Should I pay off my mortgage, begin retirement savings, or build my emergency fund?
"Welcome to Money.SE. I will say upfront, Personal Finance is just that, personal, and you are likely to get multiple, perhaps conflicting, answers. Are you sure the PMI will drop off after 2 years? The rules are specific, and for PMI, when prepayments put you at that 78/80% LTV, your bank can require an appraisal, not automatically drop it. Talk to the banks, get confirmation, and depending what they say, keep hacking away at the mortgage.  After this, I suggest jumping on Roth IRAs. You are in the 15% bracket, and the Roth will let you deposit $5500 for each you and your wife. A great way to kickstart a higher level of retirement savings.  After this, I'm not comfortable with the emergency savings level. If you lose your job tomorrow (Funny story, my wife and I lost our's on the same day 3 years ago) and don't have enough savings (Our retirement accounts were good to just retire that day) you can easily run out of money and be late on the mortgage. It's great to prepay the mortgage to get rid of that PMI, but once there, I'd do the Roth and then focus on savings. 6 months expenses minimum.  We have a great Q&A here titled Oversimplify it for me: the correct order of investing in which I go in to more detail, as do 4 other members.  I am not getting on the ""investments will return more than your mortgage cost"" soapbox. A well-funded emergency fund is a very conservative bit of advice. With no matched 401(k), I suggest a balance of the Roth savings and prepayments.  From another great post, Ideal net worth by age X? Need comparison references you should have nearly 1 year's salary (90K) saved toward retirement.  Any question on my advice, add a comment and I will edit in more details."
Staying with your numbers - a 7% long term return will have a tax of 15% (today's long term cap gain tax) resulting in a post tax of 5.95%. On the other hand, even if the student loan interest remains deductible, it's subject to phaseout and a really successful grad will quickly lose the deduction.  There's a similar debate regarding mortgage debt. When I've commented on my 3.5% mortgage costing 2.5% post tax, there's no consensus agreeing that this loan should remain as long as possible in favor of investing in the market for its long term growth. And in this case the advantage is a full 3.45%/yr. While I've made my decision, Ben's points remain, the market return isn't guaranteed, while that monthly loan payment is fixed and due each month.  In the big picture, I'd prioritize to make deposits to the 401(k) up to the match, if offered, pay down any higher interest debt such as credit cards, build an emergency account, and then make extra payments to the student loan.  Keep in mind, also - if buying a house is an important goal, the savings toward the downpayment might take priority. Student Loans and Your First Mortgage is an article I wrote which describes the interaction between that loan debt and your mortgage borrowing ability. It's worth understanding the process as paying off the S/L too soon can impact that home purchase. "None of what I say is advice directed to you. It is how I would continue to analyse the situation you have, were it mine. First off, I prefer to work in certainties more than possibilities.  Saying that, paying down the mortgage makes sense as I can calculate the amount I will save. I also believe that rate rises are coming in the future, based on the talk from the BofE, so any money I pay off now means guaranteed less interest to pay in the future. Also, the lower my loan-to-value ratio, the better/lower interest rates I can receive in the mortgage market. If I do not want to work until retirement age, it'd be nice to have as few bills as possible in the decade or so prior to retirement age. I could then do early-retirement or part-time work in the run-up to retirement. I could use my savings to fund life until retirement pays out. I'd be aiming to put 15% of my gross income into ""future investing"" - using ISAs to build up a savings pot, taking advantage of retirement products. That way all the money is not tied to a normal retirement age before it can accessed. And it's not touchable by future greedy Government taxation... Any income leftover above the 15%, I'd be throwing at the mortgage - taking advantage of the 10% overpay window, remortgaging as LTV comes down. In theory, overpaid mortgage equity is money that could still be accessed (provided house prices don't decline and remortgaging is a possibility). So, in short, I'd follow a plan along these lines of logic. 1) Make sure I have 4-6 months of living expenses as a Rainy Day Fund. Insulate myself from fluctuations in my financial situation. 2) Put away 15% of annual gross income towards ""future saving"". ISAs first, pension second. 3) Overpay the mortgage and look to remortgage as LTV drops. When LTV nears 60%, look to lock in to a longer-term fix. eg. 2 year fixes at 90% LTV, 5 year fixes at 60%. 4) Reassess steps 2 & 3 as life happens, circumstances change, work fluctuates, etc. 5) Once the mortgage is paid off, build as much wealth as possible - ISAs first, then non-tax efficient savings products. Aim for keeping expenses down and raising my savings % rate as much as possible. [Your analysis was thorough and shows you are thinking through consequences. Never forget to factor in the risk of carrying debt. Having no/low debt as you get older means there's more income left to build wealth. Ignore the American view of carrying debt for life and trusting investments to outperform the debt. You have to pay monthly to keep that debt around - and it ain't a pet!]" I think that Dave Ramsey has a good approach to emergency funds. Save $1,000 that is immediately accessible in an emergency, pay off your debts, then build a 3-6 month fund. Two years is great, but takes a really long time to build up. I think rather than take a percentage out, I focus on getting a total amount I consider appropriate for my emergency fund.  Then as for retirement, I do at least what my employer matches, up to the contribution limit.  For example my personal retirement plan in the US has an annual max contribution of $5000. Once I have my 6 to 12 month emergency fund (in a pretty liquid form) and a fully funded retirement, I want to concentrate on building wealth via investments or increasing the quality of my life by spending. Summary answer is:  no percentage for emergency, just get to a total amount you feel comfortable.  Then whatever percentage will allow you to make the most of employer matching and make your retirement fully funded. You are doing great! Congratulations. Check out the Dave Ramsey Baby Steps.  He has advice for exactly your situation. The book Financial Peace covers the topic in detail.  You have an Emergency Fund which is Step 3.  Step 4 is investing 15% for retirement in 401k and similar.  Step 5 is funding college if you have children. In Step 6, he advises putting any extra money towards the principle on your home.  Owning your own home outright is a better goal than investing the money at a higher interest versus your mortgage interest rate. After your are completely debt free, then you can invest and give generously which is Step 7. Answering your question, push your emergency fund to 6 months, bump your retirement saving to 15% and put any extra money to your mortgage. "I think the basic question you're asking is whether you'd be better off putting the $20K into an IRA or similar investment, or if your best bet is to pay down your mortgage.  The answer is...that depends. What you didn't share is what your mortgage balance is so that we can understand how using that money to pay down the mortgage would affect you.  The lower your remaining balance on the mortgage, the more impact paying it down will affect your long-term finances.  For example, if your remaining principal balance is more than $200k, paying down $20k in principal will not have as significant an effect as if you only have $100k principal balance and were paying down $20k of that. To me, one option is to put the $20k toward mortgage principal, then perhaps do a refinance on your remaining mortgage with the goal of getting a better interest rate.  This would double the benefit to you.  First, your mortgage payment would be lower by virtue of a lower principal balance (assuming you keep the same term period in your refinanced mortgage as you have now.  In other words, if you have a 15-year now, your new mortgage should be 15 years also to see the best effect on your payment).  Further, if you can obtain a lower interest rate on the new loan, now you have the dual benefit of a lower principal balance to pay down plus the reduced interest cost on that principal balance.  This would put money into your pocket immediately, which I think is part of your goal, although the question does hinge on what you'd pay in points and fees for a refinance. You can invest, but with that comes risk, and right now may not be the ideal time to enter the markets given all of the uncertainties with the ""Brexit"" issue.  By paying down your mortgage principal, even if you do nothing else, you can save yourself considerable interest in the long term which might be more beneficial than the return you'd get from the markets or an IRA at this point. I hope this helps. Good luck!" "I've heard that the bank may agree to a ""one time adjustment"" to lower the payments on Mortgage #2 because of paying a very large payment. Is this something that really happens? It's to the banks advantage to reduce the payments in that situation.  If they were willing to loan you money previously, they should still be willing.  If they keep the payments the same, then you'll pay off the loan faster.  Just playing with a spreadsheet, paying off a third of the mortgage amount would eliminate the back half of the payments or reduces payments by around two fifths (leaving off any escrow or insurance).   If you can afford the payments, I'd lean towards leaving them at the current level and paying off the loan early.  But you know your circumstances better than we do.   If you are underfunded elsewhere, shore things up.  Fully fund your 401k and IRA.  Fill out your emergency fund.  Buy that new appliance that you don't quite need yet but will soon.  If you are paying PMI, you should reduce the principal down to the point where you no longer have to do so.  That's usually more than 20% equity (or less than an 80% loan).   There is an argument for investing the remainder in securities (stocks and bonds).  If you itemize, you can deduct the interest on your mortgage.  And then you can deduct other things, like local and state taxes.  If you're getting a higher return from securities than you'd pay on the mortgage, it can be a good investment.  Five or ten years from now, when your interest drops closer to the itemization threshold, you can cash out and pay off more of the mortgage than you could now.   The problem is that this might not be the best time for that.  The Buffett Indicator is currently higher than it was before the 2007-9 market crash.  That suggests that stocks aren't the best place for a medium term investment right now.   I'd pay down the mortgage.  You know the return on that.  No matter what happens with the market, it will save you on interest.  I'd keep the payments where they are now unless they are straining your budget unduly.  Pay off your thirty year mortgage in fifteen years." "I'm going to answer your questions out of order. Emergency fund: Depending on how conservative you are and how much insurance you have, you may want anywhere from 3-12 months of your expenses on hand. I like to keep 6 months worth liquid in a ""high-yield"" savings account. For your current expenses that would be $24k, but when this transaction completes, you will have a mortgage payment (which usually includes home-owners insurance and property taxes in addition to your other expenses) so a conservative guess might be an additional $3k/month, or a total of $42k for six months of expenses. So $40-$100k for an emergency fund depending on how conservative you are personally. Down payment: You should pay no less than 20% down ($150k) on a loan that size, particularly since you can afford it. My own philosophy is to pay as much as I can and pay the loan off as soon as possible, but there are valid reasons not to do that. If you can get a higher rate of return from that money invested elsewhere you may wish to keep a mortgage longer and invest the other money elsewhere. Mortgage term: A 15-year loan will generally get you the best interest rate available. If you paid $400k down, financing $350k at a 3.5% rate, your payment would be about $2500 on a 15-year loan. That doesn't include property taxes and home-owners insurance, but without knowing precisely where you live, I have no idea whether those would keep you inside the $3000 of additional monthly home expenses I mentioned above when discussing the emergency fund. That's how I would divide it up. I'd also pay more than the $2500 toward the mortgage if I could afford to, though I've always made that decision on a monthly basis when drawing up the budget for the next month."
