Your loan rate is 8.0% and investment return is 7.0%. Since your loan rate exceeds your investment return, paying cash is cheaper by €1577. The interest you pay outweighs what you'd earn investing. The breakeven investment rate is 1.3% — invest above this and the loan wins.

What Moves the Needle Most
How much each factor changes your Monthly Payment across its full range. Loan Term has the biggest impact.
Focus your attention on Loan Term — getting it right matters most. Factors lower down move the result less, so rough estimates there are fine.
Confidence & Assumptions
The outcome is fairly stable across best and worst cases — this is a robust decision.
Loan Net Cost: €24,598 (worst) → €22,181 (expected) → €19,516 (best)
These are the estimates the result depends on. Adjust them (and the Advanced inputs) to match your real situation — the closer they are to reality, the more reliable your decision.

How This Calculator Works
What this calculator does
This calculator compares two strategies: paying the full price in cash now, or taking a loan and investing the cash you would have spent. It reveals the true cost of each option.
How the calculation works
If you pay cash, you lose the investment returns that money could have earned. If you take a loan, you pay interest but can invest your cash. The calculator compares net costs including opportunity cost.
Formula
EMI = P × r × (1+r)^n / ((1+r)^n - 1) Total Loan Cost = EMI × n + Down Payment Net Loan Cost = Total Loan Cost - Down Payment × (1 + i/12)^(n) P = loan amount, r = monthly rate, n = months, i = investment return
Sources & defaults
- Standard amortising loan (EMI) formula
Opportunity cost = cash invested at your expected return
- Historical equity risk premium literature
Long-run stock/SIP defaults ~7–12% nominal before fees/tax — not a forecast
Example
€30,000 car, €6,000 down, 8% loan, 5 years, 7% investment: Loan costs €34,498 total. Investing the down payment earns €2,095. Net loan cost = €32,403 vs €30,000 cash. Cash is cheaper here.

Factors to Consider
- If investment return > loan rate, taking a loan can be better
- Investment returns are not guaranteed, loan interest is
- Liquidity matters — keeping cash available provides safety
- Tax deductions on loan interest can change the math
- Your risk tolerance determines whether to invest or pay cash
Common Mistakes
- Only comparing monthly payment vs upfront cost
- Forgetting that investment returns are uncertain
- Not including loan fees and insurance in the comparison
- Ignoring the risk of having less cash for emergencies
Frequently Asked Questions
When is taking a loan better than paying cash?+
When you can invest the cash at a higher after-tax return than the loan interest rate, and you are comfortable with investment risk.
What is opportunity cost?+
Opportunity cost is the return you give up by using money for one purpose instead of another. Paying cash means giving up potential investment returns.
Should I ever take a loan if I have the cash?+
It depends on your risk tolerance. If loan rate < investment return and you have an emergency fund, a loan can build more wealth. But it adds risk.
