Why later closings cost more.

Joining at a later close ends up costing the same as joining at the first, once the catch-up contribution and the interest on it are counted.

A later closing can look like a break — the new LP skipped the fund's earliest capital calls, the initial risk, and the J-curve. They still owe a share of every call that came before them, plus something extra for having waited.

The original rate never changes

When a new LP joins at a later closing, its catch-up contribution for each prior call uses the same rate that applied to everyone else at the time. If the first call was 10 percent of every LP's commitment, the new LP owes 10 percent of its own commitment for that same call — not a blended recalculation across a larger pool, and not a discount for joining late. The rate doesn't change. Who owes a share of it does.

Equalization interest is the extra

The catch-up principal alone would leave the earlier LPs worse off than the new one — their capital was already at work while the new LP's money sat on the sidelines earning nothing for the fund. Equalization interest closes that gap: compensation, set by the LPA, for the months between the due date of the original call and the due date of the new LP’s catch-up. Both amounts go to the fund, which applies them one of two ways: distributed to the partners who funded the original call, pro rata to their capital contributions, or directed among the fund’s vehicles to adjust their relative participation. Only the first is reimbursement, and it compensates the earlier partners for having carried more than their final share. Whatever part of the payment is attributable to the management fee is carved out of both routes and paid to the manager.

Simplified example. Actual equalization interest rates and timing are set in the LPA.

Equalization interest is the cost of arriving after everyone else started, not a penalty for it.

Why the math has to work this way

Without equalization, timing would become a strategy. An LP could hold off committing until a fund's later closings, let everyone else fund the early, riskiest capital, and join at the same ownership percentage without ever having carried the exposure. Equalization interest removes that incentive — a dollar committed on day one and a dollar committed at the final close end up costing the same amount, once the interest is accounted for.

A later closing settles time rather than erasing it.
