No more spreadsheet errors on capital calls
You're calling $500K of capital from 15 LPs with different commitment amounts, two late closers who owe equalization interest, and one LP who negotiated a reduced management fee. You open your Excel spreadsheet, stare at the formulas, and pray you don't send the wrong amount to the wrong person. There's a better way.
Start your free trialPro rata capital call calculations seem straightforward until they're not. A $10M fund with 15 LPs at different commitment levels, some joining at a subsequent close, with management fees calculated quarterly in advance — the math gets complex fast. And unlike most spreadsheet errors, getting a capital call amount wrong is something your LPs will notice immediately.
Most emerging managers build their capital call spreadsheet from scratch or adapt a template they found online. The formulas work for the simple case, but break when you add late closers with equalization payments, LPs with side letter fee arrangements, or follow-on investments that draw from recycled capital. One broken VLOOKUP and you're sending correction notices to your investors.
Archstone's pro rata calculator pulls commitment data directly from your LP records, applies the correct allocation methodology for every scenario, and shows you exactly what each LP owes before anything goes out. Every calculation includes a full audit trail so you — and your fund admin — can verify the math.
Enter the total capital call amount and Archstone calculates each LP's share based on their commitment percentage. The system pulls live commitment data from your LP records — no manual entry, no copy-paste from another spreadsheet, no risk of using outdated numbers.
Not every LP has funded their full commitment yet. The calculator tracks funded versus unfunded capital for each LP and correctly calculates the callable amount based on remaining unfunded commitments. No more manually adjusting formulas when an LP's available capital changes.
LPs joining at a subsequent close need to equalize with existing investors. Archstone automatically calculates the catch-up amount including any equalization interest specified in your LPA. The math accounts for prior capital calls, management fees already charged, and the interest rate on the equalization payment.
Some LPs have side letters with modified economics. Override the standard pro rata calculation for specific investors without breaking the math for everyone else. The system flags overrides clearly so your fund admin can review non-standard allocations before notices go out.
Every pro rata calculation is logged with the inputs, methodology, and outputs. See exactly how each LP's amount was derived — commitment basis, percentage ownership, any overrides applied, and the final callable amount. Your fund administrator and auditor get a clear paper trail for every call.
Review the complete capital call breakdown before any notices go out. See each LP's name, commitment, pro rata share, callable amount, and any special notes — all in a clean summary view. Catch errors before they reach your investors, not after. Edit and recalculate instantly if anything looks off.
Fund I just had its final close. You need to call capital for your first investment plus organizational expenses and the management fee. Enter the total amount, and Archstone splits it across all LPs pro rata — including the late closers who owe equalization from the first close. One click, zero spreadsheet anxiety.
A portfolio company is raising their Series A and you're exercising your pro rata. The follow-on investment comes from remaining unfunded commitments. The calculator adjusts each LP's callable amount based on what they've already funded, ensuring fair allocation across the entire investor base.
Management fees are called quarterly, but three of your LPs have reduced fee arrangements via side letters. The calculator applies the standard 2% rate to most investors and the negotiated rates for side letter LPs automatically. No manual adjustments, no risk of overcharging a discounted LP.
The calculator allocates capital calls proportionally based on each LP's unfunded commitment as a percentage of total unfunded commitments. This is the standard methodology used by institutional fund administrators. For management fees, it calculates based on committed capital during the investment period and net invested capital thereafter, per your LPA terms.
Late closers are automatically calculated to equalize with existing investors. The system computes the catch-up amount based on prior calls they missed, adds equalization interest at the rate specified in your LPA, and includes their pro rata share of the current call. All three components are itemized clearly in the notice.
Yes. You can apply custom overrides for LPs with side letter arrangements, reduced fees, or special allocation rights. Overrides are flagged visually in the preview so your fund admin can review them before notices are sent. The audit trail records both the standard calculation and the override applied.
Yes. Once you finalize the pro rata calculations, you can generate personalized capital call notices for every LP with one click. Each notice includes the LP-specific amount, wire instructions, and payment deadline. The entire flow — calculate, review, generate notices, send — happens in one connected workflow.
