Real Estate Flip Calculator

A real estate flip involves purchasing an under-construction property, holding it through the build period, and selling it before or shortly after possession — capturing the appreciation between booking price and market price at delivery.

This calculator models the complete cash economics of such a deal: your loan disbursements across multiple project tranches, the interest cost under either a Pre-EMI or Full EMI structure, how much principal you repay before the sale, and ultimately whether the net profit justifies the capital deployed and the illiquidity risk taken.

Pre-EMI — You pay only interest on the disbursed loan amount during construction. Full EMI (principal + interest) begins only after the final tranche is disbursed and the property is ready. Interest outflow is lower initially, but you carry the full principal into Phase 2.

Full EMI — Each tranche starts its own EMI schedule immediately upon disbursement, with all tranches sharing a common loan end date. You repay more principal during the holding period, so the remaining loan balance at sale is lower — but total monthly outflow is higher from the start.

For a short flip (sell before completion), Pre-EMI usually results in lower total outflow. For a longer hold, Full EMI reduces the outstanding balance faster and may leave more in your pocket on sale.

Under-construction properties are typically funded in stages (tranches) as construction milestones are reached — foundation, slab, fit-out, etc. The loan is released by the bank in corresponding tranches rather than as a lump sum.

In this calculator, you can add as many tranches as your project requires. The first tranche is always at month 0 (booking date). Each subsequent tranche specifies what percentage of the loan is released and in which month. The disbursement amount in rupees is shown below each percentage so you can verify the figures match your builder's payment schedule. For Pre-EMI, only interest on the disbursed amount is charged until all tranches are released; for Full EMI, each tranche immediately begins its own reducing-balance repayment.

The calculator first computes your total ROI on cash outflow: (Net Profit ÷ Total Cash Outflow) × 100. This is then converted to an annualised figure using the compound annualisation formula:

Annualised ROI = ((1 + ROI/100)^(12/holdingMonths) − 1) × 100

This makes the return comparable across different holding periods — a 30% return over 36 months is roughly 9.1% p.a., while the same 30% over 24 months is ~14.1% p.a. The verdict benchmarks your annualised ROI against FD rates (~7% p.a.) and equity index returns (~12% p.a.).

Quicklend specialises in asset-backed lending. If you hold mutual funds, you can use a Loan Against Mutual Funds (LAMF) to fund your down payment or bridge short-term cash flow gaps during the construction phase — without liquidating your investments and forgoing their returns.

This can be especially useful when a tranche payment falls due but liquidity is tight. Your portfolio keeps compounding while Quicklend covers the immediate cash need at competitive rates.
