Summary Prospectus for New Investors
May 1, 2024

This Summary Prospectus summarizes key features of your individual flexible payment annuity contract (the "Contract"). Before you invest, you should also review the prospectus for the Contract, which contains more information about the Contract's features, benefits, and risks. This Summary Prospectus describes two classes of the Contract: a front-load version (in which a sales charge is assessed when Purchase Payments are made) and a back-load version (in which a sales charge is assessed if and when amounts are withdrawn). You can find this prospectus and other information about the Contract, including the annual and semi-annual reports for your underlying Portfolios, online at www.nmprospectus.com. You can also obtain this information at no cost by calling (866) 910-1232 or by sending an email request to [email protected].

You may cancel your Contract within 10 days of receiving it without paying fees or penalties.
In some states, this cancellation period may be longer. Depending on your state of issue, upon cancellation you will receive either the full amount of your Purchase Payment(s) or your Contract Value. You should review the prospectus, or consult with your financial representative, for additional information about the specific cancellation terms that apply.

Additional information about certain investment products, including variable annuities, has been prepared by the Securities and Exchange Commission's staff and is available at www.Investor.gov.

The Securities and Exchange Commission ("SEC") has not approved or disapproved the Contract or passed upon the adequacy of this Summary Prospectus. Any representation to the contrary is a criminal offense.

Each Division of the Separate Accountinvests exclusively in shares of a single series of a Fund (i.e., an underlying Portfolio).

Glossary of Special Terms

Unless otherwise specified in this prospectus, the words "Northwestern Mutual," "we," "us," "our," and "Company" mean The Northwestern Mutual Life Insurance Company. The words "you" and "your," unless otherwise specified, mean the Contract Owner. We use a number of special terms in this summary prospectus, including the following:

Accumulation Unit-An accounting unit of measure representing the Contract Value, before the date on which Annuity Payments begin, in one or more Divisions of the Separate Account. The related term "Accumulation Unit Value" ("AUV") means the value of a particular Accumulation Unit at a particular time and is analogous to, but not the same as, the share price of a mutual fund.

Annuitant-The person upon whose life the Contract is issued and Contract benefits depend. The Primary Annuitant is the person upon whose life the Contract is initially issued. The Contingent Annuitant is the person who becomes the Annuitant upon the death of the Primary Annuitant. If the Contract is annuitized under a single life income plan, there will be one Annuitant. If the Contract is annuitized under a joint life income plan, there will be two Joint Annuitants.

Annuity Payments-Money we pay pursuant to the terms of the Contract. Payments may be paid under one or more of the following three methods: (1) a variable income plan; (2) a fixed income plan; or (3) in cash.

Annuity Unit-An accounting unit of measure representing the actuarial value of a variable income plan's interest in a Division of the Separate Account after Annuity Payments begin.

Company-The Northwestern Mutual Life Insurance Company

Contract-The agreement between you and us described in this variable annuity prospectus. During the accumulation period of the Contract, you may invest money under your Contract and any earnings on your investment will accumulate on a tax-deferred basis. During the annuitization period, you receive periodic payments based largely on the amounts you accumulate, all or a portion of which will be taxable as ordinary income.

Contract Value-The value of your Contract on any Valuation Date is the sum of: (1) the value of your amounts held in the Divisions of the Separate Account on that Valuation Date; and (2) the sum of your amounts allocated to any Guaranteed Account(s), plus credited interest; less (3) any applicable fees and amounts withdrawn or transferred from the Guaranteed Account(s).

Division-A sub-account of the Separate Account, the assets of which are invested exclusively in the shares of one of the Portfolios of the underlying Funds.

Fund-A Fund is registered under the Investment Company Act of 1940 (the "1940 Act") as an open-end management investment company or as a unit investment trust, or is not required to be registered under the 1940 Act. A Fund is available as an investment option under the Contract. The assets of each of the Divisions of the Separate Account are used to purchase shares of the corresponding Portfolio of a Fund.

General Account-All assets of the Company, other than those held in the Separate Account or in other separate accounts that have been or may be established by the Company.

Guaranteed Account-A fixed investment option under the Contract, supported by the assets held in the Company's General Account, that has a term of a specified duration (called a "Guaranteed Period").

Overview of the Contract

The Contract is an individual flexible payment variable annuity contract, the purpose of which is primarily to provide for the accumulation of value through variable or fixed investment options, through allocations to a variety of Portfolios and/or fixed account options, and payment of annuity benefits on a fixed or variable basis. The Contract is sold for use under a variety of tax-qualified and nontax-qualified plans and may be appropriate if you have a long-term investment horizon. It is not intended for short-term investment and is therefore not appropriate for people who may need to make early or frequent withdrawals or who intend to engage in frequent trading.

During the years when funds are being paid into your Contract , known as the accumulation (savings) phase, the earnings accumulate on a tax-deferred basis. The annuitization (income) period begins when you start receiving a stream of periodic annuity payments under your Contract that begin on the date you select, and all or a portion of such payments will be taxed as

ordinary income. Once you annuitize your Contract, your withdrawal rights will depend on the income plan selected. The amount you accumulate under your Contract, including the results of investment performance of your Divisions and interest earned under the fixed options will determine the amount of your monthly annuity payments. Additional information about the Portfolios in which the Divisions invest is provided in the Appendix (see "Appendix A: Portfolios Available Under Your Contract).

In addition to the Divisions which vary with the investment experience of the underlying Portfolios, the Contract offers two fixed options (Guaranteed Interest Fund 1, or GIF 1, and Guaranteed Interest Fund 8, or GIF 8) that credit interest at declared rates.

Below are other features and options that the Contract offers.

The Automatic Dollar Cost Averaging Plan allows you to transfer a set amount from the Government Money Market Division to other Divisions on a regular schedule. The Portfolios Rebalancing feature automatically rebalances your Contract Value among your selected Divisions in order to restore your allocation to the original level. You may participate only in one of the Automatic Dollar Cost Averaging Plan and Portfolios Rebalancing feature at a time. We also allow automatic transfers or sweeps of interest from the GIF 1 to any combination of the Divisions monthly, quarterly, semi-annually or annually. We do not charge for participation in these features.

The Systematic Withdrawal Plan allows you to set up automatic monthly withdrawals from your Contract Value. We will take any withdrawal under this plan proportionally from your Contract Value in your selected investment options or the investment options you designate subject to certain conditions. We do not charge for participation in this feature.

The Terminal Illness Benefit allows you to withdrawal all or a portion of your Contract Value without incurring a Withdrawal Charge if the Primary Annuitant is terminally ill (as defined in the Terminal Illness Benefit Rider) and has a life expectancy of 12 months or less. The Nursing Home Benefit allows you to withdraw all or a portion of your Contract Value without incurring a Withdrawal Charge if the Primary Annuitant has been confined for at least 90 consecutive days to a licensed nursing facility or hospital and certain other conditions are satisfied. See the prospectus for a full explanation of the required conditions. The Terminal Illness and Nursing Home Benefits are not available in New York.

Buying the Contract

You may make Purchase Payments monthly, quarterly, semiannually, annually, or on any other frequency acceptable to us. For back-load Contracts in non-tax qualified situations, the minimum initial Purchase Payment is $5,000. For all other back-load Contracts, the minimum amount for an initial Purchase Payment is $100 ($25 if on an Insurance Service Account (ISA)). For front-loadContracts, the minimum initial Purchase Payment is $10,000. The minimum amount for each subsequent Purchase Paymentfor all Contracts is $25, although we may accept lower amounts in certain circumstances. We will accept larger Purchase Payments than the minimums, but total Purchase Payments under any Contract may not exceed $5,000,000 without our consent. For all Contracts, Purchase Payments may not exceed the applicable federal income tax limits. In certain situations, we may, in our discretion, reduce or waive our minimum purchase payment requirements. When initial Purchase Paymentsrepresenting proceeds from rollovers or annuity exchanges are determined to satisfy the front-load Contract minimum based on values at the time you sign your application, but the amount subsequently received by us is less than the required minimum due to market value fluctuations and sales or administrative fees charged in connection with the rollover or exchange, we may reduce the required minimum by the sum of any such depreciation and fees.

Guaranteed Accounts are subject to certain investment minimums and maximums in addition to those described above. Amounts that are applied to GIF 8 are subject to an investment minimum of $10,000, unless we consent to a lesser amount. We also limit the maximum amount that may be invested in the Guaranteed Accounts. Without our prior consent, no investment

may cause the Accumulation Value of all Guaranteed Accounts (the sum of all applied amounts and credited interest, less fees and any amounts transferred or withdrawn) to exceed a maximum amount we specify in the Contract. For Contracts currently being issued, the maximum amount specified in the Contract is $100,000.

We credit Net Purchase Payments, after deduction of any sales load, to the variable and/or fixed investment options as you direct.

Initial Net Purchase Payments allocated to a Division will be priced at the Accumulation Unit Value determined no later than two Valuation Dates after we receive at our Home Office or a lockbox facility we have designated both your initial Purchase Paymentand your application in good order. "Good order" means that the application is complete and accurate and all applicable requirements are satisfied. If your application is not in good order, we may take up to five Valuation Dates to resolve the problem. If we are unable to resolve the problem within that time, we will notify you in writing of the reasons for the delay. If you revoke the consent given with your application to hold your initial Purchase Payment pending resolution of the problem, we will return your payment. Otherwise, the number of Accumulation Units you receive for your initial Net Purchase Payment will be determined based upon the valuation of the assets of the Divisions you select not later than two Valuation Dates following the date on which the problem is resolved and your application is put into good order. Subsequent Net Purchase Payments will be priced based on the next determined Accumulation Unit Value after the payment is received in good order either at the Home Office or a lockbox facility we have designated.

We deem receipt of a Purchase Payment to be received on a given Valuation Date if receipt occurs before the close of trading on the NYSE (typically, 4:00 p.m. Eastern Time). If receipt occurs on or after the close of trading on the NYSE, we deem receipt to occur on the following Valuation Date. We determine the value of an Accumulation Unit in each Division by multiplying the value on the immediately preceding valuation date by the net investment factor for the Division. The net investment factor takes into account the investment experience of the Portfolio and the deduction for any applicable taxes or charges.

Making Withdrawals: Accessing Money in Your Contract

ContractOwners may withdraw some or all of the Accumulation Unit Value of their Contract at any time before the Maturity Date. We may require that a Contract Value of at least $2,000 remain after a partial withdrawal. You may instruct us how to allocate your partial withdrawal request among your investments in the Divisions and Guaranteed Accounts. If no direction is received, your withdrawal will be deducted proportionately from each of your investments. Withdrawals of amounts from the fixed account options are subject to special restrictions, charges and other adjustments. Any applicable withdrawal (or surrender) charge, market value adjustment, federal/state tax withholding, and/or Express Mail Delivery fee will be assessed against and deducted from the amount withdrawn.

Withdrawals may also be made after the Maturity Date. If Annuity Payments are being made under variable income plan 1 (Period Certain), the payee may surrender the Contract and receive the value of the Annuity Units credited to his or her Contract, less the applicable withdrawal charge. If Annuity Payments are being made under variable income plan 2 (Single Life Income with or without Period Certain) and the payee dies during the period certain (or if both payees die during the period certain of variable income plan 3 (Joint and Survivor Life Income with Period Certain)), the Beneficiary may surrender the Contract and receive the withdrawal value of the unpaid payments for the period certain. The withdrawal value is based on the Annuity Unit value on the withdrawal date, with the unpaid payments discounted at the Assumed Investment Rate.

We process withdrawal requests at the Accumulation Unit Value next determined only after our receipt of your request in good order, which includes satisfaction of all our administrative requirements. Subject to our administrative procedures and our approval, you may request that a withdrawal be processed (or that an Income Plan start) on a future date you specify. Otherwise, we will pay the amount of any withdrawal from the Separate Account within at least seven days after we receive the request in good order unless the suspension of payments or transfers provision is in effect or if required by government regulators. Withdrawals reduce your Contract Value and may be subject to unfavorable tax consequences.

If mandated under applicable law, we may be required to block an Owner's account and thereby refuse to pay any requests for transfer, partial withdrawal, surrender or death benefits, until instructions are received from the appropriate regulator. We may also be required to provide additional information about an Owner and an Owner's account to government regulators.

Examples1

The following Examples are intended to help you compare the cost of investing in the Contract with the cost of investing in other variable annuity contracts. These costs include ContractOwner transaction expenses, annual Contract fees, and the fees and annual Portfolio expense. The Examples assume that you invest $100,000 in the Contractfor the time periods indicated and that your investment has a 5% return each year. The Examples reflect the maximum expenses of the underlying Portfolios(as set forth above) as well as the Optional Enhanced Death Benefit Maximum Charge. Although your actual costs may be higher or lower than those shown below, based on these assumptions, your costs would be as follows:

Back-Load Contract With the Enhanced Death Benefit

	1 year	3 years	5 years	10 years
If you surrender your Contract at the end of the applicable time period:	$10,120	$18,571	$25,166	$43,305
If you annuitize at the end of the applicable time period:	$4,120	$12,571	$21,166	$43,305
If you do not surrender your Contract:	$4,120	$12,571	$21,166	$43,305

Front-Load Contract With the Enhanced Death Benefit

	1 year	3 years	5 years	10 years
If you surrender your Contract at the end of the applicable time period:	$7,698	$14,352	$21,225	$39,412
If you annuitize at the end of the applicable time period:	$7,698	$14,352	$21,225	$39,412
If you do not surrender your Contract:	$7,698	$14,352	$21,225	$39,412

Please remember that the examples are simply illustrations and do not represent past or future expenses. Your actual expenses may be higher or lower than those shown in the examples. Similarly, your rate of return may be more or less than the 5% assumed in the examples.
