Savings Plan or Lump Sum: What Worked Better for Bitcoin

Savings plan or lump sum for bitcoin? 180 start months since 2011 backtested: when the lump sum came out ahead, when the savings plan did. Check your zone.

Savings plan or lump sum: which was better for bitcoin? If you invested an amount all at once, after twelve months you had more bitcoin than with a savings plan for the same sum in 122 of 180 start months since 2011, 28% more at the median. The savings plan almost only won when the start was close to a cycle high. There, it protected you from losses of 50% and more.

The question that keeps you up at night

You have inherited €12’000, received a bonus or saved for a long time. Now the money is to go into bitcoin. And right now the fear kicks in: what if the price falls 30% next week?

The usual answer is: "Set up a savings plan, then you don't have to pick a moment." The usual counter-answer: "Studies show the lump sum usually wins." Both are true, and neither helps you much on its own.

This article works the question through with real prices: every start month since January 2011, in euros, francs and dollars. You see when the lump sum came out ahead, when the savings plan did, and how you could have told the difference in advance. How the purchase itself works, from opening an account to your own wallet, is in the guide Buying bitcoin in Germany, Austria and Switzerland.

What is being compared

This is about one situation: you have an amount today and are wondering whether to invest it immediately or spread it out.

  • Lump sum: the whole amount on the first of the month at the daily closing price.
  • Savings plan: the same amount in twelve equal installments, the first on the same day, then on the first of each month.

The comparison is who has more bitcoin after the last installment. Since both end at the same price, that is also the comparison of wealth. Fees are not included; they would be similar for both.

If, on the other hand, you save every month from your salary, the question doesn't arise: you buy when you have the money. Collecting first and then buying once is just a later purchase. Which provider suits an ongoing plan is shown in the bitcoin savings plan comparison.

Savings plan or lump sum: the result for every start month since 2011

For each start month, the chart shows how much more or less bitcoin the lump sum had after twelve months. Orange upwards: the lump sum came out ahead. Grey downwards: the savings plan came out ahead.

For each start month since January 2011: the same amount invested at once on the 1st, or in twelve equal buys on the next twelve 1sts of the month. The bar shows how much more (orange) or less (grey) bitcoin the lump sum ended with, on a log scale. Daily closes in US dollars (Coin Metrics until 10 Jan 2018, then OKX), before fees.

Three patterns stand out right away:

  1. Orange dominates. In 122 of 180 start months, the lump sum came out ahead, that is 68%.
  2. The grey bars come in blocks. They stand before the crashes after the highs of 2011, 2013, 2017, 2021 and 2025.
  3. The swings are getting smaller. From 2011 to 2013, the lump sum sometimes brought four times as much. Since 2015, it has ranged from 51% behind to 193% ahead.

Whether you calculate in euros, francs or dollars hardly changes anything: in euros the lump sum came out ahead in 121 cases, in francs in 120. The prices come from this site's daily close file, euros and francs at the ECB reference rates.

How long the savings plan runs changes the result

The longer you spread it out, the longer part of your money sits unused on the side. With a price that rose over the long term, that costs.

24 months16874%+78%

How the comparison is calculated

Lump sum: bitcoin = amount ÷ price at the start

Savings plan: bitcoin = (amount ÷ 12) ÷ price₁ + (amount ÷ 12) ÷ price₂ + … + (amount ÷ 12) ÷ price₁₂

Lead = lump-sum bitcoin ÷ savings-plan bitcoin − 1

Example Jan 1, 2023, €12’000: lump sum 12’000 ÷ €15’578 = 0.770 BTC. Savings plan: twelve installments of €1’000 come to 0.483 BTC. Lead 0.770 ÷ 0.483 − 1 = +60%.

The chart uses a logarithmic scale: twice as much bitcoin (+100%) and half as much (−50%) are the same distance from the zero line.

By the way, it is similar with stocks. In 2023, Vanguard compared a lump sum with spreading over twelve months in the global stock market from 1976 to 2022: the lump sum came out ahead in 68% of cases. With bitcoin the gap is larger, in both directions.

Year by year: €12’000 on January 1

This is what it looks like in practice. Each year on January 1, €12’000 at once or €1’000 a month:

Seven of twelve years went to the lump sum. The savings plan's five years almost all started in the hot zone, shortly before or after a high. 2021 is the exception: the start was hot, but the rise continued for another ten months.

The year 2025 also shows the effect of the exchange rate. In dollars, the lump sum was a good 5% ahead; in euros and francs, 2% behind, because the dollar weakened over the year. For savers in euros or francs, what counts is the calculation in their own currency.

The zone at the start decided almost everything

This site's Power Law model assigns every day to one of five zones, depending on how far the price is above or below its trend. Sorting the 180 start months that way makes the picture very clear:

Zone at startStart monthsLump sum aheadMedian lead
Floor5100%+76%
Accumulation50100%+58%
Fair9069%+24%
Hot3216%−29%
Euphoria30%−22%

Twelve months, daily closing prices in US dollars, without fees. As of Nov 12, 2026.

Below fair value, the lump sum never had less bitcoin after twelve months; in the closest case (July 2022) it still had 12% more. In the hot zone, it was almost the reverse. What the zones mean and how often the price was in each is explained in The bitcoin valuation zones from floor to euphoria.

What the tables don't show: how it feels

On paper, the lump sum usually came out ahead. But if you invested on the wrong day, you had to endure a great deal.

Starting on Jan 1, 2018 was similar: −75% with the lump sum, −54% with the savings plan. A 54% loss hurts too. But −71% on the whole amount is, for many people, the moment they sell, right at the bottom.

That is the real value of the savings plan: it is insurance against your own reaction. If you sell after a crash, you lose more than the lump sum would have gained on average. How to get through such phases is described in HODL psychology: handling volatility. How deep and long the past crashes were is shown in All bitcoin bear markets compared.

The middle way: half now, half spread out

You don't have to choose an extreme. If you invest half right away and spread the rest over twelve months, your result always lands exactly between the two.

Since 2011, twelve monthsLump sumHalf and halfSavings plan
Median lead+28%+14%0
Worst start month−66%−33%0
Best start month+362%+181%0

All values measured against the savings plan, in bitcoin after twelve months. Daily closing prices in US dollars, without fees.

So half and half costs you half the typical advantage and spares you half the worst shortfall. For many people, that is the point at which they sleep well.

What this means for you today

On Nov 12, 2026, one bitcoin cost $71’461, €64’490 or CHF 59’537. The trend was at $108’723, so the price was at 0.66 times the trend, in the accumulation zone and just under 7% above the floor.

The last twelve months, however, show why this is no guarantee. Anyone who started on Dec 1, 2025 at €74’088 in the fair zone had 16% more bitcoin with the savings plan than with the lump sum after twelve months. The price kept falling during that time.

How to decide in three questions

  1. Where is the price? Below fair value, the lump sum has always come out ahead so far; in the hot zone, almost never. Look at the current zone before you decide.
  2. Would you sit out a 70% loss? If not, spread it out. A savings plan you stick with beats a lump sum you sell at the bottom.
  3. Do you have a fixed plan for the rest? Set up the savings plan right away, with a fixed amount and a fixed day. If you wait "for a better moment", you often end up holding nothing at all.

Two more points:

  • Interest on the waiting money changes little. At 2% in an instant-access savings account, the money not yet invested in the savings plan brings in about 1% more, compared with a typical gap of 28%.
  • Taxes: In Germany, each savings plan installment has its own one-year holding period. So the last purchase becomes tax-free eleven months later than with the lump sum. In Austria and Switzerland this doesn't matter (as of 2026). More in Bitcoin taxes in Germany.

How much should go into bitcoin overall is a different question from how. Record your goal in sats and years in My Goal.

Frequently asked questions

Is a savings plan better than a lump sum for bitcoin?

Not on average. Since 2011, the lump sum came out ahead after twelve months in 68% of start months. The savings plan was better when the start was close to a cycle high, and in every case it reduced the largest interim losses.

Should I invest an inheritance in bitcoin all at once?

That depends on where the price is and what you can stand. Historically, the lump sum always came out ahead below fair value, but in the hot zone in only 16% of cases. If you are unsure, invest part right away and spread the rest over six to twelve months.

Over how many months should I spread it?

The shorter, the closer you are to the lump sum. Over three months, the lump sum came out ahead in 60% of cases; over two years, in 74%. Six to twelve months is a common compromise.

What is the cost-average effect?

With a fixed amount, you buy more bitcoin when the price is low and less when it is high. Your average price is therefore below the average of the prices on your purchase dates. But that only brings more bitcoin than a lump sum if the price falls during that time.

Is a savings plan worthwhile in a bear market?

Yes, especially there. A savings plan through the 2018 and 2022 bear markets bought at much lower average prices than a purchase at the high. How to buy by rules instead of gut feeling in a bear market is shown in Buying bitcoin in a bear market.
