To pay off my mortgage or save for pension ?

I’ve been feeling stressed about this and similar to another thread, I would really
appreciate some advice but realise there may be no right answer.

I’m 39, single and live in a small flat but k do love it. Can’t see my circumstances changing anytime soon and will possibly never move. My mortgage is now £140,000.

I am wondering whether I should overpay it as much as possible and look to clear it asap in the next five years. However, I’m a freelancer and I have barely no pension. Just £3000 in a SIPP. No employer one. And I’ve been stressing as to whether I should really be making my overpayments into my SIPP instead?

please help - what would you do?

if I was planning to move later on, is it worth paying off my mortgage now?

thank you!

@TheHedgehogCannotBeBotheredAtAll that makes no mathematical sense at all

I think she's talking about leveraged gains.

So long as you continue with your mortgage repayments, you'll be mortgage free before you retire.

So to me, the best choice is a pension, one that is medium to higher risk, so more equities, you've enough time to ride out dips and troughs, sure there is risk but there is in anything, you might have poor health... anything can happen but the chances are they wont, so having a bit more than the SP is a good idea.

If you pay off Mortgage early, you wont have enough time to build a good pension, even with higher payments in, unless you re talking very large repayments ie 10s of 1000's

still doen't work mathematically

LizzieSiddal · 14/01/2026 13:44

It doesn’t need to be one or the other, Dh and I are self employed and we did both. Half of any money went on over paying the mortgage and the other half went into the pension. If an extra lump sum came in through work, that went into the pension because of the tax benefits.

say 2 people buy identical 250K houses one deposits 50K and has a mortgage for 200k (£1050 a month for 25 years)
the other person owns it outright so now has no mortgage payment
5 years later both houses worth 300K
the person with mortgage has paid off about 25,000 off mortgage in this time so now in theory has a 300k house with 175k outstanding and 125K equity their 50K deposit has given them 125K of course minus 5 years repayments of 63K so a balance of 62k so net increase is 12k on their 50k deposit in 5 years which equates to 24% over 5 years ( 50,000 invested at 4.5% would have had same gain)
however their neighbours have a similar increase of 50K in house value and of course no monthly payments so a saving of 63k even if not invested they now have 363K so if they wanted to move to a 500K house they have 363K deposit and would need a small mortgage of 137K ( however 63K invested would be more like 68 just in a 3.5% bank savings account and 77k if invested in stocks and shares type ISA)
the neighbours would now have a 125K deposit and need a 375K mortgage to move to 500K house
while notionally you can say the initial investment of 50K deposit by original couple is now worth 125K a leveraged gain of 150% but this gain is offset by payments etc

while the gain of couple B is 50K on their house, a 20% gain
couple B have a much healthier financial situation overall as for overall personal finances you have to factor in money saved from not having a mortgage payment and the fact that it will gain interest too

but looking at net worth altogether couple B being mortgage free are saving and investing and growing money in a more sustainable way

leveraged gain works in business so you can borrow to expand and invest at a greater rate for better long term yields than waiting until you can cash flow everything but in terms of house buying for a single family home as opposed to a string of rental properties is not really the answer

it is a completely different question that if you have £1000 a month spare are you better investing it or overpaying mortgage ... you are better investing it mathematically so the couple with mortgage there is no really advantage in paying mortgage off with extra savings but for the couple with the paid off house there is absolutely no point in getting a mortgage uness they want to upsize and now having a 300k house ( even if they didn't save a penny of what would be a mortgage payment) they have a 300K deposit for 500k house the couple with current mortgage have a 125k deposit once you have a LTV of less than 50% you can get very good mortgage deals so even if both couples need a mortgage for 500K house the couple with 300K deposit will get a better rate albeit probably 0.5-1%

Pension contributions are tax free savings and it’s probably are more sensible option. You can then pay off the mortgage with any lump sums

BirdytheHero · 14/01/2026 15:09

@Cottagecheeseisnotcheese You've missed the opportunity cost, which is the key thing- the person with a £200k mortgage has £200k to do other things with, things which are likely to do better than the interest cost on the mortgage. (Unless you're just arguing that it's better to have £250k than £50k, in which case no argument from me 😂)

Less importantly (in the first years of a mortgage) you're treating the mortgage payments as simply gone whereas in fact they will be partially a repayment of capital.

Just be aware that a private pension is taken off any benefits you may ever claim. While mortgage free, or having a low mortgage, you will always gain. As a single person you may need top up benefits in the case of illness/disability etc.

This.

Pension is savings/future planning but mortgage is debt - clearing it offers an important security if you’re single and self employed.

I would try to do a bit of both, but prioritise overpaying mortgage when you have extra cash.

3point5 · 14/01/2026 15:16

Does it have to be a binary choice? . I would probably put the majority of my free cash into pension savings but also just chip away a little bit at the mortgage too because it is quite emotionally satisfying.

Whenever there is a " loose change" amount in my accounts I ping that into the mortgage as an overpayment and it's just a little satisfying way to chip away it a bit more

Cottagecheeseisnotcheese · 14/01/2026 16:02

@BirdytheHero I did not ignore the part capital repayments I said specifically in first 5 years you would repay approx 25K of the capital, 125K made up of 50k deposit 50k rise in house price 25k repayment of capital therefore increasing equity but you still made 63k in payments 25k produced equity 38k being interest

In the real world the people do not have 200k to do something else with as the vast majority of people with 200k spare would have either borrowed less or brought a bigger house,
if they genuinely had 200k and chose to invest it in stock market rather than taking a smaller mortgage and use the interest to pay off mortgage getting 8% on stock market which maybe taxable if not in ISA to offset 5% interest rate there is a net gain depending on tax of 3% you may be lucky and the stock market has a good year like last year when it gained 20% but the longterm average over decades is 8% and obviously the 200k (-ongoing repayments) in stockmarket would generate more growth than the couple drip feeding the cost of repaymments into stock market
none of the above count for the peace of mind knowing your house is not vulnerable if you lose your job or get sick you wouldn't need term life insurance for the mortgage ( though if you are young and healthy this is normally not very much at all)
you get the same thing on things like location location location someone has max budget of 300K ( probably 30k deposit 270K mortgage ) if you get the house for 275k, they will not have 25k floating around; the 10% deposit would be 27.5K with slightly smaller mortgage as the lender will not give them a 270 mortgage on 275k house if they had saved the 30K they would have 2.5k spare for decorating etc it looks like you have saved 25k but it is not really available to spend

What we are discussing is a specific PP's decision to pay off the mortgage rather than maintain a mortgage + make a leveraged gain on the house + have the money free to invest elsewhere. So in the real world she did have money to invest elsewhere. You told her her post made no mathematical sense when in fact it did make sense (although was perhaps not phrased perfectly).

You mentioned the capital repayment but then treated the whole sum (capital + interest) as being lost.

You are right of course that someone might quite reasonably choose to pay off a mortgage for reasons of security, even if it doesn't make the best sense financially.

Leaving this now as we are not getting anywhere.

The risk with aggressively overpaying your mortgage is that you end up property rich but pension poor. You can’t live in your flat and sell chunks of it to fund retirement.

It doesn’t have to be all or nothing. You don’t have to choose one or the other.

  1. Prioritise getting something meaningful into your pension. Aim for 10-15% of your income. If that feels too much right now start lower but start consistently.
  2. Then overpay the mortgage with surplus income in good months, which keeps things flexible.

Every £100 you put into your SIPP only costs you:

£80 if you’re a basic-rate taxpayer
£60 if you’re higher-rate (after reclaiming)

That’s an instant, guaranteed return your mortgage overpayments simply can’t match.

Overpaying saves you interest at roughly your mortgage rate (say 4–6%). That’s solid — but it’s post-tax and usually lower than long-term pension growth plus tax relief.

You’re in a better position than a lot of people and you still have enough time to maximise your pension.

It depends on your income. Anything over 50k you can spare should go into your pension as you’ll get higher rate tax relief of 40%.

This. The tax implications are massively significant. If you’re a higher rate tax payer there is far more incentive to pay into your pension.

Papyrophile · 14/01/2026 21:06

Once you have a decent % of home equity, then your emphasis should be your pension because the government want you to save for your old age and will give you tax breaks. Pension is your priority so you have years to compound. Inflation will automatically reduce the value of your mortgage.

FrizzyFrizbee · 15/01/2026 13:24

Overpaid our mortgage until it was paid off. No regrets, so glad we did it.

FrizzyFrizbee · 15/01/2026 13:31

Just to say as well that having paid off the mortgage, it freed up the possibility to put money into other savings and investments. Those savings and investments have performed better than my pension, which having just checked today is a fair amount less than it was in value in 2022, which is when I started putting money into guaranteed income bonds and ISAs etc. I am not drawing my pension yet, so the value could increase, but it must first make up what has been lost.

Ideally I think it’s good to have several pots, but I would make the same decision today as I did back then to pay off my mortgage.
