Ask a question

What it is: A cash-versus-financing calculator that compares paying outright against borrowing, on both total cost and return on capital.
Who it is for: Buyers and investors with enough cash to choose, deciding where that cash does the most good.
The problem it solves: Cash avoids interest but consumes liquidity and lowers return on capital. The right answer depends on the rate, the alternative use of the money, and your tolerance for a payment.

The formula

Financing wins when (return on the cash you keep) > (after-tax cost of the loan)

Compare total interest paid against what the retained capital could earn elsewhere, then weigh liquidity, negotiating leverage and risk tolerance — which are decisions, not arithmetic.

How to use it

01
Price both paths
Total cash outlay and monthly obligation under each scenario.
02
Compute the cost of the loan
Total interest over your expected holding period, not the full term.
03
Compute the opportunity cost of cash
What the same money would earn in your next best use over that period.
04
Weigh the non-financial factors
Liquidity, offer strength, reserves and how a payment feels during a vacancy or a job change.

When to use it

Deciding whether to pay cash for an investment property.
Choosing between a larger down payment and keeping reserves.
Evaluating whether a cash offer's negotiating advantage is worth the liquidity.

Common mistakes

Comparing interest to nothing

Cash has an opportunity cost even when it sits idle. Compare against the real alternative, not against zero.

Using the full term

If you will sell or refinance in seven years, the interest you actually pay is seven years of it — not thirty.

Draining reserves for the negotiating edge

A stronger offer is not worth being unable to fix a roof.

Questions people ask

Should I pay cash for a rental property?

Cash maximizes cash flow and minimizes risk, but lowers return on capital and ties up liquidity. Finance when your capital reliably earns more than the loan costs, and you can carry the payment through a vacancy.

Does a cash offer really win?

Often yes, because it removes appraisal and financing contingencies and closes faster. Sellers frequently accept a lower cash offer for that certainty.

Can I finance later after buying with cash?

Yes — a delayed financing or cash-out refinance can recover much of the capital, subject to lender loan-to-value limits and seasoning rules.
