A strong 401(k) match is one of the most valuable employee benefits companies can offer. A good match can help employees more than double the value of the money they invest, better assuring their chances of long term financial security. A typical 401(k) match is 50% of contributions up to 6% of the employee's salary, which equates to an extra 3% of the worker's wages going toward retirement savings.

Some companies, however, go well above average when it comes to helping employees save for retirement. The nine companies below will pitch in at least 5% of employees' salaries in the form of 401(k) contributions.

1) This energy titan offers a titanic match

Oil and natural gas giant ConocoPhillips (COP -0.41%) provides a match of 6% for all employees who contribute at least 1% to their 401(k) plans, plus an additional discretionary match of between 0% and 6% depending on factors like the company's performance. The company targets 3% for the discretionary match, putting the targeted match at 9% of an employee's salary. Given the cyclical nature of the energy business, the flexibility in the discretionary match helps the company be generous when times are good and cut back when times are tough without affecting employees' take-home pay.

2) This aerospace giant pays up to 6%

Airline manufacturer Boeing (BA 0.01%) offers employees up to 6% above and beyond their salary in the form of a 401(k) match. Boeing's match is 75% of up to 8% of an employee's salary contributed to the 401(k) plan. While that 401(k) match is a generous one, it's actually part of a replacement for an even more generous pension plan. In addition to the match, Boeing employees transitioning from the pension plan get a percentage of their salaries automatically contributed to their retirement plan, with the long-run target between 3% and 5% based on employee age.

4) This money center bank doubles 6% of employees' contributions

Banking giant Citigroup (C 0.26%) offers employees a 100% match on the first 6% of their salaries contributed to their retirement plans. The company also kicks in an automatic contribution of up to 2% of employees' salaries. Citigroup wasn't the fastest bank to recover from last decade's financial crisis, but now that it's again able to generate billions in profits, the bank looks to be back on much more stable financial footing.

5) This fast-food icon serves up to 7%

Fast food giant McDonald's (MCD 0.38%) offers its employees a three-to-one match on the first 1% of their salaries contributed to the plan, plus a one-to-one match on the next 4%. The company may also make discretionary contributions to employees' accounts; in recent years, it kicked in an extra 2%. In an industry not known for high wages, a strong 401(k) match like that is a great way for employees to get more out of their work than just their paycheck.

6) This credit card company hands out as much as 7.5%

Credit card giant Mastercard (MA -1.19%) offers employees a 125% match on the first 6% of their salaries deferred into their retirement plan. That works out to as much as 7.5% of employees' salaries. It can also make a discretionary contribution of up to 1.25% of employees' salaries. Each time someone swipes or inserts a Mastercard credit card for payment, some of the fees Mastercard collects find their way into the pockets of employees in the form of that 401(k) match.

The company also makes its own contribution between 7% and 15% of employee salaries to the retirement plan, regardless of whether employees contribute. That generous plan contribution means employees can get as much as 20% of their salary put toward their 401(k). Philip Morris International can offer such a generous retirement plan thanks to its popular and addictive product lines, which help to assure repeat sales.

Credit card behemoth Visa (V -0.48%) offers a two-for-one match on the first 3% of salary employees contribute to their 401(k)s, giving employees an additional 6% of their pay. Like Mastercard, Visa makes money every time someone uses one of its cards to make a payment, and the huge volume of transactions it processes around the world enables the company to offer its employees that generous benefit.
