Should I get a car loan before shopping for a car?
You have a good start (estimated max amount you will pay, estimated max down payment, and term) Now go to your bank/credit union and apply for the loan. Get a commitment. They will give you a letter, you may have to ask for it. The letter will say the maximum amount you can pay for the car. This max includes their money and your down payment. The dealer doesn't have to know how much is loan. You also know from the loan commitment exactly how much your monthly payment will be in the worst case. If you have a car you want to trade in, get an written estimate that is good for a week or so. This lets you know how much you can get from selling the car. Now visit the dealer and tell them you don't need a loan, and won't be trading in a car. Don't show them the letter. After all the details of the purchase are concluded, including any rebates and specials, then bring up financing and trade-in. If they can't beat  the deal from your bank and the written estimate for the car you are selling, then the deal is done. Now show them the letter and discuss how much down they need today. Then go to the bank for the rest of the money. If they do have a better loan deal or trade in then go with the dealer offer, and keep the letter in your pocket. If you go to the dealer first they will confuse you because they will see the price, interest rate, length of loan, and trade in as one big ball of mud. They will pick the settings that make you happy enough, yet still make them the most money. Yes, you are correct to go to the credit union first. Get approved for a loan first. Often, upon approval, the credit union will give you a blank check good for any amount up to the limit of the loan. When you buy the car, make it payable to the dealer, write in the amount and sign it. Enjoy the new car!
"By the sounds of things, you're not asking for a single formula but how to do the analysis... And for the record you're focusing on the wrong thing. You should be focusing on how much it costs to own your car during that time period, not your total equity.  Formulas:  I'm not sure how well you understand the nuts and bolts of the finance behind your question, (you may just be a pro and really want a consolidated equation to do this in one go.) So at the risk of over-specifying, I'll err on the side of starting at the very beginning. Any financial loan analysis is built on 5 items: (1) # of periods, (2) Present Value, (3) Future Value, (4) Payments, and (5) interest rate.  These are usually referred to in spreadsheet software as NPER, PV, FV, PMT, and Rate. Each one has its own Excel/google docs function where you can calculate one as a function of the other 4. I'll use those going forward and spare you the 'real math' equations.  Layout: If I were trying to solve your problem I would start by setting up the spreadsheet  up with column A as ""Period"". I would put this label in cell A2 and then starting from cell A3 as ""0"" and going to ""N"". 5 year loans will give you the highest purchase value w lowest payments, so n=60 months... but you also said 48 months so do whatever you want.  Then I would set up two tables side-by-side with 7 columns each. (Yes, seven.) Starting in C2, label the cells/columns as: ""Rate"", ""Car Value"", ""Loan Balance"", ""Payment"", ""Paid to Interest"", ""Principal"", and ""Accumulated Equity"". Then select and copy cells C2:I2 as the next set of column headers beginning in K2. (I usually skip a column to leave space because I'm OCD like that :) ) Numbers: Now you need to set up your initial set of numbers for each table. We'll do the older car in the left hand table and the newer one on the right. Let's say your rate is 5% APR. Put that in cell C1 (not C3). Then in cell C3 type =C$1/12. Car Value $12,000 in Cell D3. Then type ""Down Payment"" in cell E1 and put 10% in cell D1. And last, in cell E3 put the formula =D3*(1-D$1). This should leave you with a value for the first month in the Rate, Car Value, and Loan Balance columns. Now select C1:E3 and paste those to the right hand table. The only thing you will need to change is the ""Car Value"" to $20,000. As a check, you should have .0042 / 12,000 / 10,800 on the left and then .0042 / 20,000 / 18,000 on the right.  Formulas again: This is where spreadsheets become amazing. If we set up the right formulas, you can copy and paste them and do this very complicated analysis very quickly.  Payment The excel formula for Payment is =PMT(Rate, NPER, PV, FV). FV is usually zero. So in cell F3, type the formula =PMT(C3, 60, E3, 0). Obviously if you're really doing a 48 month (4 year) loan then you'll need to change the 60 to 48. You should be able to copy the result from cell F3 to N3 and the formula will update itself.  For the 60 months, I'm showing the 12K car/10.8K loan has a pmt of $203.81. The 20K/18K loan has a pmt of 339.68.  Interest The easiest way to calculate the interest is as =E3*C3. That's (Outstanding Loan Balance) x (Periodic Interest Rate). Put this in cell G4, since you don't actually owe any interest at Period 0.  Principal If you pay PMT each month and X goes to interest, then the amount to principal is ""PMT - X"". So in H4 type =-F3 - G3. The 'minus' in front of F3 is because excel's PMT function returns a negative amount. If you want to, feel free to type ""=-PMT(...)"" for the formula that's actually in F3. It's your call.  I get 159 for the amount to principal in period 1.  Accumulated Equity As I mentioned in the comment, your ""Equity"" comes from your initial Loan-to-Value and the accumulated principal payments. So the formula in this cell should reflect that. There are a variety of ways to do this... the easiest is just to compare your car's expected value to your loan balance every time. In cell I3, type =(D3-E3). That's your initial equity in the car before making any payments. Copy that cell and paste it to I4. You'll see it updates to =(D4-E3) automatically. (Right now that is zero... those cells are empty, but we're getting there) The important thing is that as JB King pointed out, your equity is a function of accumulated principal AND equity, which depreciates. This approach handles those both.  Finishing up the copy-and-paste formulas I know this is long, but we're almost done.  Rate // Period 1 In cell C4 type =C3.  Payment // Period 1 In cell F4 type =F3.  Loan Balance // Period 1 In cell E4 type =E3-H4. Your loan balance at the end of period is reduced by the principal you paid. I get 10,641.  Car Value // Period 1 This will vary depending on how you want to handle depreciation. If you ignore it, you're making a major error and it's not worth doing this entire analysis...  just buy the prettiest car and move on with life. But you also don't have to get it scientifically accurate. Go to someplace like edmunds.com and look up a ballpark. I'm using 4% depreciation per year for the old (12K) car and 7% for the newer car. However, I pulled those out of my ass so figure out what's a better ballpark.  In G1 type ""Depreciation"" and then put 4% in H1. In O1 type ""Depreciation"" and then 7% in P1. Now, in cell D4, put the formula =D3 * (1-(H$1/12)).  Paste formulas to flesh out table As a check, your row 4 should read 1 / .0042 / 11,960 / 10,641 / 203.81 / 45 / 159 / 1,319. If so, you're great. Copy cells C4:I4 and paste them into K4:Q4.  These will update to be .0042 / 19,883 / 17,735 / 339.68 / 75 / 265 / 2,148.  If you've got that, then copy C4:Q4 and paste it to C5:C63. You've built a full amortization table for your two hypothetical loans. Congratulations.  Making your decision I'm not going to tell you what to decide, but I'll give you a better idea of what to look at. I would personally make the decision based on total cost to own during that time period, plus a bit of ""x-factor"" for which car I really liked.  Look at Period 24, in columns I and Q. These are your 'equities' in each car. If you built the sheet using my made-up numbers, then you get ""Old Car Equity"" as 4,276. ""New Car Equity"" is 6,046. If you're only looking at most equity, you might make a poor financial decision.  The real value you should consider is the cost to own the car (not necessarily operate it) during that time... Total Cost = (Ending Equity) - (Payment x 24) - (Upfront Cash).  For your 'old' car, that's (4,276) - (203.81 * 24) - (1,200) = -1,815.75 For the 'new' car, that's (6,046) - (339.68 * 24) - (2,000) = -4,106.07.  Is one good or bad? Up to you to decide. There are excel formulas like ""CUMPRINC"" that can consolidate some of the table mechanics, but I assumed that if you're here asking you would have gotten stuck running some of those.  Here's the spreadsheet: https://docs.google.com/spreadsheet/ccc?key=0Ah0weE0QX65vdHpCNVpwUzlfYjlTY2VrNllXOS1CWUE#gid=1" I think you are a little confused. If you have 10.000€ in cash for a car, but you decide instead to invest that money and take out a loan for the car at 2,75% interest, you would have to withdraw/sell 178€ each month from your investment to make your loan payment. If you made exactly 2,75% on your investment, you would be left with 0€ in your investment when the loan was paid off.  If your investment did better than 2,75%, you would come out ahead, and if your investment did worse than 2,75%, you would have lost money on your decision. Having said all that, I don't recommend borrowing money to buy a car, especially if you have that amount of cash set aside for the car.  Here are some of the reasons: Sometimes people feel better about spending large amounts of money if they can pay it off over time, rather than spending it all at once.  They tell themselves that they will come out ahead with their investments, or they will be earning more later, or some other story to make themselves feel better about overspending.  If getting the loan is allowing you to spend more money on a car than you would spend if you were paying cash, then you will not come out ahead by investing; you would be better off to spend a smaller amount of money now. I don't know where you are in the world, but where I come from, you cannot get a guaranteed investment that pays 2,75%.  So there will be risk involved; if the next year is a bad one for your investment, then your investment losses combined with your withdrawals for your car payments could empty your investment before the car is paid off.  Conversely, by skipping the 2,75% loan and paying cash for your car, you have essentially made a guaranteed 2,75% on this money, comparatively speaking. I don't know what the going rate is for car loans where you are, but often car dealers will give you a low loan rate in exchange for a higher sales price.  As a result, you might think that you can easily invest and beat the loan rate, but it is a false comparison because you overpaid for the car. An auto title loans are typically utilized by those that wish to obtain a funding with bad credit rating or no credit in any way. An auto-mobile title lending frequently called a vehicle title lending or merely title funding as well as pink slip funding’s. You merely should have a vehicle that is paid off or nearly paid off and also you could make use of the auto title as security to obtain the cash money you require, enabling you to continue driving your vehicle while paying your loan.

They are very likely to offer better loan rate than the dealer. Because you start there you have a data point so you can tell if the dealer is giving you a good rate.  Having the loan approved before going to the dealer allows you to negotiate the best deal for the purchase price for the car. When you are negotiating price, length of loan, down payment, and trade in it can get very confusing to determine if the deal is a good one. Sometimes you can also get a bigger rebate or discount because to the dealer you are paying cash. The general advice is that a lease for the average consumer is a bad deal. You are paying for the most expensive months, and at the end of the lease you don't have a car. With a loan you keep the car after you are done paying for it. Another reason to avoid the lease. It allows you to purchase a car that is two or three years old. These are the ones that just came off lease. I am not a car dealer, and I have never needed a work visa, but I think their concern is that there is a greater risk of you not being in the country for the entire period of the lease. Either approach will put a strain on your friendship, unless you are willing to treat it as a gift which may or may not be returned rather than a loan. I agree that paying it direct to the dealer (or giving her a check that is made out to the dealer) avoids the risk of the money getting sidetracked. Your practice of waiting until you can pay cash is a good one. It will certainly prevent you from getting into debt! Now, to be clear, your question puts a credit card in the same category as a loan, but it doesn't have to be. You could use a credit card almost like cash, if you are careful. I'm not familiar with the system in France, but in the US, even if you are paying cash all the time, there are some benefits to getting a credit card and paying it off in full every month, instead of simply paying with cash. Some of those benefits are: One pretty big downside of having a credit card depends on your personality. Some people, once they have credit, end up spending beyond their means, and end up getting into debt. Please look into whether credit cards work the same way in France before considering the above advice. As for your question regarding getting a loan vs paying cash, that will usually be personal preference, since with a loan you can buy expensive items (such as a house or car) much sooner than you otherwise could if you waited until you saved the money. For example, it might take 10 years or more to build up enough money to purchase a house with cash, so if you don't want to wait that long, you'll need to finance it. "Repayment of student loans is usually deferred until graduation. Unless you are late or non-performing on a loan, it will make no difference to an auto loan. To get a (normal) auto loan you will need to demonstrate a source of income or have the loan co-signed by someone who does have income. As a general rule of thumb, banks care a lot more about your income than your ""credit score""." "Without knowing the details of your financial situation, I can only offer general advice.  It might be worth having a financial counselor look at your finances and offer some custom advice.  You might be able to find someone that will do this for free by asking at your local church. I would advise you not to try to get another loan, and certainly not to start charging things to a credit card.  You are correct when you called it a ""nightmare.""  You are currently struggling with your finances, and getting further into debt will not help.  It would only be a very short-term fix and have long-lasting consequences.   What you need to do is look at the income that you have and prioritize your spending.  For example, your list of basic needs includes: If you have other things that you are spending money on, such as medical debt or other old debt that you are trying to pay off, those are not as important as funding your basic needs above. If there is anything you can do to reduce the cost of the basic needs, do it.  For example, finding a cheaper place to live or a place closer to your job might save you money.  Perhaps accepting nutrition assistance from a local food bank or the Salvation Army is an option for you. Now, about your car: Your transportation to your job is very much one of your basic needs, as it will enable you to pay for your other needs.  If you can use public transportation until you can get a working car again, or you can find someone that will give you a ride, that will solve this problem.  If not, you'll need to get a working car. You definitely don't want to take out another loan for a car, as you are already having trouble paying the first loan.  I'm guessing that it will be less expensive to get the engine repaired than it will be to buy a new car at this point.  But that is just a guess.  You'll need to find out how much it will cost to fix the car, and see if you can swing it by perhaps eliminating expenses that aren't necessary, even for a short time.  For example, if you are paying installments on medical debt, you might have to skip a payment to fix your car.  It's not ideal, but if you are short on cash, it is a better option than losing your job or taking out even more debt for your car. Alternatively, buying another, functional car, if it costs less than fixing your current car, is an option.  If you don't have the money to pay your current car loan payments, you'll lose your current car. Just to be clear, many of these options will mess up your credit score.  However, borrowing more, in an attempt to save your credit score, will probably only put off the inevitable, as it will make paying everything off that much harder.  If you don't have enough income to pay your debts, you might be better off to just take the credit score ding, get back on your feet, and then work to eliminate the debt once you've got your basic needs covered. Sorry to hear about your situation.  Again, this advice is just general, and might not all apply to your financial details.  I recommend talking to the pastor of a local church and see if they have someone that can sit down with you and discuss your options."
