The Fee Savings Calculator: Why We Built It, and What It Tells You

The question every finance pastor asks (and should)

When you run a Pentecostal or charismatic church with 500 to 2,000 members, every pound matters. You know your giving patterns. You know your leakage. You know your Gift Aid reclaim rate, or at least you have a rough sense of what you're leaving on the table.

Then someone shows you new software. They talk about visitor tracking, service rosters, giving apps, HMRC integration. It all sounds good. But the first thing a finance pastor actually thinks is: 'What will this cost us, and what will we save?'

That's not cynicism. That's stewardship.

We built the Fee Savings Calculator because we kept seeing the same pattern. Churches were interested in Ekklesia. They could see the value in the visitor follow-up queue, the 6-stage member establishment ladder, the giving app with Gift Aid Charities Online integration. But they couldn't visualize the actual financial impact. They were doing mental maths with incomplete data.

How it actually works: three scenarios, three years

The calculator doesn't guess. It asks you what you know. Your current branch size. Your average monthly giving per member. Your current tithe leakage rate (the visitors and members who give sporadically or slip away without ever properly committing). Your current Gift Aid reclaim rate, if any.

Then it runs three migration scenarios across a 36-month projection.

Scenario one is conservative. You implement Ekklesia, your leakage reduces by 8 percent over the first year, and you reclaim 60 percent of eligible Gift Aid. Scenario two is moderate. You reduce leakage by 12 percent as the visitor follow-up queue and member ladder do their job, and you hit 75 percent Gift Aid reclaim through the automated HMRC submission panel. Scenario three is optimistic. You reduce leakage by 15 percent (this happens when your pastoral team actually has a structured way to track and respond to visitors and faltering members), and you reclaim 85 percent of Gift Aid (closer to what mature churches achieve).

For each scenario, the calculator shows you the cumulative saving across three years, minus the Ekklesia subscription cost. The number that sits on the screen is not aspirational. It's grounded in what similar churches have actually experienced.

Why we didn't just publish a pricing page

We could have listed the subscription fee and called it a day. But that's not how churches think, and it's not how we think either. A £400-a-month subscription looks expensive in isolation. A £400-a-month subscription that recovers £1,200 a month through reduced giving leakage and automated Gift Aid reclaim is a different conversation entirely.

The calculator is interactive because your church is not the same as the next church. A 300-member branch has different giving patterns than a 2,000-member branch. A church with no Gift Aid reclaim process saves more money by automating it than a church already working with a charities accountant. The calculator lets you put your real numbers in and see your real outcome.

That transparency matters. It builds trust. When a finance pastor sees the three-year projection and realizes that even in the conservative scenario Ekklesia pays for itself and adds surplus, they can take that number to their resident pastor and their finance committee with confidence. This isn't salesmanship. This is stewardship backed by maths.

What we learned from churches that actually used it

The most interesting insight came from a church with 1,200 active members. Their finance pastor ran the calculator and was surprised to find that their Gift Aid reclaim rate was the biggest opportunity, not their giving leakage. They were already doing well on visitor follow-up through manual effort. But they were only reclaiming 30 percent of eligible Gift Aid because the process was slow and scattered.

By moving to Ekklesia's automated Gift Aid Charities Online integration, they could reclaim an extra £800 a month without changing anything else. That alone made the subscription worthwhile.

Another church used the calculator to make the case for implementation to their leadership council. The pastor-in-charge had been skeptical about software overhead. But when the finance pastor walked them through scenario two and showed a net saving of £8,000 across 36 months, the conversation shifted. It wasn't about whether they could afford Ekklesia. It was about whether they could afford not to use the visitor follow-up queue and the structured member ladder when those systems directly fund themselves.

What the calculator does not do (and why that matters)

It doesn't promise to fix a church that doesn't want to engage with its visitors. It doesn't magically increase giving if your branch isn't teaching biblical giving principles. It doesn't turn a disorganised service roster system into a smooth operation if no one uses it.

What it does is quantify the value of doing those things well. The visitor follow-up queue, the member establishment ladder with certificates at each stage, the public giving page and native iOS app, the Gift Aid automation, the service unit rosters with swap requests and check-ins. These tools exist to make your pastoral and administrative work more effective. The calculator shows you what effectiveness is worth.

If you're a finance pastor or resident pastor considering Ekklesia, the Fee Savings Calculator isn't a sales tool. It's a decision-making tool. It's designed to help you see whether this system is right for your branch, and whether the investment aligns with your stewardship priorities.
