a ₹1 step-up SIP over Y years at the expected return)
Lumpsum:      C ÷ (1 + r)^Y

Worked example. ₹50 L today · 7 years · 6% inflation · 10% return · no step-up → future cost ₹75.18 L, SIP ₹62,692/mo, or ₹38.58 L as a lumpsum today.

Assumptions and limits

• Price inflation default 6%; expected return default 10% (a shorter goal usually carries a lower-risk mix).
• Return constant; the SIP steps up each year if a step-up is set.
• Price inflation and investment return are separate assumptions.
• Does not include loan EMI for the balance amount—pair with the EMI calculator.
• Down-payment planning only unless you set the target to the full price.

Car down payment calculator

Car purchases often mix savings and a loan. Size the down payment first: a ₹50 lakh vehicle today becomes about ₹75.18 lakh in 7 years at 6% price inflation, needing roughly ₹62,692 monthly at 10% if you fund the full inflated price with a flat SIP. If you only need 20% down, scale the target first. Pair the residual loan with the EMI calculator so total outflow stays affordable. Write the car home goal inputs you trust into your annual review note so next year’s rerun of “Car down payment calculator” starts from recorded figures.

Car goal calculator

A car goal calculator is a dated savings plan for a depreciating asset—so honesty about timeline matters. The defaults push a ₹50 lakh today’s price to about ₹75.18 lakh after 7 years at 6%. Funding that entirely via SIP at 10% needs about ₹62,692 monthly. Many households should target a smaller car or a longer wait rather than stretch equity SIPs for a depreciating purchase. When household opinions differ on risk for car home goal under “Car goal calculator”, fund the more conservative case first and treat any extra debit as optional top-ups.

Home purchase goal calculator

Home down payments are larger and usually less flexible than car goals. Use today’s property price slice you intend to pay as equity, inflate it, then solve for SIP. Scaling the same maths as the ₹50 lakh / 7y example shows how fast property inflation lifts the target—about ₹75.18 lakh at 6%. Loan eligibility still depends on income and FOIR; this page does not underwrite a mortgage. Keep emergency reserves outside the down-payment folio. If the car home goal instalment for “Home purchase goal calculator” looks unaffordable, cut the target or add years before you inflate the assumed return unrealistically.
