Plaintiff appeals as of right from an April 9, 1987, order granting defendant’s cross-motion for summary disposition. We reverse.

Plaintiff was injured in a motor vehicle accident on May 12, 1985, and received no-fault benefits from his insurer, defendant Auto Club Insurance Association. The only issue to be determined on appeal is whether defendant erred in calculating plaintiff’s work loss benefits due to an erroneous interpretation of § 3107(b) of the Michigan no-fault statute. MCL 500.3107(b); MSA 24.13107.

Section 3107(b) reads in part:

The benefits payable for work loss sustained in a 30-day period and the income earned by an injured person for work during the same period together shall not exceed $1,000.00, which maximum shall apply pro rata to any lesser period of work loss.

Since the maximum work loss benefit is adjusted annually to reflect changes in the cost of living, the work loss maximum was $2,347 for the period October 1, 1984, to September 30, 1985. Plaintiff’s purchase of an additional $1,000 in work loss benefits coverage increased plaintiff’s maximum benefit to $3,347._

*39Following the accident, plaintiff misséd work from May 13, 1985, through June 2, 1985. Plaintiff claims he was entitled to work loss benefits of $2,317.14. Plaintiff arrived at this sum by dividing the total maximum benefit allowable, or $3,347, by the number of days he normally worked in a thirty-day period, or twenty-six. The sum derived, $128.73, was then multiplied by eighteen, the number of days plaintiff was unable to work. Thus plaintiff argues he is entitled to $2,317.14.

Defendant paid plaintiff benefits in the amount of $2,024.68. Defendant does not dispute plaintiffs computation of $2,317.14, but argues that plaintiff has failed to complete the calculation. According to defendant, after the maximum benefit is divided by the number of regular workdays, and multiplied by the days actually missed, any income earned by the claimant within the thirty-day period of the accident must be added to the work loss benefits. Thus defendant argues because plaintiff worked for eight days following his eighteen-day work loss, and within thirty days of the first day missed, his earnings for these eight days, figured at $1,322.32, must be added to the maximum benefit payable for the time missed from work, $2,317.16, totalling $3,639.48. From this figure the maximum benefit allowable for the entire thirty-day period as noted above, $3,347, was subtracted. The remainder, $292.48, was the amount deemed to have been earned in excess of the maximum benefits payable for the period of time off work. Defendant then subtracted this figure from the benefits otherwise payable, and obtained the $2,024.68 ultimately paid plaintiff.

We agree with plaintiff and find that defendant has misinterpreted § 3107(b). We do not believe the Legislature intended work loss benefits to be offset with income made outside the period for which *40work loss benefits are being received. The plain language of the statute supports this interpretation. City of Saugatuck v Saugatuck Twp, 157 Mich App 52; 403 NW2d 100 (1987). The section speaks to a "sustained” work loss period, within a thirty-day period. The earned income to be offset must be of this "same period.” Thus we believe the income subject to offset must be earned within the "sustained” work loss period, whether this is thirty days or any lesser period. Moreover, a statutory provision must be read as a whole. People v Einset, 158 Mich App 608; 405 NW2d 123 (1987). The last phrase of the section indicates that the Legislature was not concerned with a calculated maximum based solely on thirty days, but used the thirty-day period as a mere framework to be adjusted pro rata for lesser periods of work loss and earned income. We believe the thirty-day period included in the statute merely serves as a reference point to assess the maximum benefit. This period is not absolute and is be to adjusted according to the actual work loss period.

Reversed and remanded.
