2. Current fee inputs

Use the current provider page, contract, proposal, or dashboard. These editable starting values are not provider rates and should be overwritten before a decision.

Provider platform percentage fee (%)Enter the current platform percentage shown in the provider's pricing page, proposal, contract, or dashboard; do not rely on old comparison articles.Provider platform fixed fee per donation (GBP)Use this for per-donation platform charges, paying-in deductions, fixed transaction costs, or a blended allowance when fees are not only percentage based.Payment processing percentage fee (%)Enter card, wallet, ACH, direct debit, or processor percentage cost from the current provider route being compared, including any nonprofit rate caveats.Payment processor fixed fee per donation (GBP)Enter the fixed processor amount per successful donation, or leave it at zero when the provider route has no fixed per-transaction fee.Gift Aid or tax receipt service fee (%)Enter the provider's Gift Aid, tax receipt, or donation-admin fee percentage; adjust the input if the fee is charged on the reclaim rather than the donation value.Monthly subscription or membership (GBP/month)Enter the monthly platform, membership, event, add-on, CRM, or reporting subscription cost that should be allocated to this donation route.Refund, dispute, or failed-payment allowance (%)Enter a planning allowance for refunds, chargebacks, disputes, failed recurring gifts, duplicate donations, or payment reversals before campaign scale increases.Donor tip or voluntary contribution offset (%)Enter only the portion that reliably offsets charity costs after the supporter sees clear wording; leave at zero if donor trust or conversion risk is uncertain.

3. Reconciliation checks

Payout timing and settlement reports are understoodFinance knows when the money reaches the bank, which report explains each payout, and how donation date, payout date, fee date, and bank date differ.Gift Aid declarations and corrections are mappedThe charity knows where declarations, donor addresses, cancelled declarations, ineligible donations, and exported Gift Aid fields will be reviewed.Refunds, chargebacks, and duplicate donations have ownersSupporter care and finance know who can refund, who reviews disputes, how duplicate gifts are identified, and how reversals reach the accounts.Accounting codes and restricted funds are readyEach donation route can be coded to unrestricted, restricted, campaign, event, grant, or project funds without manual spreadsheet reconstruction.CRM exports and marketing consent are separatedDonor records, recurring gifts, campaign source, email consent, SMS consent, suppression, and stewardship tasks are not mixed into one unclear export.Receipts and donor support wording are checkedThe supporter knows who sends the receipt, what appears on the bank statement, whether the platform contacts them, and how to ask for help.A monthly reconciliation owner is namedA named person checks platform reports, campaign totals, fee deductions, Gift Aid files, refunds, CRM exports, and bank deposits on a schedule.Fee sources and review dates are recordedThe charity records where each fee input came from, when it was checked, whether VAT or country limits apply, and when the comparison must be refreshed.

What this calculator should prevent

Choosing a donation platform from a 0% or low platform-fee claim without modelling payment processing, Gift Aid service fees, subscription fees, refunds, and payout reporting.
Comparing gross donation totals when one route shifts cost to donor tips, voluntary contributions, monthly subscriptions, event add-ons, or finance admin.
Launching a campaign before finance, fundraising, CRM, and supporter-care teams know who owns refunds, receipts, Gift Aid corrections, and monthly reconciliation.
Publishing outdated provider fee claims instead of recording source URLs, proposal dates, caveats, and the next pricing review date.
