Private portfolio worksheet

Know what your crypto lots are worth—without uploading your holdings

Add each acquisition as its own lot. AfroTools calculates a current planning snapshot only when the public market endpoint returns source rows within its 30-minute freshness contract.

P/L covers only lots with an entered all-in cost. Unknown-cost lots are never blended into the P/L figure.

How cost coverage works

A lot with no acquisition cost can still contribute to current value, but it cannot contribute to P/L. Coverage shows what share of current value has a known cost.

What happens when data is unavailable?

The worksheet shows no estimated, stale, converted or zero substitute values. If a held asset is missing from the fresh snapshot, every dependent total is withheld.

Is this a transaction or tax ledger?

No. It does not model disposals, historical exchange rates, taxable events or jurisdiction-specific cost-basis rules. Use exchange records and a qualified adviser for reporting.

Where do prices come from?

The AfroTools crypto-prices endpoint validates CoinGecko rows and supports NGN and ZAR only. Each accepted row must be no older than 30 minutes.

Planning snapshot only. Crypto markets are volatile. This tool is not financial, tax or investment advice and does not recommend assets or allocations.
